salt.modules.x509_v2

Manage X.509 certificates

depends:

cryptography

New in version 3006.0: This module represents a complete rewrite of the original x509 modules and is named x509_v2 since it introduces breaking changes.

Note

  • PKCS12-related operations require at least cryptography release 36.

  • PKCS12-related operations with Edwards-curve keys require at least cryptography release 37.

  • PKCS7-related operations require at least cryptography release 37.

Configuration

Explicit activation

Since this module uses the same virtualname as the previous x509 modules, but is incompatible with them, it needs to be explicitly activated on each minion by including the following line in the minion configuration:

# /etc/salt/minion.d/x509.conf

features:
  x509_v2: true

Peer communication

To be able to remotely sign certificates, it is required to configure the Salt master to allow Peer Communication:

# /etc/salt/master.d/peer.conf

peer:
  .*:
    - x509.sign_remote_certificate

In order for the Compound Matcher to work with restricting signing policies to a subset of minions, in addition calls to match.compound_matches by the minion acting as the CA must be permitted:

# /etc/salt/master.d/peer.conf

peer:
  .*:
    - x509.sign_remote_certificate

peer_run:
  ca_server:
    - match.compound_matches

Note

When compound match expressions are employed, pillar values can only be matched literally. This is a barrier to enumeration attacks by the CA server.

Also note that compound matching requires a minion data cache on the master. Any certificate signing request will be denied if minion_data_cache is disabled (it is enabled by default).

Note

Since grain values are controlled by minions, you should avoid using them to restrict certificate issuance.

See Is Targeting using Grain Data Secure?.

Changed in version 3007.0: Previously, a compound expression match was validated by the requesting minion itself via peer publishing, which did not protect from compromised minions. The new match validation takes place on the master using peer running.

Signing policies

In addition, the minion representing the CA needs to have at least one signing policy configured, remote calls not referencing one are always rejected.

The parameters specified in this signing policy override any parameters passed from the minion requesting the certificate. It can be configured in the CA minion's pillar, which takes precedence, or any location config.get looks up in. Signing policies are defined under x509_signing_policies.

You can restrict which minions can request a certificate under a configured signing policy by specifying a matcher in minions. This can be a glob or compound matcher (for the latter, see the notes above).

x509_signing_policies:
  www:
    - minions: 'www*'
    - signing_private_key: /etc/pki/ca.key
    - signing_cert: /etc/pki/ca.crt
    - C: US
    - ST: Utah
    - L: Salt Lake City
    - basicConstraints: "critical, CA:false"
    - keyUsage: "critical, cRLSign, keyCertSign"
    - subjectKeyIdentifier: hash
    - authorityKeyIdentifier: keyid,issuer:always
    - days_valid: 90
    - copypath: /etc/pki/issued_certs/

Note

The following semantics are applied regarding the order of preference for specifying the subject name:

  • If neither subject nor any name attributes (like CN) are part of the policy, issued certificates can contain any requested ones.

  • If any name attributes are specified in the signing policy, subject contained in requests is ignored.

  • If subject is specified in the signing policy, any name attributes are ignored. If the request contains the same data type for subject as the signing policy (for dicts and lists, and only then), merging is performed, otherwise subject is taken from the signing policy. Dicts are merged and list items are appended, with the items taken from the signing policy having priority.

Breaking changes versus the previous x509 modules

  • The output format has changed for all read_* functions as well as the state return dict.

  • The formatting of some extension definitions might have changed, but should be stable for most basic use cases.

  • The default ordering of RDNs/Name Attributes in the subject's Distinguished Name has been adapted to industry standards. This might cause a reissuance during the first state run.

  • For x509.private_key_managed, the file mode defaults to 0400. This should be considered a bug fix because writing private keys with world-readable permissions by default is a security issue.

  • Restricting signing policies using compound match expressions requires peer run permissions instead of peer publishing permissions:

# x509, x509_v2 in 3006.*
peer:
  ca_server:
    - match.compound

# x509_v2 from 3007.0 onwards
peer_run:
  ca_server:
    - match.compound_matches

Note that when a ca_server is involved, both peers must use the updated module version.

salt.modules.x509_v2.create_certificate(ca_server=None, signing_policy=None, encoding='pem', append_certs=None, pkcs12_passphrase=None, pkcs12_encryption_compat=False, pkcs12_friendlyname=None, path=None, overwrite=True, raw=False, **kwargs)

Create an X.509 certificate and return an encoded version of it.

Note

All parameters that take a public key, private key or certificate can be specified either as a PEM/hex/base64 string or a path to a local file encoded in all supported formats for the type.

CLI Example:

salt '*' x509.create_certificate signing_private_key='/etc/pki/myca.key' csr='/etc/pki/my.csr'
ca_server

Request a remotely signed certificate from ca_server. For this to work, a signing_policy must be specified, and that same policy must be configured on the ca_server. See Signing policies for details. Also, the Salt master must permit peers to call the sign_remote_certificate function, see Peer communication.

signing_policy

The name of a configured signing policy. Parameters specified in there are hardcoded and cannot be overridden. This is required for remote signing, otherwise optional. See Signing policies for details.

encoding

Specify the encoding of the resulting certificate. It can be returned as a pem (or pkcs7_pem) string or several (base64-encoded) binary formats (der, pkcs7_der, pkcs12). Defaults to pem.

append_certs

A list of additional certificates to append to the new one, e.g. to create a CA chain.

Note

Mind that when der encoding is in use, appending certificatees is prohibited.

copypath

Create a copy of the issued certificate in PEM format in this directory. The file will be named <serial_number>.crt if prepend_cn is False.

prepend_cn

When copypath is set, prepend the common name of the certificate to the file name like so: <CN>-<serial_number>.crt. Defaults to false.

pkcs12_passphrase

When encoding a certificate as pkcs12, encrypt it with this passphrase.

Note

PKCS12 encryption is very weak and should not be relied on for security.

pkcs12_encryption_compat

OpenSSL 3 and cryptography v37 switched to a much more secure default encryption for PKCS12, which might be incompatible with some systems. This forces the legacy encryption. Defaults to False.

pkcs12_friendlyname

When encoding a certificate as pkcs12, a name for the certificate can be included.

path

Instead of returning the certificate, write it to this file path.

overwrite

If path is specified and the file exists, overwrite it. Defaults to true.

raw

Return the encoded raw bytes instead of a string. Defaults to false.

digest

The hashing algorithm to use for the signature. Valid values are: sha1, sha224, sha256, sha384, sha512, sha512_224, sha512_256, sha3_224, sha3_256, sha3_384, sha3_512. Defaults to sha256. This will be ignored for ed25519 and ed448 key types.

private_key

The private key corresponding to the public key the certificate should be issued for. This is one way of specifying the public key that will be included in the certificate, the other ones being public_key and csr.

private_key_passphrase

If private_key is specified and encrypted, the passphrase to decrypt it.

public_key

The public key the certificate should be issued for. Other ways of passing the required information are private_key and csr. If neither are set, the public key of the signing_private_key will be included, i.e. a self-signed certificate is generated.

csr

A certificate signing request to use as a base for generating the certificate. The following information will be respected, depending on configuration: * public key * extensions, if not otherwise specified (arguments, signing_policy)

signing_cert

The CA certificate to be used for signing the issued certificate.

signing_private_key

The private key corresponding to the public key in signing_cert. Required.

signing_private_key_passphrase

If signing_private_key is encrypted, the passphrase to decrypt it.

serial_number

A serial number to be embedded in the certificate. If unspecified, will autogenerate one. This should be an integer, either in decimal or hexadecimal notation.

not_before

Set a specific date the certificate should not be valid before. The format should follow %Y-%m-%d %H:%M:%S and will be interpreted as GMT/UTC. Defaults to the time of issuance.

not_after

Set a specific date the certificate should not be valid after. The format should follow %Y-%m-%d %H:%M:%S and will be interpreted as GMT/UTC. If unspecified, defaults to the current time plus days_valid days.

days_valid

If not_after is unspecified, the number of days from the time of issuance the certificate should be valid for. Defaults to 30.

subject

The subject's distinguished name embedded in the certificate. This is one way of passing this information (see kwargs below for the other). This argument will be preferred and allows to control the order of RDNs in the DN as well as to embed RDNs with multiple attributes. This can be specified as an RFC4514-encoded string (CN=example.com,O=Example Inc,C=US, mind that the rendered order is reversed from what is embedded), a list of RDNs encoded as in RFC4514 (["C=US", "O=Example Inc", "CN=example.com"]) or a dictionary ({"CN": "example.com", "C": "US", "O": "Example Inc"}, default ordering). Multiple name attributes per RDN are concatenated with a +.

Note

Parsing of RFC4514 strings requires at least cryptography release 37.

kwargs

Embedded X.509v3 extensions and the subject's distinguished name can be controlled via supplemental keyword arguments. See the following for an overview.

Subject properties in kwargs

C, ST, L, STREET, O, OU, CN, MAIL, SN, GN, UID, SERIALNUMBER

X.509v3 extensions in kwargs

Most extensions can be configured using the same string format as OpenSSL, while some require adjustments. In general, since the strings are parsed to dicts/lists, you can always use the latter formats directly. Marking an extension as critical is done by including it at the beginning of the configuration string, in the list or as a key in the dictionary with the value true.

Examples (some showcase dict/list correspondance):

basicConstraints

critical, CA:TRUE, pathlen:1 or

- basicConstraints:
    critical: true
    ca: true
    pathlen: 1
keyUsage

critical, cRLSign, keyCertSign or

- keyUsage:
    - critical
    - cRLSign
    - keyCertSign
subjectKeyIdentifier

This can be an explicit value or hash, in which case the value will be set to the SHA1 hash of some encoding of the associated public key, depending on the underlying algorithm (RSA/ECDSA/EdDSA).

authorityKeyIdentifier

keyid:always, issuer

subjectAltName

There is support for all OpenSSL-defined types except otherName.

email:me@example.com,DNS:example.com or

# mind this being a list, not a dict
- subjectAltName:
    - email:me@example.com
    - DNS:example.com
issuerAltName

The syntax is the same as for subjectAltName, except that the additional value issuer:copy is supported, which will copy the values of subjectAltName in the issuer's certificate.

authorityInfoAccess

OCSP;URI:http://ocsp.example.com/,caIssuers;URI:http://myca.example.com/ca.cer

crlDistributionPoints

When set to a string value, items are interpreted as fullnames:

URI:http://example.com/myca.crl, URI:http://example.org/my.crl

There is also support for more attributes using the full form:

- crlDistributionPoints:
    - fullname: URI:http://example.com/myca.crl
      crlissuer: DNS:example.org
      reasons:
        - keyCompromise
    - URI:http://example.org/my.crl
certificatePolicies

critical, 1.2.4.5, 1.1.3.4

Again, there is support for more attributes using the full form:

- certificatePolicies:
    critical: true
    1.2.3.4.5: https://my.ca.com/pratice_statement
    1.2.4.5.6:
      - https://my.ca.com/pratice_statement
      - organization: myorg
        noticeNumbers: [1, 2, 3]
        text: mytext
policyConstraints

requireExplicitPolicy:3,inhibitPolicyMapping:1

inhibitAnyPolicy

The value is just an integer: - inhibitAnyPolicy: 1

nameConstraints

critical,permitted;IP:192.168.0.0/255.255.0.0,permitted;email:.example.com,excluded;email:.com

- nameConstraints:
    critical: true
    permitted:
      - IP:192.168.0.0/24
      - email:.example.com
    excluded:
      - email:.com
noCheck

This extension does not take any values, except critical. Just the presence in the keyword args will include it.

salt.modules.x509_v2.create_crl(signing_private_key, revoked, signing_cert=None, signing_private_key_passphrase=None, include_expired=False, days_valid=None, digest='sha256', encoding='pem', extensions=None, path=None, raw=False, **kwargs)

Create a certificate revocation list.

CLI Example:

salt '*' x509.create_crl signing_cert=/etc/pki/ca.crt                 signing_private_key=/etc/pki/ca.key                 revoked="[{'certificate': '/etc/pki/certs/www1.crt', 'revocation_date': '2015-03-01 00:00:00'}]"
signing_private_key

Your certificate authority's private key. It will be used to sign the CRL. Required.

revoked

A list of dicts containing all the certificates to revoke. Each dict represents one certificate. A dict must contain either the key serial_number with the value of the serial number to revoke, or certificate with some reference to the certificate to revoke.

The dict can optionally contain the revocation_date key. If this key is omitted, the revocation date will be set to now. It should be a string in the format "%Y-%m-%d %H:%M:%S".

The dict can also optionally contain the not_after key. This is redundant if the certificate key is included, since it will be sourced from the certificate. If the certificate key is not included, this can be used for the logic behind the include_expired parameter. It should be a string in the format "%Y-%m-%d %H:%M:%S".

The dict can also optionally contain the extensions key, which allows to set CRL entry-specific extensions. The following extensions are supported:

certificateIssuer

Identifies the certificate issuer associated with an entry in an indirect CRL. The format is the same as for subjectAltName.

CRLReason

Identifies the reason for certificate revocation. Available choices are unspecified, keyCompromise, CACompromise, affiliationChanged, superseded, cessationOfOperation, certificateHold, privilegeWithdrawn, aACompromise and removeFromCRL.

invalidityDate

include_expired

Also include already expired certificates in the CRL. Defaults to false.

days_valid

encoding

Specify the encoding of the resulting certificate revocation list. It can be returned as a pem string or base64-encoded der. Defaults to pem.

extensions

Add CRL extensions. The following are available:

See x509.create_certificate.

cRLNumber

Specifies a sequential number for each CRL issued by a CA. Values must be integers.

deltaCRLIndicator

If the CRL is a delta CRL, this value points to the cRLNumber of the base cRL. Values must be integers.

freshestCRL

Identifies how delta CRL information is obtained. The format is the same as crlDistributionPoints.

issuerAltName

See x509.create_certificate.

issuingDistributionPoint

Identifies the CRL distribution point for a particular CRL and indicates what kinds of revocation it covers. The format is comparable to crlDistributionPoints. Specify as follows:

issuingDistributionPoint:
  fullname:  # or relativename with RDN
    - URI:http://example.com/myca.crl
  onlysomereasons:
    - keyCompromise
  onlyuser: true
  onlyCA: true
  onlyAA: true
  indirectCRL: false
path

Instead of returning the CRL, write it to this file path.

raw

pkcs12_encryption_compat

Some operating systems are incompatible with the encryption defaults for PKCS12 used since OpenSSL v3. This switch triggers a fallback to PBESv1SHA1And3KeyTripleDESCBC. Please consider the notes on PKCS12 encryption.

path

Instead of returning the private key, write it to this file path. Note that this does not use safe permissions and should be avoided.

raw

Return the encoded raw bytes instead of a string. Defaults to false.

salt '*' x509.verify_private_key /etc/pki/my.key /etc/pki/my.crt
private_key

The private key to check.

public_key

The certificate (or any reference that can be passed to get_public_key) to retrieve the public key from.

passphrase

If private_key is encrypted, the passphrase to decrypt it.

salt.modules.x509_v2.verify_signature(certificate, signing_pub_key=None, signing_pub_key_passphrase=None)

Verify that a signature on a certificate was made by the private key corresponding to the public key associated with the specified certificate.

CLI Example:

salt '*' x509.verify_signature /etc/pki/my.key /etc/pki/my.crt
certificate

The certificate to check the signature on.

signing_pub_key

Any reference that can be passed to get_public_key to retrieve the public key of the signing entity from. If unspecified, will take the public key of certificate, i.e. verify a self-signed certificate.

signing_pub_key_passphrase

If signing_pub_key is encrypted, the passphrase to decrypt it.

salt.modules.x509_v2.will_expire(certificate, days)

Returns a dict containing details of a certificate and whether the certificate will expire in the specified number of days.

CLI Example:

salt '*' x509.will_expire "/etc/pki/mycert.crt" days=30
certificate

The certificate to check.

days

The number of days in the future to check the validity for.

salt.modules.x509_v2.write_pem(text, path, overwrite=True, pem_type=None)

Writes out a PEM string, fixing any formatting or whitespace issues before writing.

CLI Example:

salt '*' x509.write_pem "-----BEGIN CERTIFICATE-----MIIGMzCCBBugA..." path=/etc/pki/mycert.crt
text

PEM string input to be written out.

path

Path of the file to write the PEM out to.

overwrite

If True (default), write_pem will overwrite the entire PEM file. Set to False to preserve existing private keys and DH params that may exist in the PEM file.

pem_type

The PEM type to be saved, for example CERTIFICATE or PUBLIC KEY. Adding this will allow the function to take input that may contain multiple PEM types.
