This is a purposely less comprehensive check than RequestMatchesSpec as some issuers override/force certain fields.

Deprecated: This function is very fuzzy and makes too many assumptions about how the issuer maps a CSR to a certificate. We only keep it for backward compatibility reasons, but use other comparison functions when possible.

This is to mitigate a potential attack against x509 certificates that use a predictable serial number and weak MD5 hashing algorithms. In practice, this shouldn't really be a concern anyway.

func GeneratePrivateKeyForCertificate 

func GeneratePrivateKeyForCertificate(crt *v1.Certificate) (crypto.Signer, error)

GeneratePrivateKeyForCertificate will generate a private key suitable for the provided cert-manager Certificate resource, taking into account the parameters on the provided resource. The returned key will either be RSA or ECDSA.

RSA, Ed25519 and ECDSA private keys are supported. The function panics if the CertificateSpec contains an unknown key algorithm, since this should have been caught by the CertificateSpec validation already.

If renewBefore is non-nil and less than the certificate's lifetime, renewal time will be the computed renewBefore period before expiry. If renewBeforePercentage is non-nil and in the range (0,100), renewal time will be the computed period before expiry based on the renewBeforePercentage and actualDuration values. Default is 2/3 through certificate's lifetime.

func RenewalTime added in v1.12.0 

func RenewalTime(notBefore, notAfter time.Time, renewBefore *metav1.Duration, renewBeforePercentage *int32) *metav1.Time

ParseSingleCertificateChain returns the PEM-encoded chain of certificates as well as the PEM-encoded CA certificate.

The CA (CAPEM) may not be a true root, but the highest intermediate certificate. The certificate is chosen as follows:

  • If the chain has a self-signed root, the root certificate.
  • If the chain has no self-signed root and has > 1 certificates, the highest certificate in the chain.
  • If the chain has no self-signed root and has == 1 certificate, nil.

The certificate chain (ChainPEM) starts with the leaf certificate and ends with the highest certificate in the chain which is not self-signed. Self-signed certificates are not included in the chain because we are certain they are known and trusted by the client already.

This function removes duplicate certificate entries as well as comments and unnecessary white space.

An error is returned if the passed bundle is not a valid single chain, the bundle is malformed, or the chain is broken.
