Functions

func CheckSignature

func CheckSignature(csr *x509.CertificateRequest, algo x509.SignatureAlgorithm, signed, signature []byte) error

CheckSignature verifies a signature made by the key on a CSR, such as on the CSR itself.

func ExpiryTime

func ExpiryTime(chain []*x509.Certificate) *time.Time

ExpiryTime returns the time when the certificate chain is expired.

func GetKeyDERFromPEM

func GetKeyDERFromPEM(in []byte) ([]byte, error)

GetKeyDERFromPEM parses a PEM-encoded private key and returns DER-format key bytes.

func HashAlgoString

func HashAlgoString(alg x509.SignatureAlgorithm) string

HashAlgoString returns the hash algorithm name contains in the signature method.

func InclusiveDate

func InclusiveDate(year int, month time.Month, day int) time.Time

InclusiveDate returns the time.Time representation of a date - 1 nanosecond. This allows time.After to be used inclusively.

func KeyLength

func KeyLength(key interface{}) int

KeyLength returns the bit size of ECDSA or RSA PublicKey

func MonthsValid

func MonthsValid(c *x509.Certificate) int

MonthsValid returns the number of months for which a certificate is valid.

func ParseCSR

func ParseCSR(in []byte) (csr *x509.CertificateRequest, rest []byte, err error)

ParseCSR parses a PEM- or DER-encoded PKCS #10 certificate signing request.

func ParseCertificatePEM

func ParseCertificatePEM(certPEM []byte) (*x509.Certificate, error)

ParseCertificatePEM parses and returns a PEM-encoded certificate, can handle PEM encoded PKCS #7 structures.

func ParseCertificatesDER

func ParseCertificatesDER(certsDER []byte, password string) ([]*x509.Certificate, crypto.Signer, error)

ParseCertificatesDER parses a DER encoding of a certificate object and possibly private key, either PKCS #7, PKCS #12, or raw x509.

func ParseCertificatesPEM

func ParseCertificatesPEM(certsPEM []byte) ([]*x509.Certificate, error)

ParseCertificatesPEM parses a sequence of PEM-encoded certificate and returns them, can handle PEM encoded PKCS #7 structures.

func ParseOneCertificateFromPEM

func ParseOneCertificateFromPEM(certsPEM []byte) ([]*x509.Certificate, []byte, error)

ParseOneCertificateFromPEM attempts to parse one PEM encoded certificate object, either a raw x509 certificate or a PKCS #7 structure possibly containing multiple certificates, from the top of certsPEM, which itself may contain multiple PEM encoded certificate objects.

func ParsePrivateKeyPEM

func ParsePrivateKeyPEM(keyPEM []byte) (key crypto.Signer, err error)

ParsePrivateKeyPEM parses and returns a PEM-encoded private key. The private key may be either an unencrypted PKCS#8, PKCS#1, or elliptic private key.

func ParseSelfSignedCertificatePEM

func ParseSelfSignedCertificatePEM(certPEM []byte) (*x509.Certificate, error)

ParseSelfSignedCertificatePEM parses a PEM-encoded certificate and check if it is self-signed.

func SignatureString

func SignatureString(alg x509.SignatureAlgorithm) string

SignatureString returns the TLS signature string corresponding to an X509 signature algorithm.

func SignerAlgo

func SignerAlgo(priv crypto.Signer, h crypto.Hash) x509.SignatureAlgorithm

SignerAlgo returns an X.509 signature algorithm corresponding to the crypto.Hash provided from a crypto.Signer.

func ValidExpiry

func ValidExpiry(c *x509.Certificate) bool

ValidExpiry determines if a certificate is valid for an acceptable length of time per the CA/Browser Forum baseline requirements. See https://cabforum.org/wp-content/uploads/CAB-Forum-BR-1.3.0.pdf
