Functions

func FromHash

func FromHash(alg crypto.Hash) (asn1.ObjectIdentifier, error)

FromHash returns corresponding ASN.1 OID for the given Hash algorithm.

func ToHash

func ToHash(alg asn1.ObjectIdentifier) (crypto.Hash, bool)

ToHash converts ASN.1 digest algorithm identifier to golang crypto hash if it is available.

func ToSignatureAlgorithm

func ToSignatureAlgorithm(digestAlg, sigAlg asn1.ObjectIdentifier) x509.SignatureAlgorithm

ToSignatureAlgorithm converts ASN.1 digest and signature algorithm identifiers to golang signature algorithms.
