Types ¶

type Algorithm ¶

type Algorithm int

Algorithm defines the signature algorithm.

const (
	AlgorithmPS256 Algorithm = 1 + iota // RSASSA-PSS with SHA-256
	AlgorithmPS384                      // RSASSA-PSS with SHA-384
	AlgorithmPS512                      // RSASSA-PSS with SHA-512
	AlgorithmES256                      // ECDSA on secp256r1 with SHA-256
	AlgorithmES384                      // ECDSA on secp384r1 with SHA-384
	AlgorithmES512                      // ECDSA on secp521r1 with SHA-512
)

Signature algorithms supported by this library.

func (Algorithm) Hash ¶

func (alg Algorithm) Hash() crypto.Hash

Hash returns the hash function of the algorithm.

type KeySpec ¶

type KeySpec struct {
	// KeyType is the type of the key.
	Type KeyType

	// KeySize is the size of the key in bits.
	Size int
}

KeySpec defines a key type and size.

func ExtractKeySpec ¶

func ExtractKeySpec(signingCert *x509.Certificate) (KeySpec, error)

ExtractKeySpec extracts KeySpec from the signing certificate.

func (KeySpec) SignatureAlgorithm ¶

func (k KeySpec) SignatureAlgorithm() Algorithm

SignatureAlgorithm returns the signing algorithm associated with the KeySpec.

type KeyType ¶

type KeyType int

KeyType defines the key type.

const (
	KeyTypeRSA KeyType = 1 + iota // KeyType RSA
	KeyTypeEC                     // KeyType EC
)
