Functions

func MustDecryptAES

func MustDecryptAES(key, ciphertext string) string

MustDecryptAES decrypts a ciphertext encrypted by MustEncryptAES. The key must consist of 32 bytes, hex-encoded. The ciphertext must be base64-encoded, prefixed with "enc:".

func MustEncryptAES

func MustEncryptAES(key, plaintext string) string

MustEncryptAES encrypts the given plaintext using symmetric AES, GCM mode. The key must consist of 32 bytes, hex-encoded. The ciphertext will be base64-encoded, prefixed with "enc:".

func MustGenerateRandomAESKey

func MustGenerateRandomAESKey() string

MustGenerateRandomAESKey generates a random AES key.

func MustPEMToRSAPrivateKey

func MustPEMToRSAPrivateKey(buf []byte) *rsa.PrivateKey

MustPEMToRSAPrivateKey is like PEMToRSAPrivateKey but panics on error.

func MustPEMToRSAPublicKey

func MustPEMToRSAPublicKey(buf []byte) *rsa.PublicKey

MustPEMToRSAPublicKey is like PEMToRSAPublicKey but panics on error.

func PEMToRSAPrivateKey

func PEMToRSAPrivateKey(buf []byte) (*rsa.PrivateKey, error)

PEMToRSAPrivateKey tries to find and parse a *rsa.PrivateKey in the given PEM file.

func PEMToRSAPublicKey

func PEMToRSAPublicKey(buf []byte) (*rsa.PublicKey, error)

PEMToRSAPublicKey tries to find and parse a *rsa.PublicKey in the given PEM file.

func RSAPrivateKeyToPEM

func RSAPrivateKeyToPEM(key *rsa.PrivateKey) []byte

RSAPrivateKeyToPEM encodes a *rsa.PrivateKey to PEM format.

func RSAPublicKeyToPEM

func RSAPublicKeyToPEM(key *rsa.PublicKey) []byte

RSAPublicKeyToPEM encodes a *rsa.PublicKey to PEM format.
