Functions ¶

func EVPBytesToKey ¶

func EVPBytesToKey(password string, keyLen int) (key []byte)

func MD5Sum ¶

func MD5Sum(d []byte) []byte

func NewGcm ¶

func NewGcm(key []byte) (cipher.AEAD, error)

func NewPC20P1305 ¶ added in v0.1.3

func NewPC20P1305(key []byte) (smaead.PartialAEAD, error)

func NewPGcm ¶ added in v0.1.3

func NewPGcm(key []byte) (smaead.PartialAEAD, error)

Types ¶

type CipherConf ¶

type CipherConf struct {
	KeyLen           int
	SaltLen          int
	NonceLen         int
	TagLen           int
	NewCipher        func(key []byte) (cipher.AEAD, error)
	NewPartialCipher func(key []byte) (smaead.PartialAEAD, error)
}

func (*CipherConf) UnsafeVerifyATyp ¶ added in v0.1.3

func (conf *CipherConf) UnsafeVerifyATyp(buf []byte, masterKey []byte, salt []byte, cipherText []byte, subKey *[]byte) bool

Warning: UnsafeVerifyATyp brings less than 25% performance improvement in most cases. It is dangerous and NOT recommended. Do not use it if you feel unnecessary.

func (*CipherConf) Verify ¶

func (conf *CipherConf) Verify(buf []byte, masterKey []byte, salt []byte, cipherText []byte, subKey *[]byte) ([]byte, bool)
