Functions

func DeriveKey

func DeriveKey(secret []byte) ([]byte, error)

DeriveKey derives a key as PBKDF2 from the specified secret string. HMAC is SHA 256, salt a random 16 bytes array, 2048 iterations. The returned key length is 32 bytes

func NewEncryptionKey

func NewEncryptionKey() ([]byte, error)

NewEncryptionKey generates a random 256-bit key for Encrypt() and Decrypt(). It panics if the source of randomness fails.

func NewSalt

func NewSalt(secret []byte) ([]byte, error)

NewSalt create pseudo random binary data (salt) that is used as an additional input to derive the encryption key.
