Functions

func CreateSecretKey

func CreateSecretKey(version Version) ([]byte, error)

CreateSecretKey creates a secret key that can be used with the functions EncryptWithKey(), DecryptWithKey(), and VerifyWithKey().

func DecryptWithKey

func DecryptWithKey(key, data []byte) ([]byte, error)

DecryptWithKey decrypts data with the given secret key.

func DecryptWithPassword

func DecryptWithPassword(password, data []byte) ([]byte, error)

DecryptWithPassword decrypts data with the given password.

func EncryptWithKey

func EncryptWithKey(key, data []byte, version Version) ([]byte, error)

EncryptWithKey encrypts data with the given secret key and version.

func EncryptWithPassword

func EncryptWithPassword(password, data []byte, version Version) ([]byte, error)

EncryptWithPassword encrypts data with the given password and version.

func VerifyWithKey

func VerifyWithKey(key, data []byte) bool

VerifyWithKey verifies data with the given secret key.

func VerifyWithPassword

func VerifyWithPassword(password, data []byte) bool

VerifyWithPasswordverifies verifies data with the given password.
