Functions ¶

func DecryptAes256Gcm ¶

func DecryptAes256Gcm(data, masterKey, salt []byte) ([]byte, error)

DecryptAes256Gcm encrypts data with AES 256 GCM.

func DeriveKeyFromMasterKey ¶

func DeriveKeyFromMasterKey(masterKey, salt, purpose []byte, length int) []byte

DeriveKeyFromMasterKey computes a key for a specific purpose and length using HKDF based on the master key.

func DeriveKeyFromPassword ¶

func DeriveKeyFromPassword(password string, salt []byte, algorithm string) ([]byte, error)

DeriveKeyFromPassword derives encryption key using the provided password and per-repository unique ID.

func EncryptAes256Gcm ¶

func EncryptAes256Gcm(data, masterKey, salt []byte) ([]byte, error)

EncryptAes256Gcm encrypts data with AES 256 GCM.

func RegisterKeyDerivationFunc ¶ added in v0.16.0

func RegisterKeyDerivationFunc(name string, keyDeriver keyDerivationFunc)

RegisterKeyDerivationFunc registers various key derivation functions.
