Functions

func Decrypt

func Decrypt(key, encrypted []byte) ([]byte, error)

Decrypt performs AES-256 GCM decryption with a given 32-bytes key.

func DecryptWithRSA

func DecryptWithRSA(encrypted, privKey, password []byte) ([]byte, error)

DecryptWithRSA decrypts the given encrypted data with RSA-OAEP. privKey must be a RSA private key in PEM or DER format.

func DeriveKey

func DeriveKey(password string, salt []byte) []byte

func Encrypt

func Encrypt(key, plaintext []byte) ([]byte, error)

Encrypt performs AES-256 GCM encryption with a given 32-bytes key.

func EncryptWithRSA

func EncryptWithRSA(plaintext, pubKey []byte) ([]byte, error)

EncryptWithRSA encrypts the given data with RSA-OAEP. pubKey must be a RSA public key in PEM or DER format.

Types

type GPG

type GPG interface {
	// EncryptWithRecipient encrypts a given plaintext using a given user's public-key.
	EncryptWithRecipient(ctx context.Context, plaintext []byte, userID string) ([]byte, error)
	// DecryptWithRecipient decrypts a given encrypted data using a given user's private-key.
	DecryptWithRecipient(ctx context.Context, encrypted []byte, userID string) ([]byte, error)
}

GPG works as a GPG client.

func NewGPG

func NewGPG(executable string) GPG
