Functions ¶
func DecryptBase64String ¶ added in v0.2.0
DecryptBase64String decrypts ciphertext in base64 form to plaintext by receiver private key
func DecryptHexString ¶ added in v0.2.0
DecryptHexString decrypts ciphertext in hex form to plaintext by receiver private key
func EncryptStringToBase64 ¶ added in v0.2.0
EncryptStringToBase64 encrypts plaintext to ciphertext in base64 form using receiver public key
Types ¶
type ECDH ¶ added in v0.2.0
type ECDH func(priv *PrivateKey, pub *PublicKey) (masterSecret []byte)
ECDH calculates a master secret from a private key & a public key. Its output will be passed to a KDF for deriving the encryption key.
type PrivateKey ¶
type PrivateKey struct {
Pub *PublicKey
// contains filtered or unexported fields
}
