Types

type KeyPair

type KeyPair struct {
	// contains filtered or unexported fields
}

KeyPair for RSA : Bencrypt Implementation of a RSA-4096,AES-CBC-256,HMAC-SHA-256 system

func (*KeyPair) Clone

func (r *KeyPair) Clone() bc.KeyPair

Clone : Returns a new node of the same type as this one

func (*KeyPair) DecryptMessage

func (r *KeyPair) DecryptMessage(data []byte) (bool, []byte, error)

DecryptMessage : Decrypts a message 1) PEM decode header and body 2) decrypt header 3) verify the header signature 4) verify the msg signature 5) decrypt the msg

func (*KeyPair) EncryptMessage

func (r *KeyPair) EncryptMessage(clear []byte, pubkey bc.PubKey) ([]byte, error)

EncryptMessage : Encrypts a message

1. generate aes key (32 random bytes)
2. encrypt the message with aes key
3. sha256 the encrypted message
4. sha256 the key and msg hash
5. encrypt the header with rsa
6. PEM encode encrypted header and encrypted message -> return
