Types ¶
type Boxer ¶
type Boxer struct {
// contains filtered or unexported fields
}
func (*Boxer) Decrypt ¶
func (bxr *Boxer) Decrypt(ctxt []byte, author refs.FeedRef, prev refs.MessageRef, candidates []keys.Recipient) ([]byte, error)
Decrypt takes the ciphertext, it's auther and the previous hash of the message and some canddiates to try to decrypt with. It returns the decrypted cleartext or an error.
func (*Boxer) Encrypt ¶
func (bxr *Boxer) Encrypt(plain []byte, author refs.FeedRef, prev refs.MessageRef, recpts []keys.Recipient) ([]byte, error)
Encrypt takes a buffer to write into (out), the plaintext to encrypt, the (author) of the message, her (prev)ious message hash and a list of recipients (recpts). If out is too small to hold the full message, additonal allocations will be made. The ciphertext is returned as the first return value.
