Fish
Fish is a Go implementation for IRC FiSH encryption. It uses the Blowfish cipher to encrypt/decrypt messages in EBC and CBC modes based on a symmetric key.
It calls ciphers from the Go standard library and sub-repositories, handles base64 encoding and irc message parsing.
The EBC implementation is based off the original FiSH-irssi source, see BASE64.md for an explanation of the unique base64 encoding scheme.
The CBC implementation is based off the extension of FiSH-irssi by falsovsky for compatibility with mircryption.
To use CBC mode the key must be prepended with cbc:

Types ¶
type Fish ¶
type Fish struct {
// contains filtered or unexported fields
}
Fish is an IRC Blowfish encryption cipher using a specific key and block mode.
func NewFish ¶
NewFish creates and returns a Fish for the specified key. To use CBC block mode the key must be prepended with "cbc:". Fails if the key is invalid.
func (*Fish) Decrypt ¶
Decrypt decrypts the specified msg and returns it. Fails for CBC mode if the decrypted string cannot be decoded.
