fn expand_key #
fn expand_key(key []u8, mut bf Blowfish)
expand_key performs a key expansion on the given Blowfish cipher.
fn expand_key_with_salt #
fn expand_key_with_salt(key []u8, salt []u8, mut bf Blowfish)
expand_key_with_salt using salt to expand the key.
fn new_cipher #
fn new_cipher(key []u8) !Blowfish
new_cipher creates and returns a new Blowfish cipher. The key argument should be the Blowfish key, from 1 to 56 bytes.
fn new_salted_cipher #
fn new_salted_cipher(key []u8, salt []u8) !Blowfish
new_salted_cipher returns a new Blowfish cipher that folds a salt into its key schedule.
struct Blowfish #
struct Blowfish {
pub mut:
p [18]u32
s [4][256]u32
}
fn (Blowfish) encrypt #
fn (mut bf Blowfish) encrypt(mut dst []u8, src []u8)
encrypt encrypts the 8-byte buffer src using the key k and stores the result in dst.
