Arguments: encrypted &key key end context (pad t) string in-place (external-format :utf-8) (mode :ecb) iv

Blowfish is an old cipher, designed in 1993. We recommend it not be used, because it is susceptible to various attacks and is no longer considered secure. We maintain support to allow for encrypted material to be decrypted.

This function decrypts encrypted, which should be an (unsigned-byte 8) array returned by a call to blowfish-encrypt.

This function returns one or two values, as the string keyword argument is true or false. If string is true, a string is returned as the only returned value. If string is false, an (unsigned-byte 8) array representing the decryption and an integer specifying how many bytes there are in the decrypted result are returned. The second returned value is the length of the array returned as the first returned value when the in-place keyword argument is false, and is a value less than or equal to the length when in-place is true.

The arguments are:

See also blowfish-encrypt and blowfish-init.

See also the new auxilliary functions hex-string-to-usb8-array and usb8-array-to-hex-string.

See Support for Blowfish encryption in miscellaneous.htm for information on Blowfish encryption and Blowfish encryption support in Allegro CL. There are examples of blowfish encryption and decryption in that section. Support for encryption in the same document discusses encryption support in Allegro CL in general.
