kana-hash

Common Lisp kana hashes using CFFI.

We export one function, make-hash, that takes the string we want to hash, and optionally the algorithm, salt-type and salt to use.

Installation

• git clone the repo
• $ make && sudo make install
• Add kana-hash to your quicklisp local-projects with something like $ ln -sf `pwd`/contrib/kana-hash/ $home/quicklisp/local-projects/kana-hash
• Then in your Lisp do:

(ql:register-local-projects)
(ql:quickload :kana-hash)

Usage

;; Just hashing the string
(kana-hash:make-hash "uguu~")

;; Using a different algorithm
(kana-hash:make-hash "uguu~" :algo +algo-sha256+)

;; Using a salt
;; salt-type is implicitly set to +salt-specific+
(kana-hash:make-hash "uguu~" :salt "am I cute?")

;; Using a different algorithm and salt-type
(kana-hash:make-hash "uguu~"
                     :algo +algo-crc32+
                     :salt-type +salt-random+)

Algorithms

We define lisp constants for the algorithms used. Input is uguu~ using the default salt.

Algorithm	Output
+algo-sha256+	おシソまツアでぅせヅモァだゅノぴヲろヂォセづマふげぁユねハァがゅ
+algo-crc32+	わほヂァ
+algo-crc64+	づやワえほぢレご
+algo-sha256-truncated+	おシソまツアでぅ

Salt types

We also define constants for salt types. Input is uguu~ using the default algorithm.

Salt Type	Output
+salt-none+	らニにすわムねぅ
+salt-default+	おシソまツアでぅ
+salt-specific+	ぱペみぇサべツュ
+salt-random+	リヨみがゆヲえに

Calling +salt-specific+ without a salt it will use the salt NIL. Using a salt will implicitly set salt-type to +salt-specific+.
