代码如下:
(ql:quickload :ironclad)
(ql:quickload :crypto-shortcuts)
(use-package :ironclad)
(defparameter str "Hello World!")
(defparameter message (ascii-string-to-byte-array str))
(defparameter key "1234")
(let ((cipher (make-cipher :arcfour
:key (ascii-string-to-byte-array key)
:mode :stream
:initialization-vector (make-random-salt)))
(text
(ascii-string-to-byte-array
(cryptos:to-base64 (copy-seq message)))))
;; #(83 71 86 115 98 71 56 103 86 50 57 121 98 71 81 104)
(format t "~a~%" text)
(encrypt-in-place cipher text)
;; #(86 14 39 220 145 171 63 106 89 41 57 41 135 32 85 188)
;; "Vg4n3JGrP2pZKTkphyBVvA=="
(format t "~a~%" text)
(format t "~a~%" (cryptos:to-base64 text))
(decrypt-in-place cipher text)
;; ?
;; #(83 71 86 115 98 71 56 103 86 50 57 121 98 71 81 104)
(format t "~a~%" text))
我的代码有什么问题?
after (decrypt-in-place cipher text)
,text
应该和原来的一样,但事实并非如此。为什么?
谁能帮忙?
以下是加密快捷方式版本:
(cryptos:decrypt (cryptos:encrypt str
key
:cipher :arcfour
:mode :stream)
key
:cipher :arcfour
:mode :stream)
一切都好。
