[Other] cryptfial DL : 0: 文本串加密和解密程序。一个文本串可用事先给定的字母映射表进行加密。例如，设字母映射表为：　　　　a b c d e f g h I j k l m n o p q r s t u v w x y z 　　　　n g z q t c o b m u h e l k p d a w x f y I v r s j 　　　　则字符串“encrypt”被加密为“tkzwsdf”。试写一个算法将输入的文本串进行加密后输出；另写一个算法将输入的已加密的文本串进行解密后输出。-Text string encryption and decryption process. Available in advance of a text string given letter mapping table is encrypted. For example, suppose the letter mapping table: abcdefgh I jklmnopqrstuvwxyz ngzqtcobmuhelkpdawxfy I vrsj the string " encrypt" is encrypted as " tkzwsdf" . Try to write an algorithm to input text string will be encrypted output another write encrypted text string entered an algorithm will be decrypted output.

[Other] Encryption DL : 0: ASCII表中英文字符加密,加密方法为从输入框输入加密字符然后进行算法上的进制加密，中途加密方法在源码中已说明，不为纯粹加密，附加了防破解的操作在内，被加密后文字可查看，但无翻译方法情况下无法解密-ASCII table in the English character encryption, encryption method for the input the input box to encrypt the characters and then the algorithm on the encryption, the way the encryption method has been described in the source, not for the pure encryption, with anti-crack operation, including encryption After the text can be viewed, but no translation method can not be decrypted

[Other] delphi001 DL : 0: In the continuation of the topic of cryptography, we show you the source code that encrypts the source text using the DES algorithm. By the way Data Encryption Standard (DES), intended for use in government and government agencies in the United States. DES encrypts 64-bit data blocks using a 56-bit key. Decryption in DES is an operation of reverse encryption and is performed by repeating encryption operations in the reverse order.
