Tôi đang gặp vấn đề liên 泉 đến Encryption.Decryption sử dụng thuật toán mã hóa DES

几个密码算法的源代码，不知道有了没有~~ 下的人多了就继续上传-Some source programs of encryption arithmetic.I don t know whether it is always existed or not.I will upload it if a lot of people have downloaded.

计算文件hash值的源代码，包含crc,md2,md4,md5,sha,sha1,sha256,ra-Calculated hash value of document

SHA-1Hash函数源码，可以对任何文件做Hash，得到的Hash值为160位。具有抗强碰撞，弱碰撞等能力。虽然王小云已经找到了个别碰撞。但在新的好的hash函数出来之前仍将被广泛使用。-SHA-1Hash function source, any document can be done right hash, the hash value of 160. Anti-collision, the weak capabilities of the collision. Although Bruce Schneier, had found individual collisions. But the new good hash function will be out before widespread use.

crc32加密算法，希望对大家有帮助，多多支持-CRC32

base64 算法，这是一个非常详细的编码和解码的过程-base64 algorithm, this is a very detailed process of encoding and decoding

EXELOCK 1.83 EXE文件加密器的源代码-EXELOCK 1.83 EXE file encryption for the source code

一些常用编码，加密算法的c/c++代码，包括，base64,sha1,des,md5等-Some commonly used encoding, encryption algorithm c/c++ Code, including, base64, sha1, des, md5, etc.

Openssl的常用头文件，本人经常用，很不错的。-The daily head file of Openssl, I often use, it is very good.

C语言环境下的AES加密算法，支持128位的AES加密。-C language environment AES encryption algorithm, support 128-bit AES encryption.

一个用C＋＋、JAVA、C#等编写的数字签名代码序列，里面有三种不同语言写的-A use of C , JAVA, C# Such the preparation of the digital signature code sequence, which has three different written languages
