一个用移位思想实现的简单数据加密程序，因为不论是大写还是小写字母,其ASC码值都是按顺序排列的.故可以用相对应的ASC码值进行判断以及算法实现.-a shift ideology with a simple data encryption procedures, because both uppercase or lowercase letters, the value of ASC codes are arranged in chronological order according to the. It can be used to be the relative value of ASC code of judgment and algorithm.

Base64 加密算法（Author 蒋柏良 Jerry Jiang)
Base64 加密算法（Author 蒋柏良 Jerry Jiang)-*
* DESCRIPTION
* Base64 processes input in 24bit chunks by converting each chunk into 4
* bytes of output. It does so by splitting input into four 6bit groups and
* using these as indexes in the following substitution table-
* const char base64_map[] =
* "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
* "abcdefghijklmnopqrstuvwxyz"
* "0123456789+/"
* If an input is not a multiple of 3 bytes, it s padded with zeros. In
* this case the output bytes that consist entirely of the pad data are
* replaced with = .
*
* Example
* An input of 0x00 0x45 0xF2 is equivalent to 00000000 01000101 11110010
* bit sequence, which s then split into 000000 000100 010111 110010
* and these are substituted to produce the following base64 encoding
* A E X y
*
* RETURN VALUE
* b64_length() should return output length for the input of len bytes.
* b64_encode() should encode len bytes from src int

这两个工程主要用CSP
1、CSPTEST 写的比较乱 主要是给当时一个朋友做参考调用的 完成非对称密钥的生成、导入、导出、加密、解密、对称的加密解密、签名、验证。
2、CSTTEST2 写的比前个好些，但是平时上班，下班自己也要写论文，所以花的时间也不太多，很多地方都偷懒了。比如文件大小我没有用NEW 而且指定了1024 有需要的朋友可以自己修改。这个工程主要是非对称的密钥的导出和导入，还有就是会话密钥的操作。-these two works mainly with a CSP. CSPTEST comparison was made mainly to the chaos when a friend called to refer to the completion of the non-symmetric key generation, importing and exporting, encryption, decryption, symmetric encryption and decryption, signature, the certification. 2, CSTTEST2 write better than in the previous months, but usually go to work and finish their own toilet paper so I spent the time is not too much, all of the lazy. For instance, file size I have not used the NEW 1024 and designated a need to amend their friends. The project mainly non-symmetric keys to the Export and Import, there is the session key operation.

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.
