这个是MD5算法C的源代码，希望对大家有用-This is the MD5 algorithm C source code, in the hope that useful to everybody

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.

C++下的base64编码，能够支持任何数据进行base64编码。 -C++ Under the base64 encoding, can support any data base64 encoding.

My stuff is aimed at teaching, not efficiency. The others are probably much better implementations. The last one has both C++ and Java versions where my stuff is all C. So lots of choices!
