用Caesar算法实现文本加密的程序

使用VB写的加密算法库，包括Blowfish, IDEA, Triple DES (3DES), DES, DESE, Gost, Skipjack, TEA, Cast5, Serpent-128, Serpent-192, Serpent-256, Rijndael-128, Rijndael-192, Rijndael-256, RC2, RC4, and Twofish), six popular hash algorithms (SHA-1, SHA-256, MD2, MD4, MD5, and RipeMD), 还有 Huffman和Base64算法.- Uses encryption algorithm storehouse which VB writes, including Blowfish, IDEA, Triple DES (3DES), DES, DESE, Gost, Skipjack, TEA, Cast5, Serpent-128, Serpent-192, Serpent-256, Rijndael-128, Rijndael-192, Rijndael-256, RC2, RC4, and Twofish), six popular hash algorithms (SHA-1, SHA-256, MD2, MD4, MD5, and RipeMD), but also has Huffman and the Base64 algorithm

MD5算法，vb编写，纯手工无私奉献，极力推荐下载！复制粘贴可直接使用！调用函数直接是MD5（），简单易懂，不可逆！

128位(或192或256bit该代码以128为例)的密钥长度和分组长度，数据分组（输入的明文），先进行逐比特异或（AddRoundKey） 运算。然后通过循环十次非线性代换（SubBytes）、行变换（ShiftRows）、列变换（MixColumns）、逐比特异或【最后一轮不进行列变换】 的过程，输出128位（或192或256bit）数据即是密文。这就是加密过程。之后进行之前的逆过程，即可得到明文，此为解密过程。
