Web1 对称加密对称加密就是使用同一把密钥加密、解密。对称加密由于加和解密使用的是同一个密钥算法，故而在加解密的过程中速度比较快。 常用的对称加密算法有 AES、DES、3DES、TDEA、Blowfish、RC2、RC4 和 RC5 等。 WebSecond, note that base64 character represents 6 bits. This mean that the first 4 base64 characters encodes the first 3 bytes of plaintext, i.e, the 3 first characters (since 4*6 = 3*8). The next 4 base64 characters will then encode the next 3 characters of plaintext and so on. Using this observation it is easy to do frequency analysis.
