java加密技术：除了DES，我们还知道有DESede（TripleDES，就是3DES）、AES、Blowfish、RC2、RC4（ARCFOUR）等多种对称加密方式，其实现方式大同小异，这里介绍对称加密的另一个算法——PBE-java encryption technology: In addition to DES, we also know DESede (TripleDES, that is, 3DES), AES, Blowfish, RC2, RC4 (ARCFOUR) and other symmetric encryption methods, the means to achieve similar, here' s another symmetric encryption algorithm--PBE
