Java 常用加密算法(二)---对称加密(DES/3DES(TripleDES)/AES)

基于“对称密钥”的加密算法主要有DES、3DES（TripleDES）、AES、RC2、RC4、RC5和Blowfish等。代码中用到的Base64与BouncyCastleProvider的jar包可在本文末尾下载源码，从源码获取jar包。 DES DES算法全称为Data Encryption Standard，即数据加密算法，它是IBM公司于1975年研究成功并公开发表的。DES算法的.....

加密算法比较3DES AES RSA ECC MD5 SHA1等

加密算法通常分为对称性加密算法和非对称性加密算法，对于对称性加密算法，信息接收双方都需事先知道密匙和加解密算法且其密匙是相同的，之后便是对数据进行加解密了。非对称算法与之不同，发送双方A,B事先均生成一堆密匙，然后A将自己的公有密匙发送给B，B将自己的公有密匙发送给A，如果A要给B发送消息，则先需要用B的公有密匙进行消息加密，然后发送给B端，此时B端再用自己的私有密匙进行消息解密，B向A发....
