安全哈希算法(Secure Hash Algorithm)主要适用于数字签名标准(Digital Signature Standard DSS)里面定义的数字签名算法(Digital Signature Algorithm DSA)。对于长度小于2^64位的消息,SHA1会产生一个160位的消息摘要。当接收到消息的时候,这个消息摘要可以用来验证数据的完整性。在传输的过程中,数据很可能会发生变化,那么...

The triple DES algorithm uses the DES-EDE3 method when a 24 byte key is supplied. This means there are three DES operations in the sequence encrypt-decrypt-encrypt with the three different keys. The first key will be bytes 1 to 8, the second key bytes 9 to 16 and the third key bytes...
