DES全称为Data Encryption Standard,即数据加密标准,是一种使用密钥加密的块算法,1977年被美国联邦政府的国家标准局确定为联邦资料处理标准(FIPS),并授权在非密级政府通信中使用,随后该算法在国际上广泛流传开来。需要注意的是,在某些文献中,作为算法的DES称为数据加密算法(Data Encryption Algorithm,DEA),已与作为标准...

23. DES_quad_cksum:is a Kerberos v4 function. It returns a4 byte checksum from the input bytes. The algorithm can be iterated over the input, depending onI<out_count>, 1, 2, 3 or 4 times. If I is non-NULL, the 8 bytes generated by each pass arewritten into I. 24. DES_fcrypt...

MD5算法广泛应用于数字签名、数据完整性校验、密码学等领域。 MD5(Message-Digest Algorithm 5)是一种常用的哈希算法,它将任意长度的消息压缩成一个128位的消息摘要(即哈希值),并且具有不可逆性、唯一性、抗碰撞性等特点。 二、MD5加密解密的原理? MD5算法的原理是将输入的...
