Data encryption standard ( des ) is a federal standard adopted by the u . s . government for the 数据加密标准数据加密标准是美国政府就商业及政府数据
A private key encryption - decryption algorithm that uses a key that is twice the length of a data encryption standard ( des ) key 一种密钥加密-解密算法,其使用一种两倍于数据加密标准( des )密钥长度的密钥。
It uses symmetric and cryptographic algorithms like data encryption standard ( des ) , and triples des to encrypt the payload . together , the ipsec esp and ah protocols provide privacy , integrity , and authentication of ip packets Esp利用对称加密算法(如des ,三重des )加密有效载荷。 ah与esp一起为ip包提供机密性,完整性和身份源认证服务。
