Creates an instance of a cryptographic object to perform the specified implementation of the data encryption standard 创建加密对象的实例以执行数据加密标准(
Des , the data encryption standard , is probably the most commonly used symmetric key cipher in the world Des ,即数据加密标准,可能是世界上最常用的对称密钥加密算法。
Encryption algorithm that can be used as a replacement for data encryption standard or international data encryption algorithm 用于替代数据加密标准或国际数据加密算法的加密方法。
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 is based on the data encryption standard algorithm with variations intended to discourage use of hardware implementations of a key search 它基于数据加密标准( data encryption standard )算法,并具有一些用来禁用密钥搜索的硬件实现的变种。
If text is encrypted with a weak key , encrypting the resulting cipher again with the same weak key returns the original text . there are four known weak keys for the data encryption standard 如果文本是用弱密钥加密的,则使用同一弱密钥再次加密所得到的密码将会返回原始文本。
If text is encrypted with a semi - weak key , encrypting the resulting cipher with the partner of that semi - weak key returns the original text . there are six known semi - weak key pairs for the data encryption standard 如果文本是用半弱密钥加密的,则用该半弱密钥的另一方加密产生的密码将会返回原始文本。
Data encryption and information authentication are separated conventionally , such as the data encryption standard of america which encrypts the data only and the digital signature standard which authenticates the information only 如美国的数据加密标准( des )只对数据的安全性进行保护,数据签名标准( dss )只对信息发送与接收进行确认。
