DES uses "keys" where are alsoapparently16 hexadecimal numbers long, orapparently64 bits long. However, every 8th key bit is ignored in the DES algorithm, so that the effective key size is 56 bits. But, in any case, 64 bits (16 hexadecimal digits) is...

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。 DES使用简介# 使用DES需要设置加密内容、加密key、加密混淆向量iv、分组密码模式、填充模式。
The DES Algorithm is a block cipher that uses symmetric keys to convert 64-bit plaintext blocks into 48-bit ciphertext blocks. The (DES) Data Encryption Standard Algorithm was developed by the IBM team in the 1970s. It has since been accepted by the National Institute of Standards and ...
Creates an uninitialized DES instance. To use the Cipher, it must be initialized with a Key and algorithm parameters, usually in the form of an AlgorithmIdentifier. Method Detail initialize public void initialize(AlgorithmIdentifieralgID,SymmetricKeykey,Padding.IDpaddingID,RandomBitsSourcerbs) throwsAlgori...
