I use a block cipher algorithm for encryption that requires the clear data bytes to be in blocks of 8 bytes, so I pad the last incomplete block with some characters.

我对需要将明文数据字节放在8字节块的加密使用块密码算法，所以我用一些字符填充最后一个不完整的块。

All the information necessary for decryption is present within the XML encryption tags: the name of the encryption algorithm, the type of data that was encrypted, and the name of the encryption key.

XML加密标记中存在着解密需要的所有信息：加密算法的名称、加密的数据类型以及加密密钥的名称。

DES, the United States Data Encryption Standard, is a block cipher algorithm with 8-byte long blocks and a key length of 56 bits.

即美国国家数据加密标准(the United States Data Encryption Standard)，是一个块密码算法，块长8字节，密钥长56位。

Well, that really does not make much of a difference when you expose the entire database table and have way too much faith in the 34 year old encryption algorithm reported to be used to safeguard the data.
