It describes a Data Encryption Algorithm (DEA), which is defined in the ANSI standard X9.32. The algorithm divides a message into 64-bit blocks and uses a 56-bit key. It uses a complex combination of transpositions (rearrangement of bits), substitutions (replacing one bit group with another...

二、Data Encryption Standard (DES) DES是一个运用Feistel Network来进行加密的流程,输入值的长度(block length)为64 bits, master key的长度为56 bits,一共进行16轮Feistel运算。因为是20世纪70年代提出来的加密标准,现在看来,56 bits的master key太短了,所以已经不再被推荐使用。

Data Encryption Standard (FIPS 46-3) was officially withdrawn in May 2005.Triple DES (3DES), a variant of DESthat can use up to three different keys for greater effective key length, has also beendeprecated. 3DES performs three iterations of the DES algorithm; the strongest version of 3DES ...
The Advanced Encryption Standard (AES)—this algorithm is the standard currently accepted by the U.S. Government and other organizations. It works well in 128-bit form, however, AES can use keys of 192 and 256 bits. AES is considered resistant to all attacks, except brute force. Elliptic ...
