c语言实现dES加密算法 c语言实现加密解密 在密码学中,微型加密算法(Tiny Encryption Algorithm,TEA)是一种易于描述和执行的块密码,通常只需要很少的代码就可实现。其设计者是剑桥大学计算机实验室的大卫·惠勒与罗杰·尼达姆。这项技术最初于1994年提交给鲁汶的快速软件加密的研讨会上,并在该研讨会上演讲中首次发表。
The code has been written to provide readability and easy understanding of the algorithm. Padding scheme used in this implementation is [PKCS5] Compilation & Installation This implementation has only been tested on Unix platform. But you may be able to compile/ run it on Windows. Make sure ...
Figure C.1 illustrates the overall structure of the simplified DES, which we will refer to as SDES. The S-DES encryption algorithm takes an 8-bit block of plaintext (example: 10111101) and a 10-bit key as input, and produces an 8-bit block of ciphertext as output. The S-DES decryp...
