bitsliced-aes | A bitsliced implementation of ECB and CTR AES

bitsliced-aes is a C library. bitsliced-aes has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

Bitslicing is a technique to compute steps in an algorithm 1 bit at a time. Each bit in a processor word would be a part of a different data stream for that particular algorithm. It is attractive because then it can run many different streams in parallel (depending on the word length). E.g. a 32 bit word length can compute 32 different streams in parallel. Some encryption algorithms allow blocks to be operated on in parallel like AES CTR. So if there is enough input, say 32 blocks, then a 32 bit processor can achieve full utilitization by filling all bits in word and enciphering all blocks in parallel.
