VHDL implementation of the twofish cipher for 128,192 and 256 bit keys. The implementation is in library-like form All needed components up to, including the round/key schedule circuits are implemented, giving the flexibility to be combined in different architectures (iterative, rolled out/pipelined etc). Manual in English is included with more details about how to use the components and/or how to optimize some of them. All testbenches are provided (tables, variable key/text, ECB/CBC monte carlo) for 128, 192 and 256 bit key sizes, along with their respective vector files.-VHDL implementation of the twofish cipher for 128,192 and 256 bit keys.

A simple cpp program, that receives a file, does a bit-wise "not" for every character, and adds "not" to the extension. Repeated running does the same and removes the "not" from extension. This a "pseudo-encryption", but very useful to avoid automated filtering software. This way it is possible to send "exe" files (or anything else) without the emails being blocked... First - send the source code, have your (enlightened) recipient compile it, then send the "notted" file. The code is not very efficient though, I only had 30 minutes to invest... :)-A simple cpp program, that receives a file, does a bit-wise "not" for every character, and adds "not" to the extension.
