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.

md5算法是计算机密码学里经典的算法，实用价值很高，设计的关键在于随机数的产生，本程序采用传统的利用计算机时钟采集种子的办法生成随机数种子。-md5 password algorithm is computer science Lane classic algorithms, highly practical, design is the key to the selection of random numbers, the procedure using the traditional use of computer clock seed collection methods generate random number seed.

While there are many AES cores around, this one is designed with LUT6 based FPGA architecture in mind from day one.  The AES Decryption Core for FPGA implements the decryption portion of the AES (a.k.a. Rijndael) algorithm described in the FIPS-197 specification. Key lengths of 128 / 192 / 256 bits are supported, each with a separate instantiation wrapper. Since the core is designed to take advantage of LUT6 based FPGA archit
