Signsrch is a tool that searches for signatures inside raw files and executables. It can recognize a large number of compression, multimedia, and encryption algorithms and many other things like known strings and portions of anti-debugging code. Definitions can be manually added, since they are based on an ease-to-modify text signature file that is read at runtime. It also supports the scanning of processes, conversion of executable memory offsets, 8, 16, 32 and 64 bits, float and double, plus automatic CRC table creation and C style strings.
