SMEGMA is an engine for generating garbled shellcode using several encryption mechanisms and making it self-decryptable by putting an Intel x86 machine-code decryptor in front of it. It uses a hand-written C lexer to grab the shellcode from sourcefiles and try and identify it. Use SMEGMA to modify shellcode in which characters get ruined by regular expressions (often seen in CGI binaries, web applications and webservers).
