iilegacyyii/shellcryptA QoL tool to obfuscate shellcode. In the future will be able to chain encoding/encryption/compression methods.
A single-file cross-platform quality of life tool to obfuscate a given shellcode file and output in a useful format for pasting directly into your source code.
These are going here because they deserve it
Shellcrypt currently supports the following encryption methods (more to come in the future!)
Shellcrypt currently supports the following output formats (more to come in the future!)
Encrypt shellcode with a random key
python ./shellcrypt.py -i ./shellcode.bin -f c
Encrypt shellcode with 128-bit AES CBC
python ./shellcrypt.py -i ./shellcode.bin -e aes -f c
Encrypt shellcode with a user-specified key
python ./shellcrypt.py -i ./shellcode.bin -f c -k 6d616c77617265
Output in nim format
python ./shellcrypt.py -i ./shellcode.bin -f nim
Output to file
python ./shellcrypt.py -i ./shellcode.bin -f nim -o ./shellcode_out.nim
Get a list of encryption methods
python ./shellcrypt.py --ciphers
Get a list of output formats
python ./shellcrypt.py --formats

pssst this is still heavily in development so if you'd like to contribute, have a go at working on one of the many TODO's in the code :)
