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!)
- XOR
- AES (128-bit CBC)
Shellcrypt currently supports the following output formats (more to come in the future!)
- C
- C#
- Nim
- Raw
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

~ @0xLegacyy (Jordan Jay)
usage: shellcrypt [-h] [-i INPUT] [-e ENCRYPT] [-k KEY] [-n NONCE] [-f FORMAT] [--formats] [--ciphers] [-o OUTPUT]
[-v]
optional arguments:
-h, --help show this help message and exit
-i INPUT, --input INPUT
Path to file to be encrypted.
-e ENCRYPT, --encrypt ENCRYPT
Encryption method to use, default 'xor'.
-k KEY, --key KEY Encryption key in hex format, default (random 16 bytes).
-n NONCE, --nonce NONCE
Encryption nonce in hex format, default (random 16 bytes).
-f FORMAT, --format FORMAT
Output format, specify --formats for a list of formats.
--formats Show a list of valid formats
--ciphers Show a list of valid ciphers
-o OUTPUT, --output OUTPUT
Path to output file
-v, --version Shows the version and exits
- More output formats (python/go/rust/etc.)
- More encryption methods
- Compression methods
- Create a config system that allows for chaining encryption/encoding/compression methods
- Flag to add a decrypt method to the generated code
- Shikata encoder mayhaps?
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 :)
