Fortify
Fortify is a command-line tool designed to enhance file security through encryption.
Features
- Fortifies any file through encryption, then decrypts or executes the fortified file.
- Encrypts file using AES-256.
- Protects the AES secret key with either Shamir's Secret Sharing (SSS) or RSA encryption.
Usage Overview
Installing fortify
fortify is distributed as a standalone static executable binary, requiring no external dependencies.
1. Linux
/usr/bin/env sh -c "$(curl -fsSL https://i3ash.com/fortify/install.sh)"
2. macOS
brew install i3ash/bin/fortify
3. go install
go install github.com/i3ash/fortify@latest
4. Docker
docker run --rm i3ash/fortify version
5. Download
Download a precompiled binary from here.
Run fortify with SSS (Shamir's Secret Sharing)
Encryption
Encrypt files with randomly generated key parts:
fortify encrypt -i <input_file> -o <output_file>
Encrypt files with specified key parts:
fortify sss random -b 32 -p <number_of_shares> -t <threshold>
fortify encrypt -i <input_file> <key_part1> <key_part2> ...
Decryption
Decrypt files with specified key parts:
fortify decrypt -i <fortified_file> <key_part1> <key_part2> ...
Execution
Execute fortified files with specified key parts:
fortify execute -i <fortified_file> <key_part1> <key_part2> ...
Run fortify with RSA
Encryption
Encrypt files with RSA public key:
fortify encrypt -i <input_file> -k rsa <public_key_file>
Decryption
Decrypt files with RSA private key:
fortify decrypt -i <fortified_file> <private_key_file>
Execution
Execute fortified files with RSA private key:
fortify execute -i <fortified_file> <private_key_file>
