Crypto CLI

A Rust CLI tool to generate RSA key pair, encrypt and decrypt message.

Features

• Generate private and public RSA key pairs.
• Encrypt message using public key with the option of hex encoding.
• Decrypt message using private key with the option of hex decoding.

Getting Started

1. Run the line below to get more information on each command.

cargo run -- --help

2. Run a specific command.

cargo run -- <COMMAND>

Commands

1. You can get more specific information about any commands by using --help with a specific command. For example, you can run any of the following commands for varying level of detail:

   • cargo run -- --help
     

   • cargo run -- encrypt --help
     

   • cargo run -- decrypt --help
     

2. More information on shorthand commands like --text (shortcut -t) can be found in --help.
3. Currently available commands:

   • cargo run -- generate
     

   • cargo run -- encrypt --text <TEXT> --public_exponent <PUBLIC_EXPONENT> --modulus <MODULUS>
     

   • cargo run -- decrypt --text <TEXT> --private_exponent <PRIVATE_EXPONENT> --public_exponent <PUBLIC_EXPONENT> --modulus <MODULUS>
     

   • cargo run -- encrypt-encode --text <TEXT> --public_exponent <PUBLIC_EXPONENT> --modulus <MODULUS>
     

   • cargo run -- decrypt-decode --text <TEXT> --private_exponent <PRIVATE_EXPONENT> --public_exponent <PUBLIC_EXPONENT> --modulus <MODULUS>
     

4. Test commands for testing RSA encryption decryption cases:
