This is a rudimentary implementation of a One-time pad CLI tool built in rust.
The tool has 3 operations.
- GenerateKey which is used to generate a key of a specified length. It will save the key as key.txt in the location where the tool is run.
- Encode which is used to encode a message with an existing key. It will save the encoded message as encoded.txt in the location where the tool is run.
- Decode which is used to decode a message with an existing key. It will save the decoded message as decoded.txt in the location where the tool is run.
- Download the cli tool for your OS
- Invoke the CLI using
otp <command> <option>- For example if I want to send messages that will be 11 characters long e.g
hello worldI would generate a 11 character key usingotp GenerateKey -l 11 - If I then wanted to encode my message saved as message.txt with my key I just generated saved as key.txt I would use
otp Encode -k key.txt -m message.txt - If I then wanted to decode a message I received saved as encoded.txt using the key saved as key.txt I would use
otp Decode -k key.txt -m encoded.txt
- For example if I want to send messages that will be 11 characters long e.g
