PyCrypt

PyCrypt is a Command-Line Interface (CLI) program, for encryption and decryption using various techniques. PyCrypt takes in an input file, then encrypts/decrypts and stores the result into the output file, provided by the user.

Pycrypt commands:

• all: Returns a list of all available techniques for cryption
• category: Returns a list of techniques under a category given by the user
• encrypt: Encrypts the content of the input file, stores them in output file
• decrypt: Decrypts the content of the input file, stores them in output file

Encrypt command

The encrypt command takes 4 parameters:

• -t or --technique: Technique to be used for encryption
• -i or --input_file: The file whose contents have to be encrypted
• -o or --output_file: The file in which the encrypted data has to be saved
• k or --key: Key that is used in the encrypting technique (if any)

Example

pycrypt encrypt --technique caesercipher --input_file input.txt --output_file output.txt --key 7

Decrypt command

The decrypt command takes 4 parameters:

• -t or --technique: Technique to be used for decryption
• -i or --input_file: The file whose contents have to be decrypted
• -o or --output_file: The file in which the decrypted data has to be saved
• k or --key: Key that is used in the decrypting technique (if any)
