Pcryt

Pcryt is a Python-based encryption program.

About Pcryt

At the moment, Pcryt is highly simplified and minimalistic.

Running Pcryt

For v0.1.2

1. Command Line Method

Single Message Encryption/Decryption

Use the following command in the command line interface. Replace the "MESSAGE" with the text you want to encrypt, replace "SEED" with a binary value, e.g. 110010, and the "TAPPOSITION" can be a number less than the maximum number of digits in the SEED you enter.

python lfsr.py MESSAGE SEED TAPPOSITION

Use the following command to initiate "mass decrypting" mode.

python lfsr.py _attemptall_ SEED

Text File Encryption/Decryption

Use the following command in the command line interface.

python lfsr_auto.py SEED TAPPOSITION

2. Instruction Method

Single Message Encryption/Decryption

Launch the "pcryt_launcher.bat" file. Instructions are presented step-by-step.

Text File Encryption

Launch the "pcryt_encrypt.bat" file. Nothing else to do. It uses a default seed and tapposition automatically. . . .

For earlier versions

Use the following command in the command line interface. Replace the "MESSAGE" with the text you want to encrypt, and the TAPPOSITION can be a number between 0-5

python lfsr.py MESSAGE TAPPOSITION

Use the following command to initiate "mass decrypting" mode.

python lfsr.py attemptall 5
