EncryptoCLI - By Arpan Pandey

📚 Description

Encrypto CLI is a command-line program that provides you with an intuitive and easy-to-use program that allows for a highly efficient and customizable interface to generate hashes of files or encrypt them. This allows you to encrypt and decrypt files or text data using either Fernet (AES) or PGP encryption. This is powered by the Cryptography Module and python-gnupg.

Technologies Used

• Python3
• Cryptography Module (Fernet & PGP Encryption)
• python-gnupg (GPG/PGP Support)
• Hashing Module
• Termcolor
• InquirerPy
• Scrypt

✨ Features

Encryption Methods

• AES (Fernet): Symmetric encryption using passwords
• PGP: Asymmetric encryption using public/private keys

Operations

• Hashing: Generate cryptographic hashes (MD5, SHA256, SHA512, BLAKE2)
• Encryption: Protect your data with multiple cipher methods
• Decryption: Recover encrypted data
• Steganography: Hide encrypted data in images

How it works?

The idea is very simple. The program first asks you about which operation do you want to perform and then asks you 2-3 questions relative to which operation you have selected.

Hashing

You can generate hashes for text or file data by selecting the algorithm from the 5 options provided: The five algorithms supported are:

• MD5
• SHA256
• SHA512
• BLAKE2
• BLAKE2b

Also, if you are interested in an analysis of these algorithms or implementing them by yourself you can head over to this article that I wrote on hashing.

Encrypting

You can encrypt data by going through these steps.

1. Select the type of data you want to encrypt.
2. Select the encryption method (AES or PGP)
3. Input the data (either the text or path to a file).
4. For AES: Enter a password. For PGP: Enter recipient's email.
5. And you are done.

Decrypting

You can decrypt data by going through these steps.

1. Select the type of data you want to decrypt.
2. Select the decryption method (AES or PGP)
3. Input the data (either the text or path to a file).
4. Enter the password or passphrase.
5. And you are done.

Steganography

You can encrypt and hide your data in an image using LSB (Least Significant Bit) or DCT (Frequency Domain) steganography methods. Both methods support PNG format for lossless embedding.

Encrypt

1. Select the type of data you want to encrypt.
2. Select Image as output type
3. Input path to the image where your secret will be hidden
4. Enter the text/secret you want to encrypt and hide
5. Enter a password.
6. And you are done your secret has been hidden in the image named "encrypto.png"

Decrypt

1. Select Image as the type of data you want to decrypt.
2. Input path to the image file you want to decrypt.
3. Enter the text/secret you want to encrypt and hide
4. Enter the password.
5. And you are done.

🐋 Docker

You can pull this image from Docker Hub and build it very easily.

1. Just pull the image.

   docker pull arpanpandey/encrypto:latest
   

OR

1. You can build the image using.

   docker build --pull --rm -f "Dockerfile" -t arpanpandey/encrypto:latest "."
   

2. Running the container with the image (Be sure to put the -t and -d flag.)

   docker run -t -d arpanpandey/encrypto:latest
