Cryption101

Cryption101 is a versatile Python script that combines multiple functionalities:

1. Caesar Cipher for text encryption and decryption.
2. Password Strength Checker to evaluate the strength of your passwords.
3. XOR Image Encryption/Decryption to securely encrypt and decrypt image files.
4. File Encryption/Decryption using symmetric key encryption.

Features

Caesar Cipher

Encrypt or decrypt text using the classic Caesar Cipher technique.

Usage

python3 cryption101.py caesar -e "Hello World" -s 3

Arguments

-e, --encrypt: Text to encrypt.
-d, --decrypt: Text to decrypt.
-s, --shift: Shift value (1 to 26).

Password Strength Checker

Check the strength of a password and get recommendations to make it stronger.

Usage

python3 cryption101.py password -p "YourPassword123!"

Arguments

-p, --password: Password to check strength.

XOR Image Encryption/Decryption

Encrypt or decrypt an image using XOR encryption.

Usage

python3 cryption101.py xor -i path/to/input_image.jpg -o path/to/output_image.jpg -k 123

Arguments

-i, --input: Path to the input image file.
-o, --output: Path to save the output image file.
-k, --key: Key for XOR encryption/decryption (0 to 255).

File Encryption/Decryption

Encrypt or decrypt all files in the current directory using symmetric key encryption. File Encryption

Encrypt all files in the current directory except the script and key files.

Usage

python3 cryption101.py file-encrypt

File Decryption

Decrypt all files in the current directory using a provided key.

Usage

python3 cryption101.py file-decrypt -k "randsome"

Arguments

-k, --key: Key for decryption.

Installation

Clone the repository:

git clone https://github.com/MohakGupta2004/cryption101.git

Navigate to the project directory:

cd cryption101

Run the script with the desired functionality:

python3 cryption101.py -h

Examples

Caesar Cipher

Encrypt the text "Hello World" with a shift of 3:

python3 cryption101.py caesar -e "Hello World" -s 3

Decrypt the text "Khoor Zruog" with a shift of 3:

python3 cryption101.py caesar -d "Khoor Zruog" -s 3

Password Strength Checker

Check the strength of the password "YourPassword123!":

python3 cryption101.py password -p "YourPassword123!"

XOR Image Encryption/Decryption

Encrypt an image with key 123:

python3 cryption101.py xor -i path/to/input_image.jpg -o path/to/output_image.jpg -k 123

Decrypt the image with key 123:

python3 cryption101.py xor -i path/to/output_image.jpg -o path/to/decrypted_image.jpg -k 123

File Encryption

Encrypt all files in the current directory:

python3 cryption101.py file-encrypt

File Decryption

Decrypt all files in the current directory with the key "randsome":

python3 cryption101.py file-decrypt -k "randsome"
