This is a simple yet powerful tool designed to encrypt and decrypt text using the AES-256-CBC encryption algorithm. It provides a user-friendly interface for securely transforming plain text into encrypted form and vice versa. Below is a detailed detoolion of its functionality, features, and usage.
Key Features
- —
AES-256-CBC Encryption Algorithm:
- —The tool uses the Advanced Encryption Standard (AES) with a 256-bit key in Cipher Block Chaining (CBC) mode. This ensures a high level of security for sensitive data.
- —A unique Initialization Vector (IV) is generated from the encryption key to enhance security during the encryption process.
- —
Secure Key Management:
- —The encryption key is hardcoded in the tool for simplicity. However, it is recommended to use a more complex and unique key for production environments.
- —The key is hashed using MD5 to ensure compatibility with the encryption algorithm.
- —
User-Friendly Interface:
- —The tool integrates seamlessly into a website, providing a clean and intuitive interface for users to input text and choose between encryption or decryption.
- —The interface includes:
- —A textarea for entering or pasting text.
- —Radio buttons to select the desired operation (encrypt or decrypt).
- —A "Go" button to execute the selected action.
- —
Base64 Encoding:
- —Encrypted text is encoded in Base64 format to ensure safe transmission and storage. This prevents issues with special characters and ensures compatibility across different systems.
How It Works
- —
Encryption Process:
- —When the user selects the "Encrypt" option and submits the form, the tool:
- —Takes the input text from the textarea.
- —Generates an Initialization Vector (IV) based on the encryption key.
- —Encrypts the text using the AES-256-CBC algorithm.
- —Encodes the encrypted result in Base64 format for safe display.
- —
Decryption Process:
- —When the user selects the "Decrypt" option and submits the form, the tool:
- —Decodes the Base64-encoded input text.
- —Decrypts the text using the same AES-256-CBC algorithm and the original encryption key.
- —Displays the decrypted plain text in the result area.
