Encryption Method

Safe Text Send employs the robust AES-256-CBC (Advanced Encryption Standard with 256-bit key in Cipher Block Chaining mode) to ensure top-tier security. Here's how it works:

• Key Generation: The user-provided secret key is hashed using the MD5 algorithm to create a 256-bit key suitable for AES encryption.
• Initialization Vector (IV): An IV is derived from the double-hashed key to enhance security by ensuring that identical plaintexts produce different ciphertexts.
• Encryption Process: The input text is encrypted using AES-256-CBC, converting it into a Base64-encoded ciphertext that is unreadable without the key.
• Decryption Process: The encrypted text is decoded from Base64 and decrypted using the same key and IV, restoring the original text.
• Security Features: The use of a unique IV and a strong encryption algorithm ensures that your data is protected against unauthorized access.

By leveraging the Web Crypto API, Safe Text Send performs all encryption and decryption operations directly in the browser, ensuring that your data never leaves your device. This client-side approach maximizes privacy and security.
