Text Encryptor / Decryptor

This tool lets you securely encrypt and decrypt text in your browser using AES-256-GCM, one of the most secure symmetric encryption algorithms available. Your data never leaves your device. Encryption uses PBKDF2 key derivation (100,000 iterations, SHA-256) to turn your password into a strong cryptographic key. A random 16-byte salt and 12-byte IV are generated for each encryption, ensuring that the same plaintext encrypted twice produces different ciphertext. The output is Base64-encoded, making it easy to store or transmit as plain text. To decrypt, simply paste the ciphertext and enter the same password. This tool is ideal for protecting sensitive notes, credentials, or personal data.
