Text Encrypt / Decrypt
Encrypt and decrypt text using AES-256-GCM. All processing happens entirely in your browser — no data is ever sent to a server.
Your password never leaves this page. Use a strong, unique password.
How it works: Encryption uses AES-256-GCM via the browser's native SubtleCrypto API. Your password is derived using PBKDF2 (310,000 iterations, SHA-256). The encrypted output is a Base64-encoded string containing a random salt, IV, and ciphertext — all required for decryption.
