AES-256-GCM in-browser: authenticated, PBKDF2-keyed, zero upload.
🔐 AES-256-GCM with PBKDF2-SHA256 (150k iterations) and a random 16-byte salt per encryption — output is self-contained (salt:iv:ciphertext), decryptable here or in any WebCrypto-compatible runtime. GCM authentication means wrong passwords fail loudly instead of yielding garbage.
Confidentiality plus authenticity: the GCM tag proves the ciphertext was not modified, so wrong passwords and tampered payloads fail with a clear error instead of decrypting to garbage.
Passwords are not keys — PBKDF2-SHA256 with 150,000 iterations and a per-message random salt stretches your passphrase into a 256-bit key, making offline brute-force dramatically more expensive.
Output is AES-v1:salt:iv:ciphertext in base64 — self-contained and decryptable here, in Node, or any WebCrypto runtime. No hidden state, no server round-trip.
This encrypts text in your browser; it does not manage keys, rotate them, or protect a compromised endpoint. For files and backups, age or GPG remain the right tools.
The AES Encrypt & Decrypt handles aes encryption onlinedirectly in your browser. Paste or type your input, and the tool processes it instantly — no upload, no signup, no waiting. It's built for the moments when you need a quick transformation and don't want to leave your workflow.
Because the tool runs client-side, it's fast and private. Your text never touches a server, which makes it safe for sensitive content. The interface is keyboard-friendly and works on any device with a modern browser.
Common uses: people reach for this tool when they need to use a encrypt text with password aes online, aes gcm decrypt base64, client side encryption tool no upload, or 256 bit encryption online free.
Browser-based tools like this one have a few real advantages over installed software or manual methods:
