About Encrypt & Decrypt.

Encrypt Text With AES-256 — Locally in Your Browser

Paste or type any text, enter a password, and CipherForces encrypts it using AES-256-GCM via the browser's native Web Crypto API. The recipient decrypts with the same password. All encryption and decryption happen locally.

Common Use Cases

Secure sharing: Encrypt sensitive text before pasting it into email, chat, or a shared document.
Password-protected notes: Encrypt personal notes that you need to share with yourself across devices.
Credential handoff: Encrypt passwords, API keys, and license codes before sending them to a teammate.
Legal hold: Encrypt sensitive correspondence to preserve attorney-client privilege in transit.

Key Features

AES-256-GCM: The gold-standard modern symmetric cipher.
PBKDF2 key derivation: 310,000 iterations with per-message salt — prevents brute-forcing the password.
Handles real documents: Encrypt anything you can paste — notes, configs, entire documents' text — up to about 5 MB.
Self-contained output: Encrypted payload includes salt, IV, and ciphertext in a portable format.
Backwards compatible: Decryption works on any CipherForces-encrypted output forever.

Privacy: Encryption uses crypto.subtle. Your password and plaintext never leave your browser.

FAQ

Frequently asked questions.

Is my text uploaded to a server when I encrypt it?

No. This encryption tool runs entirely in your browser using JavaScript, so your text and password never leave your device or reach any server. The encryption happens locally on your computer. There is no signup, and the tool is free to use with nothing transmitted over the internet.

How do I encrypt text with AES-256?

Paste or type your text into the tool, enter a password, and click encrypt. The tool uses AES-256 to scramble your content right in the browser. Copy the encrypted output to save or share it. To read it later, paste it back, enter the same password, and decrypt.

Can I decrypt my text if I forget the password?

No. AES-256 encryption depends on your password, and there is no recovery option or backdoor. Without the exact password used to encrypt, the data cannot be decrypted. Store your password somewhere safe, because losing it means the encrypted text stays permanently locked.

What does the Encrypt and Decrypt tool actually do?

It encrypts your text with AES-256, a widely used encryption standard, then decrypts it back when you enter the correct password. Everything runs client-side in your browser, so your data stays private. Use it to protect notes, credentials, or any sensitive text before storing or sharing it.
