AES-GCM in your browser. Your key stays with you.
Privacy guarantee: bitmods does not see, store, or transmit your key or your text.
Everything happens in your browser using the native SubtleCrypto API (AES-GCM 256-bit).
The key lives in localStorage on your device. If you want to decrypt on another device,
copy the key out first.
Sometimes you need to store sensitive text somewhere you don't fully trust — a shared note app, a cloud clipboard, a file that lives somewhere inconvenient. This tool encrypts it with AES-GCM-256 before you paste it anywhere, and decrypts it again when you need it back.
The key is generated in your browser using crypto.getRandomValues() and stored
in localStorage. It never touches a server. No account, no login, no retention.
The ciphertext without the key is mathematically useless.
If you need to decrypt on a different device, copy the key out using the "Copy" button and store it somewhere safe — a password manager is the obvious choice. Losing the key means losing the data. That's the deal with real encryption.
This is a convenience tool for light-duty encryption, not a replacement for proper end-to-end encrypted storage. But for casual "I just don't want this sitting in plaintext" use cases, it does the job without requiring any software, accounts, or trust in third parties.
