Encryption / Decryption Tool
Encrypt and decrypt text locally using AES-GCM and a passphrase.
What Browser-Based Encryption Is For
Browser-side encryption helps protect short text locally before you store or transmit it elsewhere. It is useful for lightweight workflows, notes, or internal handoffs where you want quick encryption without a separate app.
Why Passphrases Matter
Encryption strength depends heavily on the quality of the passphrase. A weak or reused passphrase undermines the value of the encrypted output.
Best Use Cases
Use local encryption for temporary sensitive notes, lightweight sharing, or demonstrations. For production-grade secrets management, dedicated security tooling is still the better option.
