Quick answers to common questions
AES-256-GCM with a key derived via PBKDF2 (100,000 iterations, SHA-256) from your password.
No. Encryption and decryption run entirely in your browser using the Web Crypto API.
Base64 encoding of salt + IV + encrypted bytes. Keep the full string to decrypt later.
Yes. Without the correct password, decryption is not possible. Store passwords safely.
It is convenient for casual protection. For critical secrets, use audited tools and key management.
Switch to Decrypt, paste the Base64 ciphertext, enter the same password, and click Decrypt.
Yes, after the page loads — no server calls during encrypt/decrypt.
Yes.
