Frequently Asked Questions
What encryption algorithm is used?▾
AES-GCM (Advanced Encryption Standard in Galois/Counter Mode) with 256-bit keys. Keys are derived from your password using PBKDF2 with 100,000 iterations and SHA-256.
Is my data safe? Does it leave my browser?▾
Yes, your data is safe. All encryption and decryption happens entirely in your browser using the Web Crypto API. No data is ever sent to any server.
What is the output format?▾
The ciphertext is Base64-encoded and includes the salt (16 bytes) and IV (12 bytes) prepended to the encrypted data. This means you only need the password to decrypt.
Can I decrypt data encrypted with other tools?▾
Only if the other tool used the same format: PBKDF2 key derivation (100k iterations, SHA-256), AES-256-GCM, with salt and IV prepended in the same order.
