Question 1

What encryption algorithm does this tool use?

Accepted Answer

The tool uses AES-256-GCM (Advanced Encryption Standard with a 256-bit key in Galois/Counter Mode), implemented via the browser's Web Crypto API. AES-256 is the same standard used by governments and financial institutions worldwide. GCM mode provides both encryption and authentication (integrity checking).

Question 2

Is the encrypted text safe to share publicly?

Accepted Answer

Yes, the encrypted ciphertext is safe to share publicly or over insecure channels. Without the correct password, the ciphertext reveals nothing about the original message. However, the security depends entirely on keeping your password secret and choosing a strong password.

Question 3

What happens if I forget my encryption password?

Accepted Answer

There is no recovery option. AES-256 encryption is designed so that without the correct password it is computationally infeasible to decrypt the message — even for us. Always store your encryption password in a safe place, such as a password manager.

Question 4

How is the password turned into an encryption key?

Accepted Answer

The tool uses PBKDF2 (Password-Based Key Derivation Function 2) to derive a 256-bit AES key from your password. PBKDF2 applies many rounds of a hash function (HMAC-SHA-256) with a random salt to make brute-force attacks computationally expensive. A new random salt is generated for each encryption operation.

Question 5

Is this tool suitable for encrypting highly sensitive data?

Accepted Answer

The tool uses strong, standard cryptography and is appropriate for personal use cases like protecting private notes or messages. For highly sensitive data (medical records, legal documents, classified information), consult a security professional and consider dedicated end-to-end encrypted communication tools.
