Questions fréquentes

Quick answers.

Is my private key safe?

Yes. Key processing happens entirely in your browser's memory and is never uploaded to a server or stored in local storage.

What is the difference between encrypting and signing?

Encrypting scrambles a message so only the recipient can read it, while signing provides digital proof that the message originated from you and has not been altered.

Can I decrypt a message without the private key?

No. PGP is designed so that only the holder of the specific private key and its associated passphrase can reverse the encryption process.

Which PGP standards are supported?

This tool follows the OpenPGP standard (RFC 4880), making it compatible with GnuPG, ProtonMail, and other compliant software.
