Are my PGP private keys uploaded to your server?

Never. OpenPGP.js runs entirely client-side inside your browser thread. Private keys and decrypted plaintexts exist solely in your local device RAM.

Can I decrypt PGP messages encrypted with GnuPG or ProtonMail?

Yes. This tool adheres to RFC 4880 OpenPGP standards, fully interoperable with GnuPG, Thunderbird, ProtonMail, and Keybase.

Frequently Asked Questions

Which is recommended: Curve25519 (ECC) or RSA?

Curve25519 provides equivalent ~128-bit security to RSA 3072 while generating significantly smaller key signatures with near-instantaneous key generation in the browser.

Can encrypted messages be cracked by QuickCoderHub?

No. OpenPGP asymmetric cryptography ensures only the holder of the matching private key can ever decrypt ciphertext.
