PGP ENCRYPTION

Concept: Public vs Private Key

PGP (Pretty Good Privacy) uses asymmetric cryptography. Imagine a mailbox.

  • Public Key: The slot on the mailbox. Anyone can put a letter in (encrypt a message for you), but they cannot take it out. You give this key to everyone.
  • Private Key: The key that opens the mailbox. Only you have it. You use it to read your messages. NEVER SHARE THIS.

How to Encrypt an Address

When sending your shipping address to a vendor:

  1. Import the Vendor's Public Key into Kleopatra.
  2. Type your address in the Notepad.
  3. Click "Recipients" tab -> Check the Vendor's name.
  4. Click "Encrypt".
  5. Copy the text block (-----BEGIN PGP MESSAGE-----) and paste it into the order form.

Technical Details (RSA vs ECC)

Nexus supports both RSA (4096-bit recommended) and ECC (Curve25519) keys. While ECC keys are shorter and faster, RSA keys have broader compatibility with older PGP implementations. We recommend RSA 4096 for maximum compatibility.
