You do not need to trust me with your safety. Properly implemented cryptography works and if you use it to keep your address from anyone but your vendor reading and then not transmit any other personally identifiable information you are quite safe as a regular buyer. If you are a vendor or large buyer, there are other ways to further protect yourself too and I would encourage you to read up on the security advice given on this forum to ensure it is reliable information. If you are cautious and take measures to protect yourself, not even I could then place you at risk.
