PGP (Pretty Good Privacy) is a public key encryption program that has become the most popular standard for email encryption. (The "pretty good" bit is meant to be a bit of an ironic understatement.) In addition to encrypting and decrypting email, PGP is used to sign messages so that the receiver can verify both the identity of the sender and the integrity of the content. PGP uses a private key that must be kept secret and a public key that sender and receiver must share. The technology is also known as GPG (Gnu Privacy Guard or GnuPG), which is a fully compatible GPL-licensed alternative.
Setting up PGP/GPG will allow you to:
- Verify automated messages from Kraken, so that you can be sure they came from us and haven't been tampered with en route.
- Receive encrypted automated email from us. Some of these emails will contain sensitive information, such as account recovery instructions, so encryption adds an extra layer of security.
- Help secure your Kraken account if your email is ever compromised.
