What Is PGP / GPG Key
GPG, or GNU Privacy Guard, is a public key cryptography implementation. This allows for the secure transmission of information between parties and can be used to verify that the origin of a message is genuine.
A problem that many users face is how to communicate securely and validate the identity of the party they are talking to. Many schemes that attempt to answer this question require, at least at some point, the transfer of a password or other identifying credentials, over an insecure medium.
To get around this issue, GPG relies on a security concept known as public key encryption. The idea is that you can split the encrypting and decrypting stages of the transmission into two separate pieces. That way, you can freely distribute the encrypting portion, as long as you secure the decrypting portion.
This would allow for a one-way message transfer that can be created and encrypted by anyone, but only be decrypted by the designated user (the one with the private decrypting key).
PGP / GPG Key Support In GCPS
In GCPS, we make sure you that the E-mails you are receiving is from us by encrypting the message using your PGP Public key. Only you can decrypt the message with your PGP Private key.
How do I get started?
1. Go to Account settings and enter your PGP/GPG Public Key in Login & Security form and update.
How does it work?
1. Decrypt the message in the E-mails you received using your Private key.
2. After Decryption, you will get the human readable message.
