How does PGP encryption work?
PGP is a cryptographic method that lets people communicate privately online.
When you send a message using PGP, the message is converted into unreadable ciphertext on your device before it passes over the Internet.
Only the recipient has the key to convert the text back into the readable message on their device..
What is a key ID?
A key is a piece of data used in the encryption algorithms that protect the content. There are two parts to each key: a license key seed and a key ID (often abbreviated as KID). The key ID is public, and is stored in the file header as a way to identify the key required to decrypt the file.
How do I find my GPG key?

What are GPG keys used for?
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.
What is the need of key ID in PGP?
PGP uses key IDs to refer to public keys for a variety of purposes. These are not, properly speaking, fingerprints, since their short length prevents them from being able to securely authenticate a public key. 32bit key ids should not be used as current hardware can generate 32bit key id in just 4 seconds.
What are GPG keys in Linux?
The GNU Privacy Guard GnuPG allows you to encrypt and sign your data and communications; it features a versatile key management system, along with access modules for all kinds of public key directories. GnuPG, also known as GPG, is a command line tool with features for easy integration with other applications.
