A GPG key, or GNU Privacy Guard key, is a cryptographic key used for encrypting and signing data. GPG is an implementation of the OpenPGP standard, which allows users to secure their communications and verify the authenticity of messages or files.
There are two main types of GPG keys:
Public Key: This key can be shared with anyone and is used to encrypt messages that only the corresponding private key can decrypt. It can also be used to verify signatures made with the associated private key.
Private Key: This key is kept secret and is used to decrypt messages that were encrypted with the corresponding public key. It is also used to create digital signatures.
GPG keys are commonly used for secure email communication, file encryption, and software distribution to ensure that the software has not been tampered with.
