A PGP signature is a file that allows someone to verify that a set of information (like an mp3 file from your favorite podcast) was “signed” by who claims to have signed it.<\/p>\n
Cryptographic “signing” is very similar to signing things in the physical world. Someone can look at your signature and verify that you signed it by comparing it to something you’ve signed in the past. Cryptographic signing works by creating a file that is unique to both the signer’s private key and the file they are signing, so if someone tried to impersonate the signer, they would not be able to create a valid signature for whatever they were trying to pass off.<\/p>\n
The signer’s public key is used to verify that a file and it’s signature are valid.<\/p>\n
