·签名信息举例—— Examples of signed messages
The email contains several sections that are separated by separators. We used -verify command to check the signatures.

E:\good signed>gpg --verify part3.asc

gpg: Signature made 11/21/09 15:59:46 W. Europe Standard Time using DSA key ID 6C14565D

gpg: Good signature from 'Internet Security and Privacy (Course key)'

GPG tells about the signatures that this file has. It returns an indication of either a good signature or a bad signature. A good signature means that the signature of the file matches the signature that GPG expects, from the mentioned key on this file. Another possible output is a bad signature which means that the contents of the file were altered.

E:\Bad Signed>gpg --verify part4.asc

gpg: Signature made 11/21/09 15:59:46 W. Europe Standard Time using DSA key ID 6C14565D

gpg: BAD signature from 'Internet Security and Privacy (Course key)'

We can also use the -decrypt command for this purpose. This command not only provides the information os the signatures but also provides the decrypted contents of the file. As shown in the first line below.

E:\Bad Signed>gpg --decrypt part4.asc

eb8c990b7e894bcafa73b1b3a8302b865ed0fbbf

gpg: Signature made 11/21/09 15:59:46 W. Europe Standard Time using DSA key ID 6C14565D

gpg: BAD signature from 'Internet Security and Privacy (Course key)'
