![]() ![]() Gpg: assuming signed data in 'sample.txt' If the default names have been used you can leave off the name of the unencrypted file. To verify the signature, specify the signature file and then the original file. The original plain text file and the separate signature file must both be made available to the recipient. ![]() IF0EABECAB0WIQQVrPeUo9lk0dnOTCbvwxHCv6EJdAUCXtO/yAAKCRDvwxHCv6EJĭC2BAJ49fIcOdBUdE0PELySEMlKNzVnZLgCdG1gsTim3gab2dgL6qagHArSlgq8= If you do not want to share, post, or email a data file, you can sign the file with the -armor option, and it will create an ASCII text file with the signature. It is not private since anyone with the public key can decrypt the file. This both forces the recipient to verify the origin and removes any clear text content from transit. The public key is required to view the contents of the file. With the -sign option, the file is effectively encrypted with the private key. b, -detach-sign make a detached signatureĪs each option is discussed, I will sign a simple text file. With GnuPG, there are multiple methods of signing a file. In this article, I will demonstrate how to sign files before sharing via email or publishing on a web site. I have also shared how to create a key pair and export a public key so that we could receive encrypted messages. In a previous article, I introduced GnuPG by verifying a signed file and encrypting a file for a recipient by using a public key. ![]()
