Importing a public key.Īs discussed earlier to encrypt a file/message so that the only the intended recipient can view its contents, we need their public key. Reason for revocation: Key has been compromisedĪfter this operation a file revoke.crt is created in the specified directory, to be safe we can change permissions so that only us can have permissions to r/w/e it. Please select the reason for the revocation:Įnter an optional description end it with an empty line: gpg -output ~/revoke.crt -gen-revoke steps, sec rsa2048/F1E1BD6A36CB85A8 bob (key generation for bob) Ĭreate a revocation certificate for this key? (y/N) y Public and secret key created and signed.Īssuming that our key has been compromised, a revocation certificate should be generated so as to disassociate the old key from our identity so we can generate a new one. Gpg: revocation certificate stored as '/home/bob/.gnupg/openpgp-revocs.d/45C0217B9CE01A924065FC4DF1E1BD6A36CB85A8.rev' Gpg: directory '/home/bob/.gnupg/openpgp-revocs.d' created Gpg: key F1E1BD6A36CB85A8 marked as ultimately trusted Gpg: /home/bob/.gnupg/trustdb.gpg: trustdb created

Generator a better chance to gain enough entropy. Some other action (type on the keyboard, move the mouse, utilize theĭisks) during the prime generation this gives the random number We need to generate a lot of random bytes. GnuPG needs to construct a user ID to identify your key.Ĭhange (N)ame, (C)omment, (E)mail or (O)kay/(Q)uit? O Please specify how long the key should be valid.

Here is the whole process, gpg (GnuPG) 2.2.27 Copyright (C) 2021 Free Software Foundation, Inc. Next we will enter a paraphrase and confirm it, after which we are done and will have our keys generated. If the details are ok we type O and proceed. The next step is entering your details such as a name, email address and a comment, then a confirmation will follow, we can opt to change any of the entered details. The next step involves selecting the time period in which this key we are about to generate will be valid, for example 1y means that after one year we will need to renew it, 0 means that it will never expire, 1 means it expires after one day.Īfter entering the duration, you will be prompted for a confirmation. Next we select a bit-length for the keys and press enter. To generate a key locally we write, gpg -full-generate-keyĪfter executing this command we will be prompted to choose an encryption algorithm, enter the number and press enter to proceed.
We can also extract the contents of the file while decrypting it as follows, gpg file.gpgĪfter this operation the original file file will be created. If you waited about 10 minutes you should be prompted for a password, otherwise gpg will print out the encrypted text from file.gpg as output without requiring a password. To decrypt a file we use the -d option, gpg -d file.gpg Once done, you should see the file file.gpg which will hold the encrypted contents of file.
Gpg mail decrypt password#
The syntax is as follows, gpg įor encrypting a file we use the -c option, gpg -c fileĪfter executing this command a prompt for entering the password and its confirmation will be displayed.
Therefore public keys must be shared between the two parties, that is the sender must have the receiver's public key and vice versa.Īlthough one can share public keys, private keys should remain private. Sending a file involves the sender securely encrypting a file with a his/her own private key together with the recipient's public key and to decrypt the sent file the receiver uses his/her private key together with the sender's public key. gpg allows one to encrypt and sign data and communications, additionally it features versatile management of keys including access modules for all kinds of public key directories. Linux provides gpg(Gnu Privacy Guard), an open source implementation of PGP(Pretty Good privacy). Password protecting a system doesn't prevent one from bypassing it and having access to files and directories therefore it is necessary to have essential files encrypted with a password such that even if the hard disk is compromised any unauthorized persons will not be able to read its contents.

Gpg (Gnu Privacy Guard) is an open source command line tool for encryption and decryption, in this article we go over how to generate and revoke a key, sharing or importing this generated key and the encryption and decryption of files.
