You need a user ID to identify your key the software constructs the user IDДЇrom the Real Name, Comment and Email Address in this form:Д®mail address: admin selected this USER-ID:Д¬hange (N )ame, (C )omment, (E )mail or (O )kay / (Q )uit? o Please specify how long the key should be valid.

This keypair is generated with the -gen-key option of gpg: The greatest attention should be given exclusively to the private key, which must remain strictly in the hands of the legitimate owners.ДЄs first thing, you must generate a public/private keypair. The fact that it falls into foreign hands will not constitute any danger. The public key can be distributed to anyone without any control. It will be used to encrypt files addressed to the owner of the certificate, only the owner of the related private key can decrypt that file. The public key can be distributed to the whole world, without incurring in any risk of danger. The owner will use it to decrypt files that are sent to him, that can now be sent also with insecure protocols (email, ftp, http upload) The private key should remain exclusively in the hands of the owner of the certificate. So in the example we will adopt a system that will use a certificate that consists of two distinct keys, one private and one public. Once encrypted with the public key, those files can only be decrypted with the private key. The benefit of public-private key encryption is that you can keep your public key out in the open, and use it from anywhere to encrypt files. There is also another approach to encryption, GPG allows you to use public-private key encryption to encrypt and decrypt files on Windows and Linux. rw-r-r- 1 root root 67 Jan 10 23:14 Solution 2 вЂ“ Encrypt with a public key rw-r-r- 1 root root 12 Jan 10 23:13 mysecretdocument.txt rw-r-r- 1 root root 12 Jan 10 23:37 mynewfile.txt rw-r-r- 1 root root 12 Jan 10 23: 13 mysecretdocument.txt Mint-desktop tmp # ls -l my* -rw-r-r- 1 root root 12 Jan 10 23: 37 mynewfile.txt Mint-desktop tmp # gpg -o mynewfile.txt -d

In this example IвЂ™ll use a simple file, mysecretdocument.txt that contains secret 1234

#How to add another user to encrypted file password

The key, in practice, represent a shared secret between two or more parties that can be used to maintain a private information, in general this solution is as good as the password you choose, can be a good solution to send a document via email and communicate the password with another media (telephone, instant message, chat).

This is the easiest way to encrypt a file, you use a вЂњpasswordвЂќ to encrypt the file and when you want to decrypt the cyphertext you have to give the same password. Solution 1 вЂ“ Encrypt with a simmetric key

This software is frequently integrated with mail client so it can sign, crypt or do both actions on the mail you send and receive, and now weвЂ™ll see how to use it on the command line to encrypt a file. Current versions of PGP (and VeridisвЂ™ Filecrypt) are interoperable with GnuPG and other OpenPGP-compliant systems. GnuPG is compliant with RFC 4880, which is the current IETF standards track specification of OpenPGP. GNU Privacy Guard (GnuPG or GPG) is a GPL Licensed alternative to the PGP suite of cryptographic software. Today i return to the topic of encryption and security and in particular IвЂ™ll show how to simply encrypt a file with GnuPG, this can be really usefull to encrypt a single file where you have your passwords or some personal information that you want to keep safer.
