GnuPG is a complete and free implementation of the OpenPGP standard asdefined by RFC4880 (also known as PGP). GnuPG allows you to encrypt andsign your data and communications; it features a versatile key managementsystem, along with access modules for all kinds of public keydirectories. GnuPG, also known as GPG, is a command line tool withfeatures for easy integration with other applications. A wealth offrontend applications and libraries are available. GnuPG alsoprovides support for S/MIME and Secure Shell (ssh).
- Generate an RSA SSH keypair with a 4096 bit private key. Ssh-keygen -t rsa -b 4096 -C 'RSA 4096 bit Keys' Generate an DSA SSH keypair with a 2048 bit private key. Ssh-keygen -t dsa -b 1024 -C 'DSA 1024 bit Keys' Generate an ECDSA SSH keypair with a 521 bit private key. Ssh-keygen -t ecdsa -b 521 -C 'ECDSA 521 bit Keys'.
- And GnuPG asks kind of key. Select RSA and RSA. Please select what kind of key you want: (1) RSA and RSA (default) (2) DSA and Elgamal (3) DSA (sign only) (4) RSA (sign only) Your selection? 1 RSA keys may be between 1024 and 4096 bits long. And select 2048-bit (as Gnuk Token only suppurt this). What keysize do you want? (2048) Requested.
In OpenPGP, 'key rings' are some terminology for 'public and/or private keys encoded in the format described by OpenPGP'. Among the types of keys for which OpenPGP describes a key ring format are RSA keys. There is no fundamental issue which would prevent an OpenPGP implementation from using a RSA private key which is stored in a HSM.
Since its introduction in 1997, GnuPG is Free Software (meaning thatit respects your freedom). It can be freely used, modified anddistributed under the terms of the GNU General Public License .
The current version of GnuPG is 2.2.20. See the downloadpage for other maintained versions.
Gpg4win is a Windows version of GnuPG featuring a context menu tool, acrypto manager, and an Outlook plugin to send and receive standardPGP/MIME mails. The current version of Gpg4win is 3.1.11.
