![]() Message is decrypted, a signature is verified, a file containing keys is listed). Gpg2 may be run with no commands, in which case it will perform a reasonable action depending on the type of file it is given as input (an encrypted Rather reduce the available algorithms to a "PGP-safe" list.Ĭommands are not distinguished from options except for the fact that only one command is allowed. ![]() These options are safe as they do not force any particular algorithms in violation of OpenPGP, but If you absolutely must override the safe default, or if the preferences on a given key are invalid for some reason, you are far better off using the Only override this safe default if you really know what you are doing. GnuPG uses the standard OpenPGP preferences system that will always do the right thing and create messages that are usable by all recipients, regardless of A message using BLOWFISH simply could not be read by a PGP user. Recently, no (unhacked) version of PGP supported the BLOWFISH cipher algorithm. There are dozens of variations of OpenPGP programs available, and each supports a slightly different subset of these optional algorithms. GnuPG, it is possible to create a perfectly valid OpenPGP message, but one that cannot be read by the intended recipient. It is important to be aware that not all OpenPGP programs implement these optionalĪlgorithms and that by forcing their use via the -cipher-algo, -digest-algo, -cert-digest-algo, or -compress-algo options in In particular, GnuPG implements many of the optional parts of the standard, suchĪs the SHA-512 hash, and the ZLIB and BZIP2 compression algorithms. GnuPG tries to be a very flexible implementation of the OpenPGP standard. If you are going to verify detached signatures, make sure that the program knows about it either give both filenames on the command line or use aq-aq to Keep in mind that, if this program is used over a network (telnet), it is *very* easy to spy out your passphrase! Programs to do dictionary attacks on your secret keyring are very easy to write and so you should protect your "~/.gnupg/" directory very well. This passphrase is the weakest part of the whole system. #DMG VS PGP SIGNATURE MEANING PASSWORD#Use a *good* password for your user account and a *good* passphrase to protect your secret key. The program returns 0 if everything was fine, 1 if at least a signature was bad, and other error codes for fatal errors. ![]() Oq gpg.conf-2cq instead of just oq gpg.confcq. If you need to use different configuration files, you should make use of something like #DMG VS PGP SIGNATURE MEANING INSTALL#Possible to install both versions on the same system. The standalone version will be kept maintained and it is Gpg2 and more targeted to the desktop as it requires several other modules to be installed. In contrast to the standalone version gpg, which is more suited for server and embedded platforms, this version is installed under the name gpg2 features complete key management and all bells and whistles you can expect from It is a tool to provideĭigital encryption and signing services using the OpenPGP standard. ![]() Gpg2 is the OpenPGP part of the GNU Privacy Guard (GnuPG). ![]()
