GnuPG versions before 1.0.0

Not intended for production use.

GnuPG 1.0.0-1.0.1

GnuPG (sometimes called "GPG") is a GNU public-key encryption program that uses the same standards as PGP. GNU is a type of software license that says (essentially) the software is free to use, but if you change the source code, you must make your revisions available to the public. Go to theGNU Project and the Free Software Foundation web site for more information about GNU software in general. GPG is available at the GnuPG web site.

From the distributed source code, GnuPG does not support the use or creation of RSA keys. However, plugins are available that will allow GnuPG to use (but not create) RSA keys.

GnuPG version 1.0.1-1.0.2

• Bugfix releases.

GnuPG version 1.0.3

• Uses built-in RSA code rather than the modules described above. It still does not allow the creation of RSA keys.

GnuPG version 1.0.4

• Fixes a serious bug surrounding multiple signatures in a message.

Note: The released GnuPG 1.0.4 contains two (minor) bugs:

1. Will not create ~/.gnupg directory if it doesn't already exist (workaround: create it yourself).
2. Will warn that AES algorithm is depreciated and to use another (patch available here).
