Genproxy - create GSI proxy credentials with just OpenSSL and a POSIX compatible shell

The genproxy script can be used to generate a GSI proxy credential (GPC) just like grid-proxy-init. But this script:

• is written as a POSIX shell script
• uses only OpenSSL commands to generate a proxy
• uses none of the Globus Toolkit itself
• is tested to work on GNU/Linux, OpenBSD and NetBSD

Usage is as follows:

$ ./genproxy --help
genproxy version 2.1
This script will generate a GSI proxy credential pretty much like globus' grid-proxy-init
