The IBM® Global Security Kit (GSKit) installation must be performed as the user root.
The GSKit install media must be accessible to the installation programs. Although the SMIT program can access the install media via a read-only device (such as a CD-ROM), the best method is to copy the GSKit media to the local file system first. A good place for this is /var/spool/pkg or alternatively /tmp/gsk8.
zcat package.tar.Z | tar -xf -
zcat gskcrypt64-8.0.13.aix.ppc.tar.Z | tar -xf -
For GSKit Crypt 64-bit GSKit8.gskcrypt64.ppc.rte would be the decompressed file. The installation instructions assume that you have decompressed the installation packages and are working with them directly.
