sha1sum has been upgraded to 5.2.1 in the sipb locker. It
will be visible after the next regular release of the sipb
locker. The main change between 5.2.1 and the 4.5.3 is that
--check accepts BSD-style signatures.
sha1sum computes or checks SHA1 (160-bit) checksums. Its
command line invocation is identical to md5sum.
(Incidentally, recently Xiaoyun Wang, et al. have developed
a method of producing MD5 collisions.)
This software is installed only for the Solaris platform,
because sha1sum is already present locally in the Athena
Linux distribution.
The SHA1 checksum can also be calculated with "openssl sha1"
or "gpg --print-md sha1".
