While z/OS platform software packages from IBM are not signed, both the
Internet and DVD options do use SHA-1 to check data integrity because,
as I think most here know, neither TCP/IP transport nor DVD provide
inherent data integrity checking. The probability of undetected data
corruption across this checking, while nonzero, is quite low.

Digitally signing software is pretty common on other platforms - and I
think is at least possible on z/OS.
