I usually use a zip archive and a checksum check for that, but whatever 
choreography works for you, have at.

OpenVMS is fairly late to adopting file checksums, but the CHECKSUM 
command does have an only-somewhat-stale SHA-1 checksum support as of 
V8.4.

Or use the checksum support in OpenSSL (openssl dgst -sha256 -binary 
{zipfile}, etc).

...this having gotten burned enough times by BACKUP savesets embedded 
within zip archives. Which are awkward to read and verify, when off of 
OpenVMS...
