Re: Calculate MD5 Hash for Stream File

Thanks, Scott. Lots of good info there.

I actually found out that they needed a SHA1 Hash instead... (their
documentation stinks).

I did get it working using openssl sha1 file > output and reading it... I
will look into the API, though, but this is pretty simple and this
particular customer does/should have the open source option installed. If
not, I'll just tell them to install it.

Brad,

If you're doing this from CL, I'd suggest writing it to a data area via
the QShell "datarea" command -- its just easier to read a data area in
CL vs. a file.

If you are going to code the logic to read a stream file, then I don't
see why you'd muck about with calling a command like 'md5sum' or
'openssl', instead just read the original stream file and run it through
an API like QC3CALHA to get the md5. That eliminates the dependency on
QShell, PASE and a 3rd party tool like openssl/md5sum being installed.

anything new in the realm of generating an MD5 hash for a stream file in
the IFS?

It looks like openssl may be the easiest... then just output the data to

a

stream file and read it in?

Wanted to make sure there weren't any SQL functions that may make it

easier

and avoid needing to read in and parse a stream file.
