Re: Program to Calculate Hash using SHA-256 of a file

Hello,

at V5R2 CIPHER MI instruction does not support SHA-256 (only SHA-1)
QC3* API were only introduced at V5R3...

I could be wrong but for me at V5R2, it is a real challenge.
One option would be to download the C open source version (that supports
right endian versions) and compile it on your system... (if you have
the C compiler...)
not easy but do-able...
another option would be to use java but at V5R2... iI think the the JVM
is limited to 1.4 so would require to install the correct version of
bouncy castle jar.. (another challenge... )

I use:

DCipher PR EXTPROC('_CIPHER')
D * VALUE
D * VALUE
D * VALUE

But I do not remember where is the documentation, Scot has a complete
sample at: https://archive.midrange.com/midrange-l/200006/msg01334.html

Hi all

I'm looking for an example how to calculate Hash using SHA-256 . be

patient

for my request : this should be run on V5R2m0 (it would be possible)

I found this old link

https://www.experts-exchange.com/questions/20502110/Need-to-call-MD5-algorit

hm-from-RPGLE.html, but i don't know how to (if possible) adapt to

SHA-256

Thanks in in advance
