irods checksum

[Daniel Hanlon]

Dear all,

I need to check the integrity of some files that have already been copied to irods.

All data in our irods is checksummed with sha2 and I'm trying to work out exactly what encoding is given with an ils -L so that I can compare with a command line utility on another machine. I wondered whether anybody else has managed this?

Many thanks,

Daniel.

The value reported by ils -L for a sha2 checksum is the base64 encoded sha256 checksum.

You should be able to replicate it on the command line with:

sha256sum ${FILENAME} | xxd -r -p | base64

Please let us know if you have any issues with this.

Hi Ben,

Great - just what I needed. I tied various things but was missing the xxd

Many thanks,

Daniel.

Could we have this added to a ‘tips and tricks’ section on the documentation, please?
