UEFI shell hash tools?

UEFI shell hash tools?

[Jeff Westfahl]

Hello all,

I'm looking for tools that run in the UEFI shell and do typical hash functions on files. Basically the UEFI shell equivalent of md5sum, sha1sum, sha256sum, etc. It seems like these tools would be pretty useful, and that they should already exist, but I haven't found anything. Perhaps my google-foo is weak.

Does anybody know of any such tools?

Thank you,

Jeff Westfahl

I've never seen such tools for uefi but you could probably easily
implement them using CryptoPkg's openssl lib.

Thanks
Michael

CPython for UEFI implements the hashlib module from the Python std
library, so you could also search for Python solutions, not just C.

 Ah yes, very nice. I got a prebuilt Python 2.7.2 from ChipSec.

Thanks for the hint!
