hashlib and sha384

Show key headers only | View raw

Hi,

while trying to get python-xmlsec in shape for xmlsec1 1.3.11 (which will be a transition, and one needed for openssl 4.0.0) I came about the following

After applying the support patch to 1.3.17 - see ##1138515 - (thanks Alexandre for doing the upgrade in the archive so quick) I get a passing test where it segfaulted before
but

tests/test_xmlsec.py .                                                   [100%]Traceback (most recent call last):

_hashlib.UnsupportedDigestmodError: unsupported hash type sha384

happens. (for both 3.13 and 3.14)

 From what I read in https://docs.python.org/3/library/hashlib.html sha384 should have been supported in python anyways and
xmlsec1s build has
checking for SHA384 support... yes
(if it even matters, python3s _hashlib doesn't use xmlsec..)

Am I missing something obvious?

Any idea on why this could fail?

Regards,

Rene
