 ``pysaml2`` requires the binary ``xmlsec1`` (on Debian or Ubuntu you can install it with ``apt-get install xmlsec1``)
 
+When following the requirements.txt from odoo, the cryptography module must not be the latest version, otherwise it is incompatible with pyopenssl 19.
+This is necessary because old cryptography/pyopenssl don't declare minimum supported versions.
+It is possible to use newer version of those libraries, eventually patching the Odoo core to stay compatible.
+As this issue is not related to this module, nothing is enforced at the module level.
