New submission from Ralph Broenink:
Issue #18138 added support for the cadata argument in
SSLContext.load_verify_locations. However, this argument does not support
certificate revocation lists (CRLs) to be added (at least not in PEM format):
ssl.SSLError: [PEM: NO_START_LINE] no start line (_ssl.c:2633)
The documentation of this method is rather vague on this subject and does not
state explicitly this is not allowed:
This method can also load certification revocation lists (CRLs) in PEM or
or DER format. In order to make use of CRLs, SSLContext.verify_flags must be
configured properly.
I think CRLs should be allowed to be loaded using the cadata argument. However,
the documentation could use some polishing too: "At least one of cafile or
capath must be specified." is outdated since the introduction of cadata.
