Hmm, maybe *that* is the problem. edk2 has its own crypto algo provider (CryptoPkg/Library/OpensslLib/OpensslStub/uefiprov.c) offering a limited set of ciphers to reduce the size of OpensslLib. This was added with the switch to openssl-3. > ... I wonder how TlsCipherMappingTable looks in Project Mu! mu_basecore (release/202302 which seems to be latest but doesn't include the openssl-3 switch) is identical to upstream edk2. take care, Gerd -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
