This PR updates wolfCLU to properly handle X509 name parsing following changes in wolfSSL’s OBJ_sn2nid function behavior. The changes focus on how Distinguished Name (DN) components are processed when creating X509 certificates. These changes ensure wolfCLU properly handles X509 name components when interfacing with wolfSSL’s updated OBJ_sn2nid implementation. Users working with X509 certificates through wolfCLU […]
