@adriansev noted that none of the default message digest algorithms are supported out-of-the-box by OpenSSL 3 / RHEL 9. The current code (https://github.com/xrootd/xrootd/blob/master/src/XrdSecgsi/XrdSecProtocolgsi.cc#L161) has set `sha1:md5`. Can we simply update this to `sha256` (remove sha1 and md5)? Don't know when `sha256` was added to OpenSSL (could have been named SSLeay at the time!) but I can't imagine we support clients old enough that they don't have `sha256`. -- Reply to this email directly or view it on GitHub: https://github.com/xrootd/xrootd/issues/2030 You are receiving this because you are subscribed to this thread.
