```Nor is it clear whether the symmetrical encryption part, which dCache would use to sign requests from its third-party client to send to the xrootd server, should be similarly expanded by 16 bytes. And why those bytes, before encryption, should be uniformly 0x10 (i.e., decimal 16).``` I have gone ahead and changed the encryption as well in order to make dCache compatible with the 4.10 server. Seems the same problem does indeed exist symmetrically. I have a patch to restore compatibility, https://github.com/alrossi/xrootd4j/tree/fix/master/dh-signature but it would be good to know why those extra bytes are there. -- You are receiving this because you are subscribed to this thread.
