Hi Albert,

There was a bug in calculating the size of signature that has been fixed
right before releasing 4.10.0:

Cheers,
Michal

Subject: signed hash 4.9.1 4.10.0


Hello,


I am testing the 4.10 client against the current implementation of dCache, and have found the following (xrdcp491 and xrdcp410 are small bash wrappers that point to different xrootd installations and ensure the LD_LIBRARY_PATH is correct.


[arossi@otfrid ~]$ xrdcp491 /etc/fstab root://fndcatemp1.fnal.gov:1094//pnfs/fs/usr/test/arossi/volatile/fstabwith491-test
[574B/574B][100%][==================================================][574B/s]


[arossi@otfrid ~]$ xrdcp410 /etc/fstab root://fndcatemp1.fnal.gov:1094//pnfs/fs/usr/test/arossi/volatile/fstabwith410-test
[0B/0B][100%][==================================================][0B/s]
Run: [ERROR] Server responded with an error: [4003] signed hash verification: received hash length does not match generated hash.



Has the signed hash implementation in the client changed between 4.9 and 4.10?


Thanks,  Al
