[tboot-devel] extra bytes printed after SHA1 hash?

[Timo L. <tim...@ik...>]

Hi,

when I boot current mercurial tip with TPM 1.2 I get the following output:

TBOOT: verifying policy 
TBOOT: verifying module "root=UUID=bc701bae-ee9c-4151-a85b-0f5a68212975 ro quiet net.ifnames=0 intel_iommu=on"...
TBOOT:   OK : 26 0d 8e 28 3d 24 8b 45 74 92 02 76 50 f4 28 11 2b 6c d5 03 00 00 00 00 00 00 00 00 00 00 d8 9b
TBOOT: verifying module ""...
TBOOT:   OK : ed 04 ea fe e3 e4 30 63 ae c2 ba 41 cc 35 de aa f0 2a e7 18 00 00 00 00 00 00 00 00 00 00 d8 9b
TBOOT: all modules are verified

Notice how both hashes end with the same byte string "00 00 00 00 00 00 00 
00 00 00 d8 9b". Is the code printing 32 bytes of memory (length of a 
SHA256 hash) but the memory actually contains a SHA1 hash?
