[xz-devel] Disabling CRC/SHA-256 checks on decompression

[Florian Weimer]

Would it be possible to add a flag to disable these checks during 
decompression?  I have data format and lots of data encoded in it (RPMs, 
in case you wonder) which has its own integrity checking, and 
unfortunately, all the existing XZ streams have been built with SHA-256 
hashing.  Being able to disable hashing would result in a nice speed-up 
for me (based on preliminary tests using hand-crafted RPMs).
