**
** The code here implements a version of the SHA1 hash function that
** is not vulnerable to crypto-analysis based attacks.  If an input
** is detected that looks like it might have been the result of a
** crypto-analysis attack, then the hash is perturbed to generate a
** completely different hash.  The authors claim that the chance of
** a false-positive is vanishingly small.

** this file was generated by the 'parse_bitrel' program in the tools section
** using the data files from directory 'tools/data/3565'
**
** sha1_dvs contains a list of SHA-1 Disturbance Vectors (DV) to check
** dvType, dvK and dvB define the DV: I(K,B) or II(K,B) (see the paper)
** dm[80] is the expanded message block XOR-difference defined by the DV
** testt is the step to do the recompression from for collision detection
** maski and maskb define the bit to check for each DV in the dvmask returned by ubc_check
**
** ubc_check takes as input an expanded message block and verifies the unavoidable bitconditions for all listed DVs
** it returns a dvmask where each bit belonging to a DV is set if all unavoidable bitconditions for that DV have been met
** thus one needs to do the recompression check for each DV that has its bit set
**
** ubc_check is programmatically generated and the unavoidable bitconditions have been hardcoded
** a directly verifiable version named ubc_check_verify can be found in ubc_check_verify.c
** ubc_check has been verified against ubc_check_verify using the 'ubc_check_test' program in the tools section
