IJ58398: TRUSTCHK -G DOES NOT SET THE HASH_ALGORITHM

APAR status

• Closed as program error.

Error description

• Attempting to change the hashing algorithm with
  'trustchk -g <new hash algorithm>'produces the
  following errors:

Local fix

Problem summary

• Attempting to change the hashing algorithm with
  'trustchk -g <new hash algorithm>' will fail with errors like:
  
  # trustchk -g SHA512
  trustchk: Hash value calculation failed
  trustchk: Verification of stanza failed:
  /usr/lpp/X11/lib/R7/libXevie.a/64/shr_64.o
  trustchk: Internal Error
  trustchk: Hash value calculation failed
  trustchk: Verification of stanza failed:
  /usr/ccs/lib/libxdsm.a/64/shr_64.o
  

Problem conclusion

• The trustchk command will now appropriately handle 64-bit
  library objects files when changing the hashing algorithm.
