Re: [PHP] help needed with tiger tree hashes

Ah yes! Thanks, I see the problem; I have to switch the 8-byte chunks in
byte-order! (Why is Directconnect doing this...)
Thanks for your help. Greetings, Carl.

  I am trying to generate tiger tree hashes the same way as

  I checked the output from php with the reference vectors from
  http://www.cs.technion.ac.il/~biham...ssie-format.dat
  and they appear to be different!
 
  echo bin2hex(mhash(MHASH_TIGER, 'abc')).br/\n;
  outputs
  f258c1e88414ab2a527ab541ffc5b8bf935f7b951c132951
  instead of
  2AAB1484E8C158F2BFB8C5FF41B57A525129131C957B5F93
 
  and, for example,
  echo bin2hex(mhash(MHASH_TIGER, 'message digest')).br/\n;
  outputs
  951a2078cbf881d91c441e754830cf0df6295aa51aca7f51
  instead of
  D981F8CB78201A950DCF3048751E441C517FCA1AA55A29F6
 
  What am I doing wrong here?
