oclHashcat-lite : New Feature : Zero-length password hashes
This is just a simple skip if the hash is known as "empty". For example:
  • MD5: d41d8cd98f00b204e9800998ecf8427e
  • SHA1: da39a3ee5e6b4b0d3255bfef95601890afd80709
  • LM: aad3b435b51404ee

These hashes were uncrackable for oclHashcat-lite in the past. Nearly all hash-types are support. With one restriction. If its a salted hash-type, this works only for these hash-types that allow empty salts. There are also plans to add these, but this requires to add some 3rd party library. Polarssl would be a good choice since its well written and the license is compatible...
