Lepton’s crack or LCrack for Windows password auditing
Posted by creining | Filed under Security
Reading a recent thread on the pen-test mailing list about password auditing led me to Lepton’s Crack or LCrack for short which is a free GPL password cracking engine and development workbench. Of course, the old standbys of JtR, rainbow tables (which I wrote about before) and the Windows based Cain & Abel and L0phtCrack ($$$) were mentioned. But I had never heard of LCrack. Browsing the LCrack website, I came across a link to An experiment with Lepton’s Crack. After reading this article, the advantages or unique features of LCrack over other software like Cain & Abel or JtR would have to be the advanced regex support which would be useful for auditing passwords with known conventions or if a partial password is known.
