Detailed Description

Helper Class for dealing with the secure hashing of passwords in OpenPetra.

OpenPetra supports different versions of password hashing algorithms; these are implemented in the Classes that implement the IPasswordHashingScheme Interface!

Member Function Documentation

EqualsAntiTimingAttack()

static bool Ict.Common.TPasswordHelper.EqualsAntiTimingAttack ( byte[]  a, byte[]  b  )

inlinestatic
