Method Detail

encryptShortString

public static final java.lang.String encryptShortString(java.lang.String short_string)

Encrypts a short String (password) using the two first characters as salt. Afterwards chops off the salt - (hopefully) making this a one-way encryption scheme.

compareShortString

public static final boolean compareShortString(java.lang.String password,
                                               java.lang.String encrypted)

Compares an encrypted String to the clear text equivalent.

encryptMediumString

public static final java.lang.String encryptMediumString(java.lang.String medium_string)

Encrypts a medium short String by chopping it up in multiples of eight characters, using the two first characters in each block as salt. Afterwards chops off the salt - (hopefully) making this a one-way encryption scheme. This is propably a very cumbersome way of doing it.

compareMediumString

public static final boolean compareMediumString(java.lang.String password,
                                                java.lang.String encrypted)

Compares an encrypted String to the clear text equivalent.
