Method Detail

getMaxSCryptAlgo

public static HashAlgorithm getMaxSCryptAlgo()

Returns a SCrypt generator that uses 2^20 iterations, r=8, p=1 and dkLen = 32

Returns:

an instance of HashAlgorithm that supports strong SCrypt hashing

getSCryptAlgo

public static HashAlgorithm getSCryptAlgo(int iterations)

Returns a SCrypt generator that uses 2^20 iterations, r=8, p=1 and dkLen = 32

Parameters:

iterations - the number of iterations to use. Must be >= 2^14

Returns:

an instance of HashAlgorithm that supports strong SCrypt hashing

getMinSCryptAlgo

public static HashAlgorithm getMinSCryptAlgo()

Returns a SCrypt generator that uses 2^14 iterations, r=8, p=1 and dkLen = 32

Returns:

an instance of HashAlgorithm that supports fast SCrypt hashing, but is not as strong (via iterations)
