Field Detail

salt

protected byte[] salt

iterationCount

protected int iterationCount

hashAlgorithm

protected java.lang.String hashAlgorithm

hashCharset

protected java.lang.String hashCharset

derivedKey

protected byte[] derivedKey

The derived key is actually only a convenience to store a reference derived key. It is not used during computation.

Constructor Detail

PBKDF2Parameters

public PBKDF2Parameters()

Constructor. Defaults to null for byte arrays, UTF-8 as character set and 1000 for iteration count.

PBKDF2Parameters

public PBKDF2Parameters(java.lang.String hashAlgorithm,
                        java.lang.String hashCharset,

                        int iterationCount)

Constructor.

Parameters:

hashAlgorithm - for example HMacSHA1 or HMacMD5

hashCharset - for example UTF-8

salt - Salt as byte array, may be null (not recommended)

iterationCount - Number of iterations to execute. Recommended value 1000.
