CkPkcs5Pbkd2Params() public method

Initializes a new instance of the CkPkcs5Pbkd2Params class.

public CkPkcs5Pbkd2Params ( ulong saltSource, byte saltSourceData, ulong iterations, ulong prf, byte prfData, byte password ) : System
saltSource	ulong	Source of the salt value (CKZ)
saltSourceData	byte	Data used as the input for the salt source
iterations	ulong	Number of iterations to perform when generating each block of random data
prf	ulong	Pseudo-random function to used to generate the key (CKP)
prfData	byte	Data used as the input for PRF in addition to the salt value
password	byte	Password to be used in the PBE key generation
return	System
