Java Source Code / Java Documentation » Security » Bouncy Castle » org.bouncycastle.crypto.generators   Source Cross Reference   Class Diagram   Java Document (Java Doc)   java.lang.Object    org.bouncycastle.crypto.PBEParametersGenerator       org.bouncycastle.crypto.generators.OpenSSLPBEParametersGenerator OpenSSLPBEParametersGenerator public class OpenSSLPBEParametersGenerator extends PBEParametersGenerator (Code) Generator for PBE derived keys and ivs as usd by OpenSSL. The scheme is a simple extension of PKCS 5 V2.0 Scheme 1 using MD5 with an iteration count of 1. Constructor Summary public   OpenSSLPBEParametersGenerator()      Construct a OpenSSL Parameters generator. Method Summary public  CipherParameters generateDerivedMacParameters(int keySize)      Generate a key parameter for use with a MAC derived from the password, salt, and iteration count we are currently initialised with. public  CipherParameters generateDerivedParameters(int keySize)      Generate a key parameter derived from the password, salt, and iteration count we are currently initialised with. public  CipherParameters generateDerivedParameters(int keySize, int ivSize)      Generate a key with initialisation vector parameter derived from the password, salt, and iteration count we are currently initialised with. public  void init(byte[] password, byte[] salt)      Initialise - note the iteration count for this algorithm is fixed at 1. Constructor Detail OpenSSLPBEParametersGenerator public OpenSSLPBEParametersGenerator()(Code) Construct a OpenSSL Parameters generator. Method Detail generateDerivedMacParameters public CipherParameters generateDerivedMacParameters(int keySize)(Code) Generate a key parameter for use with a MAC derived from the password, salt, and iteration count we are currently initialised with. Parameters:   keySize - the size of the key we want (in bits) a KeyParameter object. exception:   IllegalArgumentException - if the key length larger than the base hash size. generateDerivedParameters public CipherParameters generateDerivedParameters(int keySize)(Code) Generate a key parameter derived from the password, salt, and iteration count we are currently initialised with. Parameters:   keySize - the size of the key we want (in bits) a KeyParameter object. exception:   IllegalArgumentException - if the key length larger than the base hash size. generateDerivedParameters public CipherParameters generateDerivedParameters(int keySize, int ivSize)(Code) Generate a key with initialisation vector parameter derived from the password, salt, and iteration count we are currently initialised with. Parameters:   keySize - the size of the key we want (in bits) Parameters:   ivSize - the size of the iv we want (in bits) a ParametersWithIV object. exception:   IllegalArgumentException - if keySize + ivSize is larger than the base hash size. init public void init(byte[] password, byte[] salt)(Code) Initialise - note the iteration count for this algorithm is fixed at 1. Parameters:   password - password to use. Parameters:   salt - salt to use.
