All known Subclasses:   org.bouncycastle.jce.provider.BrokenJCEBlockCipher,
OldPKCS12ParametersGenerator
class OldPKCS12ParametersGenerator extends PBEParametersGenerator (Code)
Generator for PBE derived keys and ivs as defined by PKCS 12 V1.0, with a bug affecting 180 bit plus keys - this class is only here to allow smooth migration of the version 0 keystore to version 1. Don't use it (it won't be staying around).

The document this implementation is based on can be found at RSA's PKCS12 Page



Field Summary

Constructor Summary
public  OldPKCS12ParametersGenerator(Digest digest)
     Construct a PKCS 12 Parameters generator.

Method Summary
public  CipherParametersgenerateDerivedMacParameters(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  CipherParametersgenerateDerivedParameters(int keySize)
     Generate a key parameter derived from the password, salt, and iteration count we are currently initialised with.
public  CipherParametersgenerateDerivedParameters(int keySize, int ivSize)

Constructor Detail
OldPKCS12ParametersGenerator
public OldPKCS12ParametersGenerator(Digest digest)(Code)
Construct a PKCS 12 Parameters generator. This constructor will accept MD5, SHA1, and RIPEMD160.
Parameters:
  digest - the digest to be used as the source of derived keys.
exception:
  IllegalArgumentException - if an unknown digest is passed in.




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.



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.



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.
