Constructor Details

RC2ParameterSpec

public RC2ParameterSpec(int effectiveKeyBits)
Create RC2 parameters without an IV.
Parameters:
effectiveKeyBits - The number of effective key bits.

                        byte[] iv)
Create RC2 parameters with an IV.
Parameters:
effectiveKeyBits - The number of effective key bits.
iv - The IV; the first eight bytes of this array are used.

RC2ParameterSpec

public RC2ParameterSpec(int effectiveKeyBits,
                        byte[] iv,
                        int offset)
Create RC2 parameters with an IV.
Parameters:
effectiveKeyBits - The number of effective key bits.
iv - The IV; the first eight bytes of this array after offset are used.
