Constructor Details

RC5ParameterSpec

public RC5ParameterSpec(int version,
                        int rounds,
                        int wordSize)
Create RC5 parameters without an IV.
Parameters:
version - The version number.
rounds - The number of rounds.
wordSize - The size of a word, in bits.

RC5ParameterSpec

public RC5ParameterSpec(int version,
                        int rounds,
                        int wordSize,
                        byte[] iv)
Create RC5 parameters with an IV. The bytes in iv in the range [0, 2*(wordSize/8)-1] are used.
Parameters:
version - The version number.
rounds - The number of rounds.
wordSize - The size of a word, in bits.
iv - The IV data.

RC5ParameterSpec

public RC5ParameterSpec(int version,
                        int rounds,
                        int wordSize,
                        byte[] iv,
                        int off)
Create RC5 parameters with an IV. The bytes in iv in the range [off, off+2*(wordSize/8)-1] are used.
Parameters:
version - The version number.
rounds - The number of rounds.
wordSize - The size of a word, in bits.
iv - The IV data.
off - From where in the array the IV starts.
