  • Constructor Details

    • RC2ParameterSpec

      public RC2ParameterSpec​(int effectiveKeyBits)
      Creates a new RC2ParameterSpec instance with the specified effective key length (in bits),
      Parameters:
      effectiveKeyBits - the effective key length (in bits).

    • RC2ParameterSpec

      public RC2ParameterSpec​(int effectiveKeyBits, byte[] iv)
      Creates a new RC2ParameterSpec instance with the specified effective key length (in bits) and initialization vector.

      The size of the initialization vector must be at least 8 bytes which are copied to protect them against modification.

      Parameters:
      effectiveKeyBits - the effective key length (in bits).
      iv - the initialization vector.
      Throws:
      IllegalArgumentException - if the initialization vector is null or shorter than 8 bytes.

    • RC2ParameterSpec

      public RC2ParameterSpec​(int effectiveKeyBits, byte[] iv, int offset)
      Creates a new RC2ParameterSpec instance with the specified effective key length (in bits) and initialization vector.

      The size of the initialization vector starting at offset must be at least 8 bytes which are copied to protect them against modification.

      Parameters:
      effectiveKeyBits - the effective key length (in bits).
      iv - the initialization vector.
      offset - the offset in the initialization vector to start at.
      Throws:
      IllegalArgumentException - if the initialization vector is null or starting at offset is shorter than 8 bytes.
