Public Constructors

public RC2ParameterSpec (int effectiveKeyBits)

Added in API level 1

Creates a new RC2ParameterSpec instance with the specified effective key length (in bits),

Parameters
effectiveKeyBits the effective key length (in bits).

public RC2ParameterSpec (int effectiveKeyBits, byte[] iv)

Added in API level 1

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.

public RC2ParameterSpec (int effectiveKeyBits, byte[] iv, int offset)

Added in API level 1

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.

Public Methods

public boolean equals (Object obj)

Added in API level 1

Compares the specified object to this RC2ParameterSpec instance.

Parameters
obj the object to compare.
Returns
  • true if the effective key length and the initialization vector of both objects are equal, otherwise false.

public int getEffectiveKeyBits ()

Added in API level 1

Returns the effective key length (in bits).

Returns
  • the effective key length (in bits).

public byte[] getIV ()

Added in API level 1

Returns a copy of the initialization vector.

Returns
  • a copy of the initialization vector, or null if none specified.

public int hashCode ()

Added in API level 1

Returns the hash code of this RC2ParameterSpec instance.

Returns
  • the hash code.
