javax.crypto.spec.RC2ParameterSpec
This class specifies the parameters used with the RC2 algorithm.
The parameters consist of an effective key size and optionally an 8-byte initialization vector (IV) (only in feedback mode).
This class can be used to initialize a Cipher object that implements the RC2 algorithm.

->rc-2-parameter-specclj
(->rc-2-parameter-spec effective-key-bits)(->rc-2-parameter-spec effective-key-bits iv)(->rc-2-parameter-spec effective-key-bits iv offset)Constructor.
Constructs a parameter set for RC2 from the given effective key size (in bits) and IV.
The IV is taken from iv, starting at offset inclusive. The bytes that constitute the IV are those between iv[offset] and iv[offset+7] inclusive.
effective-key-bits - the effective key size in bits. - int
iv - the buffer with the IV. The first 8 bytes of the buffer beginning at offset inclusive are copied to protect against subsequent modification. - byte[]
offset - the offset in iv where the 8-byte IV starts. - int
throws: java.lang.IllegalArgumentException - if iv is null.
Constructor. Constructs a parameter set for RC2 from the given effective key size (in bits) and IV. The IV is taken from iv, starting at offset inclusive. The bytes that constitute the IV are those between iv[offset] and iv[offset+7] inclusive. effective-key-bits - the effective key size in bits. - `int` iv - the buffer with the IV. The first 8 bytes of the buffer beginning at offset inclusive are copied to protect against subsequent modification. - `byte[]` offset - the offset in iv where the 8-byte IV starts. - `int` throws: java.lang.IllegalArgumentException - if iv is null.
equalsclj
(equals this obj)Tests for equality between the specified object and this object. Two RC2ParameterSpec objects are considered equal if their effective key sizes and IVs are equal. (Two IV references are considered equal if both are null.)
obj - the object to test for equality with this object. - java.lang.Object
returns: true if the objects are considered equal, false if
obj is null or otherwise. - boolean
Tests for equality between the specified object and this object. Two RC2ParameterSpec objects are considered equal if their effective key sizes and IVs are equal. (Two IV references are considered equal if both are null.) obj - the object to test for equality with this object. - `java.lang.Object` returns: true if the objects are considered equal, false if obj is null or otherwise. - `boolean`
get-effective-key-bitsclj
(get-effective-key-bits this)Returns the effective key size in bits.
returns: the effective key size in bits. - int
Returns the effective key size in bits. returns: the effective key size in bits. - `int`
get-ivclj
(get-iv this)Returns the IV or null if this parameter set does not contain an IV.
returns: the IV or null if this parameter set does not contain an IV.
Returns a new array each time this method is called. - byte[]
Returns the IV or null if this parameter set does not contain an IV. returns: the IV or null if this parameter set does not contain an IV. Returns a new array each time this method is called. - `byte[]`
hash-codeclj
(hash-code this)Calculates a hash code value for the object. Objects that are equal will also have the same hashcode.
returns: a hash code value for this object. - int
Calculates a hash code value for the object. Objects that are equal will also have the same hashcode. returns: a hash code value for this object. - `int`
