RC5ParameterSpec	back to summary
public RC5ParameterSpec(int version, int rounds, int wordSize, byte[] iv) Constructs a parameter set for RC5 from the given version, number of rounds, word size (in bits), and IV. Note that the size of the IV (block size) must be twice the word size. The bytes that constitute the IV are those between `iv[0]` and `iv[2(wordSize/8)-1]` inclusive. Parameters version:int the version. rounds:int the number of rounds. wordSize:int the word size in bits. iv:byte[] the buffer with the IV. The first `2(wordSize/8)` bytes of the buffer are copied to protect against subsequent modification. Exceptions IllegalArgumentException: if `iv` is `null` or `(iv.length < 2 * (wordSize / 8))`

public RC5ParameterSpec(int version, int rounds, int wordSize, byte[] iv)

Constructs a parameter set for RC5 from the given version, number of rounds, word size (in bits), and IV.

Note that the size of the IV (block size) must be twice the word size. The bytes that constitute the IV are those between iv[0] and iv[2*(wordSize/8)-1] inclusive.

Parameters

version:int: the version.
rounds:int: the number of rounds.
wordSize:int: the word size in bits.
iv:byte[]: the buffer with the IV. The first 2*(wordSize/8) bytes of the buffer are copied to protect against subsequent modification.

Exceptions

IllegalArgumentException:: if iv is null or (iv.length < 2 * (wordSize / 8))

RC5ParameterSpec	back to summary
public RC5ParameterSpec(int version, int rounds, int wordSize, byte[] iv, int offset) Constructs a parameter set for RC5 from the given version, number of rounds, word size (in bits), and IV. The IV is taken from `iv`, starting at `offset` inclusive. Note that the size of the IV (block size), starting at `offset` inclusive, must be twice the word size. The bytes that constitute the IV are those between `iv[offset]` and `iv[offset+2(wordSize/8)-1]` inclusive. Parameters version:int the version. rounds:int the number of rounds. wordSize:int the word size in bits. iv:byte[] the buffer with the IV. The first `2(wordSize/8)` bytes of the buffer beginning at `offset` inclusive are copied to protect against subsequent modification. offset:int the offset in `iv` where the IV starts. Exceptions IllegalArgumentException: if `iv` is `null` or `(iv.length - offset < 2 * (wordSize / 8))`

public RC5ParameterSpec(int version, int rounds, int wordSize, byte[] iv, int offset)

Constructs a parameter set for RC5 from the given version, number of rounds, word size (in bits), and IV.

The IV is taken from iv, starting at offset inclusive. Note that the size of the IV (block size), starting at offset inclusive, must be twice the word size. The bytes that constitute the IV are those between iv[offset] and iv[offset+2*(wordSize/8)-1] inclusive.

Parameters

version:int: the version.
rounds:int: the number of rounds.
wordSize:int: the word size in bits.
iv:byte[]: the buffer with the IV. The first 2*(wordSize/8) bytes of the buffer beginning at offset inclusive are copied to protect against subsequent modification.
offset:int: the offset in iv where the IV starts.

Exceptions

IllegalArgumentException:: if iv is null or (iv.length - offset < 2 * (wordSize / 8))

Method Detail

equals back to summary

equals	back to summary
public boolean equals(Object obj) Overrides java.lang.Object.equals. Tests for equality between the specified object and this object. Two RC5ParameterSpec objects are considered equal if their version numbers, number of rounds, word sizes, and IVs are equal. (Two IV references are considered equal if both are `null`.) Parameters obj:Object the object to test for equality with this object. Returns:boolean true if the objects are considered equal, false if `obj` is null or otherwise. Annotations @Override

public boolean equals(Object obj)

Overrides java.lang.Object.equals.

Tests for equality between the specified object and this object. Two RC5ParameterSpec objects are considered equal if their version numbers, number of rounds, word sizes, and IVs are equal. (Two IV references are considered equal if both are null.)

Parameters

obj:Object: the object to test for equality with this object.

Returns:boolean

true if the objects are considered equal, false if obj is null or otherwise.
