javax.crypto.spec.RC5ParameterSpec — clojure-interop/javax.crypto 1.0.2

This class specifies the parameters used with the RC5 algorithm.

The parameters consist of a version number, a rounds count, a word size, and optionally an initialization vector (IV) (only in feedback mode).

This class can be used to initialize a Cipher object that implements the RC5 algorithm as supplied by RSA Security Inc., or any parties authorized by RSA Security.

->rc-5-parameter-spec clj

(->rc-5-parameter-spec version rounds word-size)

(->rc-5-parameter-spec version rounds word-size iv)

(->rc-5-parameter-spec version rounds word-size iv offset)

Constructor.

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.

version - the version. - int rounds - the number of rounds. - int word-size - the word size in bits. - int iv - 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. - byte[] offset - the offset in iv where the IV starts. - int

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

equals clj

(equals this obj)

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.)

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-iv clj

(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[]

get-rounds clj

(get-rounds this)

Returns the number of rounds.

returns: the number of rounds. - int

get-version clj

(get-version this)

Returns the version.

returns: the version. - int

get-word-size clj

(get-word-size this)

Returns the word size in bits.

returns: the word size in bits. - int

hash-code clj

(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
