IvParameterSpec

open class IvParameterSpec : AlgorithmParameterSpec
kotlin.Any
   ↳ javax.crypto.spec.IvParameterSpec

This class specifies an initialization vector (IV). Examples which use IVs are ciphers in feedback mode, e.g., DES in CBC mode and RSA ciphers with OAEP encoding operation.

Summary

Public constructors

Creates an IvParameterSpec object using the bytes in iv as the IV.
IvParameterSpec(iv: ByteArray!, offset: Int, len: Int)

Creates an IvParameterSpec object using the first len bytes in iv, beginning at offset inclusive, as the IV.
Public methods
open ByteArray!

Returns the initialization vector (IV).

Public constructors

IvParameterSpec

Added in API level 1
IvParameterSpec(iv: ByteArray!)

Creates an IvParameterSpec object using the bytes in iv as the IV.

Parameters
iv ByteArray!: the buffer with the IV. The contents of the buffer are copied to protect against subsequent modification.
Exceptions
java.lang.NullPointerException if iv is null

IvParameterSpec

Added in API level 1
IvParameterSpec(
    iv: ByteArray!, 
    offset: Int, 
    len: Int)

Creates an IvParameterSpec object using the first len bytes in iv, beginning at offset inclusive, as the IV.

The bytes that constitute the IV are those between iv[offset] and iv[offset+len-1] inclusive.

Parameters
iv ByteArray!: the buffer with the IV. The first len 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.
len Int: the number of IV bytes.
Exceptions
java.lang.IllegalArgumentException if iv is null or (iv.length - offset < len)
java.lang.ArrayIndexOutOfBoundsException is thrown if offset or len index bytes outside the iv.

Public methods

getIV

Added in API level 1
open fun getIV(): ByteArray!

Returns the initialization vector (IV).

Return
ByteArray! the initialization vector (IV). Returns a new array each time this method is called.
