keyIV (property)
The initialization vector (IV) of a symmetric key.
Syntax
- (NSData*)keyIV:(int)keyIndex;
public func keyIV(keyIndex: Int32) throws -> Data
Remarks
The initialization vector (IV) of a symmetric key. This is normally a public part of a symmetric key, the idea of which is to introduce randomness to the encrypted dataand/or serve as a first block in chaining ciphers.
The KeyIndex parameter specifies the index of the item in the array. The size of the array is controlled by the KeyCount property.
This property is read-only.
