Syntax

• Objective-C
• Swift

@property (nonatomic,readwrite,assign,getter=cryptoKeyIV,setter=setCryptoKeyIV:) NSData* cryptoKeyIV;
- (NSData*)cryptoKeyIV;
- (void)setCryptoKeyIV:(NSData*)newCryptoKeyIV;

public var cryptoKeyIV: Data {
  get {...}
  set {...}
}

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.
