KeyIV Property
The initialization vector (IV) of a symmetric key.
Syntax
symmetriccrypto.getKeyIV([callback]) symmetriccrypto.setKeyIV( keyIV_Buffer, [callback])
Callback
The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).
The callback for the getKeyIV([callback]) method is defined as:
function(err, buffer){ }
'err' is the error that occurred. If there was no error, then 'err' is 'null'.
'buffer' is the value returned by the method.
The callback for the setKeyIV([callback]) method is defined as:
function(err){ }
'err' is the error that occurred. If there was no error, then 'err' is 'null'.
'err' has 2 properties which hold detailed information:
err.code err.message
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.
This property is not available at design time.
