GetInstance(String)
Returns a Mac
object that implements the
specified MAC algorithm.
[Android.Runtime.Register("getInstance", "(Ljava/lang/String;)Ljavax/crypto/Mac;", "")]
public static Javax.Crypto.Mac? GetInstance (string? algorithm);
[<Android.Runtime.Register("getInstance", "(Ljava/lang/String;)Ljavax/crypto/Mac;", "")>]
static member GetInstance : string -> Javax.Crypto.Mac
Parameters
- algorithm
- String
the standard name of the requested MAC algorithm. See the Mac section in the Java Cryptography Architecture Standard Algorithm Name Documentation for information about standard algorithm names.
Returns
the new Mac
object.
- Attributes
Exceptions
if the specified algorithm is not available by any provider.
if algorithm
is null
(instead of
NoSuchAlgorithmException as in 1.4 release).
Remarks
Returns a Mac
object that implements the specified MAC algorithm.
This method traverses the list of registered security Providers, starting with the most preferred Provider. A new Mac object encapsulating the MacSpi implementation from the first Provider that supports the specified algorithm is returned.
Note that the list of registered providers may be retrieved via the Security#getProviders() Security.getProviders()
method.

Remarks
Returns a Mac
object that implements the specified MAC algorithm.
A new Mac object encapsulating the MacSpi implementation from the specified Provider object is returned. Note that the specified Provider object does not have to be registered in the provider list.
