public static Java.Security.Signature? GetInstance (string? algorithm);
[<Android.Runtime.Register("getInstance", "(Ljava/lang/String;)Ljava/security/Signature;", "")>]
static member GetInstance : string -> Java.Security.Signature
Parameters
- algorithm
- String
the standard name of the algorithm requested. See the Signature section in the Java Cryptography Architecture Standard Algorithm Name Documentation for information about standard algorithm names.
Returns
the new Signature object.
- Attributes
Exceptions
if the specified algorithm is not available.
if algorithm
is null
.
Remarks
Returns a Signature object that implements the specified signature algorithm.
This method traverses the list of registered security Providers, starting with the most preferred Provider. A new Signature object encapsulating the SignatureSpi 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.
