Signature.GetInstance Method

Definition

Overloads

GetInstance(String)

Returns a Signature object that implements the specified signature algorithm.

GetInstance(String, Provider)

Returns a Signature object that implements the specified signature algorithm.

GetInstance(String, String)

Returns a Signature object that implements the specified signature algorithm.

GetInstance(String)

Returns a Signature object that implements the specified signature algorithm.

[Android.Runtime.Register("getInstance", "(Ljava/lang/String;)Ljava/security/Signature;", "")]
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.

static member GetInstance : string * Java.Security.Provider -> Java.Security.Signature

Parameters

algorithm
String

the name of the algorithm requested. See the Signature section in the Java Cryptography Architecture Standard Algorithm Name Documentation for information about standard algorithm names.

provider
Provider

the provider.

Returns

the new Signature object.

Attributes

Exceptions

if the specified algorithm is not available.

if algorithm is null.

if provider == null

Remarks

Returns a Signature object that implements the specified signature algorithm.

A new Signature object encapsulating the SignatureSpi implementation from the specified Provider object is returned. Note that the specified Provider object does not have to be registered in the provider list.
