KeyPairGenerator.GetInstance Method

Definition

Overloads

GetInstance(String)

Returns a KeyPairGenerator object that generates public/private key pairs for the specified algorithm.

GetInstance(String, Provider)

Returns a KeyPairGenerator object that generates public/private key pairs for the specified algorithm.

GetInstance(String, String)

Returns a KeyPairGenerator object that generates public/private key pairs for the specified algorithm.

GetInstance(String)

Returns a KeyPairGenerator object that generates public/private key pairs for the specified algorithm.

[Android.Runtime.Register("getInstance", "(Ljava/lang/String;)Ljava/security/KeyPairGenerator;", "")]
public static Java.Security.KeyPairGenerator? GetInstance (string? algorithm);

Parameters

algorithm
String

the standard string name of the algorithm. See the KeyPairGenerator section in the Java Security Standard Algorithm Names Specification for information about standard algorithm names.

Returns

the new KeyPairGenerator object

Attributes

Exceptions

if the specified algorithm is not available

if algorithm is null

Remarks

Returns a KeyPairGenerator object that generates public/private key pairs for the specified algorithm.

This method traverses the list of registered security Providers, starting with the most preferred Provider. A new KeyPairGenerator object encapsulating the KeyPairGeneratorSpi 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.

[Android.Runtime.Register("getInstance", "(Ljava/lang/String;Ljava/security/Provider;)Ljava/security/KeyPairGenerator;", "")]
public static Java.Security.KeyPairGenerator? GetInstance (string? algorithm, Java.Security.Provider? provider);

Parameters

algorithm
String

the standard string name of the algorithm. See the KeyPairGenerator section in the Java Security Standard Algorithm Names Specification for information about standard algorithm names.

provider
Provider

the provider.

Returns

the new KeyPairGenerator object

Attributes

Exceptions

if the specified algorithm is not available

if algorithm is null

if provider == null

Remarks

Returns a KeyPairGenerator object that generates public/private key pairs for the specified algorithm.

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