Definition

Overloads

GetInstance(String, Provider)

Returns a MessageDigest object that implements the specified digest algorithm.

GetInstance(String, String)

Returns a MessageDigest object that implements the specified digest algorithm.

GetInstance(String)

Returns a MessageDigest object that implements the specified digest algorithm.

GetInstance(String, Provider)

Returns a MessageDigest object that implements the specified digest algorithm.

[Android.Runtime.Register("getInstance", "(Ljava/lang/String;Ljava/security/Provider;)Ljava/security/MessageDigest;", "")]
public static Java.Security.MessageDigest GetInstance (string algorithm, Java.Security.Provider provider);
[<Android.Runtime.Register("getInstance", "(Ljava/lang/String;Ljava/security/Provider;)Ljava/security/MessageDigest;", "")>]
static member GetInstance : string * Java.Security.Provider -> Java.Security.MessageDigest

Parameters

algorithm
String

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

provider
Provider

the provider.

Returns

a MessageDigest object that implements the specified algorithm

Attributes

Exceptions

if the specified algorithm is not available

if algorithm is null

if provider == null

Remarks

Returns a MessageDigest object that implements the specified digest algorithm.

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

GetInstance(String, String)

Returns a MessageDigest object that implements the specified digest algorithm.

[Android.Runtime.Register("getInstance", "(Ljava/lang/String;Ljava/lang/String;)Ljava/security/MessageDigest;", "")]
public static Java.Security.MessageDigest GetInstance (string algorithm, string provider);
[<Android.Runtime.Register("getInstance", "(Ljava/lang/String;Ljava/lang/String;)Ljava/security/MessageDigest;", "")>]
static member GetInstance : string * string -> Java.Security.MessageDigest

Parameters

algorithm
String

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

provider
String

the name of the provider.

Returns

a MessageDigest object that implements the specified algorithm

Attributes

Exceptions

if the specified algorithm is not available

if the specified provider is not available

if algorithm is null

if provider == null || provider.isEmpty()

Remarks

Returns a MessageDigest object that implements the specified digest algorithm.

A new MessageDigest object encapsulating the MessageDigestSpi implementation from the specified provider is returned. The specified provider must be registered in the security provider list.

Note that the list of registered providers may be retrieved via the Security#getProviders() Security.getProviders() method.

static member GetInstance : string -> Java.Security.MessageDigest

Parameters

algorithm
String

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

Returns

a MessageDigest object that implements the specified algorithm

Attributes

Exceptions

if the specified algorithm is not available

if algorithm is null

Remarks

Returns a MessageDigest object that implements the specified digest algorithm.

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