Known Direct Subclasses

This class was deprecated in API level 1.
This class is no longer used. Its functionality has been replaced by java.security.KeyStore, the java.security.cert package, and java.security.Principal.

This class represents identities: real-world objects such as people, companies or organizations whose identities can be authenticated using their public keys. Identities may also be more abstract (or concrete) constructs, such as daemon threads or smart cards.

All Identity objects have a name and a public key. Names are immutable. Identities may also be scoped. That is, if an Identity is specified to have a particular scope, then the name and public key of the Identity are unique within that scope.

An Identity also has a set of certificates (all certifying its own public key). The Principal names specified in these certificates need not be the same, only the key.

An Identity can be subclassed, to include postal and email addresses, telephone numbers, images of faces and logos, and so on.

Public constructors

Identity

Added in API level 1

Identity (String name, 
                IdentityScope scope)

Constructs an identity with the specified name and scope.

Parameters
`name`	`String`: the identity name.
`scope`	`IdentityScope`: the scope of the identity.

Throws
`KeyManagementException`	if there is already an identity with the same name in the scope.

Identity

Added in API level 1

Identity (String name)

Constructs an identity with the specified name and no scope.

Parameters
`name`	`String`: the identity name.

Protected constructors

Identity

Added in API level 1

Identity ()

Constructor for serialization only.

Public methods

addCertificate

Added in API level 1

void addCertificate (Certificate certificate)

Adds a certificate for this identity. If the identity has a public key, the public key in the certificate must be the same, and if the identity does not have a public key, the identity's public key is set to be that specified in the certificate.

First, if there is a security manager, its checkSecurityAccess method is called with "addIdentityCertificate" as its argument to see if it's ok to add a certificate.

Parameters
`certificate`	`Certificate`: the certificate to be added.

Throws
`KeyManagementException`	if the certificate is not valid, if the public key in the certificate being added conflicts with this identity's public key, or if another exception occurs.
`SecurityException`	if a security manager exists and its `checkSecurityAccess` method doesn't allow adding a certificate.

See also:

checkSecurityAccess(String)

certificates

Added in API level 1

Certificate[] certificates ()

Returns a copy of all the certificates for this identity.

Returns
`Certificate[]`	a copy of all the certificates for this identity.

equals

Added in API level 1

boolean equals (Object identity)

Tests for equality between the specified object and this identity. This first tests to see if the entities actually refer to the same object, in which case it returns true. Next, it checks to see if the entities have the same name and the same scope. If they do, the method returns true. Otherwise, it calls identityEquals, which subclasses should override.

Parameters
`identity`	`Object`: the object to test for equality with this identity.

Returns
`boolean`	true if the objects are considered equal, false otherwise.

See also:

identityEquals(Identity)

getInfo

Added in API level 1

String getInfo ()

Returns general information previously specified for this identity.

Returns
`String`	general information about this identity.

See also:

setInfo(String)

getName

Added in API level 1

String getName ()

Returns this identity's name.

Returns
`String`	the name of this identity.

getPublicKey

Added in API level 1

PublicKey getPublicKey ()

Returns this identity's public key.

Returns
`PublicKey`	the public key for this identity.

IdentityScope getScope ()

Returns this identity's scope.

Returns
`int`	a hashcode for this identity.

removeCertificate

Added in API level 1

void removeCertificate (Certificate certificate)

First, if there is a security manager, its checkSecurityAccess method is called with "removeIdentityCertificate" as its argument to see if it's ok to remove a certificate.

Parameters
`certificate`	`Certificate`: the certificate to be removed.

Throws
`KeyManagementException`	if the certificate is missing, or if another exception occurs.

setInfo

Added in API level 1

void setInfo (String info)

Specifies a general information string for this identity.

First, if there is a security manager, its checkSecurityAccess method is called with "setIdentityInfo" as its argument to see if it's ok to specify the information string.

Parameters
`info`	`String`: the information string.

Throws
`SecurityException`	if a security manager exists and its `checkSecurityAccess` method doesn't allow setting the information string.

See also:

setPublicKey

Added in API level 1

void setPublicKey (PublicKey key)

Sets this identity's public key. The old key and all of this identity's certificates are removed by this operation.

First, if there is a security manager, its checkSecurityAccess method is called with "setIdentityPublicKey" as its argument to see if it's ok to set the public key.

Parameters

Returns
`String`	information about this identity, such as its name and the name of its scope (if any).

Throws
`SecurityException`	if a security manager exists and its `checkSecurityAccess` method doesn't allow returning a string describing this identity.
