Constructor Detail

IAIKPKCS11RsaPublicKey

public IAIKPKCS11RsaPublicKey(TokenManager tokenManager,
                              iaik.pkcs.pkcs11.objects.RSAPublicKey publicKeyObject)

Construct a public key object that is associated with the given publickeyObjecton the given token.

Parameters:

tokenManager - The token manager of the token where this key resides.

publicKeyObject - The PKCS#11 key object.

Preconditions:

(token <> null) and (publicKeyObject <> null)

Method Detail

create

public static IAIKPKCS11RsaPublicKey create(TokenManager tokenManager,
                                            iaik.pkcs.pkcs11.objects.RSAPublicKey publicKeyObject)

Create a new instance of a IAIKPKCS11RsaPublicKey which's token managed by the given token manager and is based on the given PKCS#11 key object.

Parameters:

tokenManager - The token manager of the token where the key is.

publicKeyObject - The PKCS#11 key object.

Returns:

A new IAIKPKCS11RsaPublicKey that can be used with this provider.

Postconditions:

(result <> null)

getPublicExponent

public java.math.BigInteger getPublicExponent()

Get the public exponent of this key.

Specified by:

getPublicExponent in interface java.security.interfaces.RSAPublicKey

Returns:

The public exponent.

Throws:

java.lang.UnsupportedOperationException - If the value is not present or if the value is sensitive.

Postconditions:

(result <> null)

getModulus

public java.math.BigInteger getModulus()

Get the modulus of this key.

Specified by:

getModulus in interface java.security.interfaces.RSAKey

Returns:

The modulus.

Throws:

java.lang.UnsupportedOperationException - If the value is not present or if the value is sensitive.

Postconditions:

(result <> null)

getAlgorithm

public java.lang.String getAlgorithm()

Get the algorithm name.

Specified by:

getAlgorithm in interface java.security.Key

Overrides:

getAlgorithm in class IAIKPKCS11Key

Returns:

"RSA".

Postconditions:

(result <> null) and (result.equals("RSA"))

getKeyFactory

protected java.security.KeyFactory getKeyFactory()

Get a key factory that can encode this key according to X.509.

Overrides:

getKeyFactory in class IAIKPKCS11PublicKey

Returns:

A key factory which can encode this key or null if there is no such key factory available.
