   +----semper.certificate.CertificateContext
public class CertificateContext
extends Object
implements Serializable, Cloneable

Constructor Index

o CertificateContext()
Empty constructor - Serializable.
o CertificateContext(boolean, boolean)
Create a CertificateContext object.

Method Index

o clone()
Making clone public
o getEncCert()
Get the certificate to be used for encryption.
o getEncryptionKeyPair()
Method for getting the key pair for encryption.
o getName()
Retrieves the name in defined by the certificates in this context.
o getSignatureKeyPair()
Method for getting the key pair for signing.
o getSignCert()
Get the certificate to be used for signatures.
o getStatus()
Indicates the kind of certificates contained in the CertificateContext
o needEncryption()
Indicates if an encryption key is needed.
o needSigning()
Indicates if a signature key is needed.
o setEncCert(Certificate)
Set the certificate to be used for encryption.
o setSignCert(Certificate)
Set the certificate to be used for signatures.
o setStatus(ContextStatus)
Defines the kind of certificates contained in the CertificateContext
o updateCertificates(Certificate, Certificate)
Updates certificates in context.

Constructors

o CertificateContext 
 public CertificateContext()
Empty constructor - Serializable.

o CertificateContext 
 public CertificateContext(boolean needSign,
                           boolean needEnc)
Create a CertificateContext object. To be deprecated.

Parameters:
ba - is the name of the BA.
needSign - must be true if certificate on signature key is needed
needEnc - must be true if certificate on encryption key is needed

Methods

o setStatus 
 public void setStatus(ContextStatus status)
Defines the kind of certificates contained in the CertificateContext

Parameters:
Constant - defining the kind of certificates
o getStatus 
 public ContextStatus getStatus()
Indicates the kind of certificates contained in the CertificateContext

Returns:
Constant defining the kind of certificates
o needSigning 
 public boolean needSigning()
Indicates if a signature key is needed.

Returns:
true if this context specifies that signing is necessary
o needEncryption 
 public boolean needEncryption()
Indicates if an encryption key is needed.

Returns:
true if this context specifies that encryption is necessary
o setEncCert 
 public void setEncCert(Certificate cert) throws CertificateManException
Set the certificate to be used for encryption. Fails if the certificate does not certify a key to be used for encryption.

Parameters:
cert - is the certificate to be used for encryption
o setSignCert 
 public void setSignCert(Certificate cert) throws CertificateManException
Set the certificate to be used for signatures. Fails if the certificate does not certify a key to be used for signing.

Parameters:
cert - is the certificate to be used for signature
o getSignCert 
 public Certificate getSignCert()
Get the certificate to be used for signatures.

Returns:
the certificate to be used for signing
o getEncCert 
 public Certificate getEncCert()
Get the certificate to be used for encryption.

Returns:
the certificate to be used for encryption.
o updateCertificates 
 public void updateCertificates(Certificate signCert,
                                Certificate encCert) throws CertificateManException
Updates certificates in context.

Parameters:
signCert - is a certificate for signing;
encCert - is a certificate for encryption
o getName 
 public String getName() throws CertificateManException
Retrieves the name in defined by the certificates in this context. If the two certificates give different names an exception is thrown.

Parameters:
signCert - is a certificate for signing;
encCert - is a certificate for encryption
Throws: CertificateManException
if the a required certificate is null or the certificates don't ahve proepr scope
o clone 
 public synchronized Object clone()
Making clone public

Returns:
a clone of myself
Overrides:
clone in class Object
o getSignatureKeyPair 
 public CryptoKeyPair getSignatureKeyPair() throws CertificateManException
Method for getting the key pair for signing.

Returns:
a the key pair used for signing
Throws: CryptoManException
if the certificates contains no pointers to a key
o getEncryptionKeyPair 
 public CryptoKeyPair getEncryptionKeyPair() throws CertificateManException
Method for getting the key pair for encryption.

Returns:
a the key pair used for signing
Throws: CryptoManException
if the certificates contains no pointers to a key
