Documentation

Class AttributeCertificateImpl is an implementation class for AkentiCertificate.

The format for an attribute certificate is: 

AttributeCertificateImpl { 
type                      useCondCertificate
id                        Certificate unique id 
Issuer                    Issuer and signer of certificate 
version                   Certificate format version 
NotBefore                 cert is not valid before
NotAfter                  cert is not valid after 
signatureAlg              signature algorithm
Attribute                 attribute name  
Value                     attribute value 
Extensions                vector of additonal constraints on this attribute 
Signature                 SignatureInfo 
}

These certificates are mainly used to authorize a subject for a certain pair in order to satisfy the constraints in a UseCondCertificate . Akenti Extensions are provided in case, there is a necessity to specify more specific attributes or constraints.

Certificates are generated through AkentiCertificateFactory. There are different generators that are used in order to generate appropriate certificates. There are two ways in which an Attribute Certificate can be generated First way,
AttributeCertificate cert = AkentiCertificateFactory.getInstance("AttributeCert"); cert.readObject(AkentiInputStream& stream);
Second way,
AkentiCertGenerator attrCertGen = AkentiCertificateFactory.getInstance("AttributeCertGen"); attrCertGen.setGuarantor(..); attrCertGen.setAttribute(..); .......... AttributeCertificateImpl attrcert = attrCertGen.generate(); // In order to write the object into the output stream or encode the object // do the following attrcert.writeObject(AkentiOutputStream& stream);

AttributeCertGenerator()
Constructs this object

~AttributeCertGenerator()

void setAttribute(const string& attribute)
Sets the attributes for a particular certificate. An example of an attribute could be "group".
Parameters:
attribute - the attribute of the Akenti Certificate

void setValue(const string& value)
Sets the value for the attribute.
Parameters:
value - the value associated with the attribute

void setPrincipal(const AkentiPrincipal& principal)
Sets the principal for the Akenti Certificate.
Parameters:
principal - the principal of the Akenti Certificate

void addAkentiExtension(const AkentiExtension& extensions)
Sets the Akenti Extensions to this certificate
Parameters:
extensions - the extensions for this certificate
