This is an interface of abstract methods for managing a variety of identity certificates. An identity certificate is a guarantee by a principal that a public key is that of another principal. (A principal represents an entity such as an individual user, a group, or a corporation.)
In particular, this interface is intended to be a common abstraction for constructs that have different formats but important common uses. For example, different types of certificates, such as X.509 certificates and PGP certificates, share general certificate functionality (the need to encode and decode certificates) and some types of information, such as a public key, the principal whose key it is, and the guarantor guaranteeing that the public key is that of the specified principal. So an implementation of X.509 certificates and an implementation of PGP certificates can both utilize the Certificate interface, even though their formats and additional types and amounts of information stored are different.
Important: This interface is useful for cataloging and grouping objects sharing certain common uses. It does not have any semantics of its own. In particular, a Certificate object does not make any statement as to the validity of the binding. It is the duty of the application implementing this interface to verify the certificate and satisfy itself of its validity.
Certificate
Method Summary | |
void |
decode(InputStream stream)
Deprecated. Decodes a certificate from an input stream. |
void |
encode(OutputStream stream)
Deprecated. Encodes the certificate to an output stream in a format that can be decoded by the decode method. |
String |
getFormat()
Deprecated. Returns the name of the coding format. |
Principal |
getGuarantor()
Deprecated. Returns the guarantor of the certificate, that is, the principal guaranteeing that the public key associated with this certificate is that of the principal associated with this certificate. |
Principal |
getPrincipal()
Deprecated. Returns the principal of the principal-key pair being guaranteed by the guarantor. |
PublicKey |
getPublicKey()
Deprecated. Returns the key of the principal-key pair being guaranteed by the guarantor. |
String |
toString(boolean detailed)
Deprecated. Returns a string that represents the contents of the certificate. |
