/**
|
|
* <p>
|
|
* Abstract class for X.509 certificates. This provides a standard
|
|
* way to access all the attributes of an X.509 certificate.
|
|
* <p>
|
|
* In June of 1996, the basic X.509 v3 format was completed by
|
|
* ISO/IEC and ANSI X9, which is described below in ASN.1:
|
|
* <pre>
|
|
* Certificate ::= SEQUENCE {
|
|
* tbsCertificate TBSCertificate,
|
|
* signatureAlgorithm AlgorithmIdentifier,
|
|
* signature BIT STRING }
|
|
* </pre>
|
|
* <p>
|
|
* These certificates are widely used to support authentication and
|
|
* other functionality in Internet security systems. Common applications
|
|
* include Privacy Enhanced Mail (PEM), Transport Layer Security (SSL),
|
|
* code signing for trusted software distribution, and Secure Electronic
|
|
* Transactions (SET).
|
|
* <p>
|
|
* These certificates are managed and vouched for by <em>Certificate
|
|
* Authorities</em> (CAs). CAs are services which create certificates by
|
|
* placing data in the X.509 standard format and then digitally signing
|
|
* that data. CAs act as trusted third parties, making introductions
|
|
* between principals who have no direct knowledge of each other.
|
|
* CA certificates are either signed by themselves, or by some other
|
|
* CA such as a "root" CA.
|
|
* <p>
|
|
* More information can be found in
|
|
* <a href="http://www.ietf.org/rfc/rfc3280.txt">RFC 3280: Internet X.509
|
|
* Public Key Infrastructure Certificate and CRL Profile</a>.
|
|
* <p>
|
|
* The ASN.1 definition of {@code tbsCertificate} is:
|
|
* <pre>
|
|
* TBSCertificate ::= SEQUENCE {
|
|
* version [0] EXPLICIT Version DEFAULT v1,
|
|
* serialNumber CertificateSerialNumber,
|
|
* signature AlgorithmIdentifier,
|
|
* issuer Name,
|
|
* validity Validity,
|
|
* subject Name,
|
|
* subjectPublicKeyInfo SubjectPublicKeyInfo,
|
|
* issuerUniqueID [1] IMPLICIT UniqueIdentifier OPTIONAL,
|
|
* -- If present, version must be v2 or v3
|
|
* subjectUniqueID [2] IMPLICIT UniqueIdentifier OPTIONAL,
|
|
* -- If present, version must be v2 or v3
|
|
* extensions [3] EXPLICIT Extensions OPTIONAL
|
|
* -- If present, version must be v3
|
|
* }
|
|
* </pre>
|
|
* <p>
|
|
* Certificates are instantiated using a certificate factory. The following is
|
|
* an example of how to instantiate an X.509 certificate:
|
|
* <pre>
|
|
* try (InputStream inStream = new FileInputStream("fileName-of-cert")) {
|
|
* CertificateFactory cf = CertificateFactory.getInstance("X.509");
|
|
* X509Certificate cert = (X509Certificate)cf.generateCertificate(inStream);
|
|
* }
|
|
* </pre>
