| 42 | * A <code>CertSelector</code> that selects <code>X509Certificates</code> that |
| 43 | * match all specified criteria. This class is particularly useful when |
| 44 | * selecting certificates from a <code>CertStore</code> to build a |
| 45 | * PKIX-compliant certification path. |
| 46 | * <p> |
| 47 | * When first constructed, an <code>X509CertSelector</code> has no criteria |
| 48 | * enabled and each of the <code>get</code> methods return a default value |
| 49 | * (<code>null</code>, or <code>-1</code> for the {@link #getBasicConstraints |
| 50 | * getBasicConstraints} method). Therefore, the {@link #match match} |
| 51 | * method would return <code>true</code> for any <code>X509Certificate</code>. |
| 52 | * Typically, several criteria are enabled (by calling |
| 53 | * {@link #setIssuer setIssuer} or |
| 54 | * {@link #setKeyUsage setKeyUsage}, for instance) and then the |
| 55 | * <code>X509CertSelector</code> is passed to |
| 56 | * {@link CertStore#getCertificates CertStore.getCertificates} or some similar |
| 57 | * method. |
| 58 | * <p> |
| 59 | * Several criteria can be enabled (by calling {@link #setIssuer setIssuer} |
| 60 | * and {@link #setSerialNumber setSerialNumber}, |
| 61 | * for example) such that the <code>match</code> method |
| 62 | * usually uniquely matches a single <code>X509Certificate</code>. We say |
| 63 | * usually, since it is possible for two issuing CAs to have the same |
| 64 | * distinguished name and each issue a certificate with the same serial |
| 65 | * number. Other unique combinations include the issuer, subject, |
| 66 | * subjectKeyIdentifier and/or the subjectPublicKey criteria. |
| 67 | * <p> |
| 68 | * Please refer to <a href="http://www.ietf.org/rfc/rfc3280.txt">RFC 3280: |
| 69 | * Internet X.509 Public Key Infrastructure Certificate and CRL Profile</a> for |
| 70 | * definitions of the X.509 certificate extensions mentioned below. |
| 71 | * <p> |
| 72 | * <b>Concurrent Access</b> |
| 73 | * <p> |
| 74 | * Unless otherwise specified, the methods defined in this class are not |
| 75 | * thread-safe. Multiple threads that need to access a single |
| 76 | * object concurrently should synchronize amongst themselves and |
| 77 | * provide the necessary locking. Multiple threads each manipulating |
| 78 | * separate objects need not synchronize. |
