| /** |
| Public abstract interface for the X.509 Extension. |
| |
| This is used for X.509 v3 Certificates and CRL v2 (Certificate |
| Revocation Lists) for managing attributes assoicated with |
| Certificates, for managing the hierarchy of certificates, |
| and for managing the distribution of CRL. This extension |
| format is used to define private extensions. |
| |
| Each extensions for a certificate or CRL must be marked |
| either critical or non-critical. If the certificate/CRL |
| system encounters a critical extension not recognized then |
| it must reject the certificate. A non-critical extension |
| may be just ignored if not recognized. |
| |
| |
| The ASN.1 definition for this class is: |
| |
| Extensions ::= SEQUENCE SIZE (1..MAX) OF Extension |
| |
| Extension ::= SEQUENCE { |
| extnId OBJECT IDENTIFIER, |
| critical BOOLEAN DEFAULT FALSE, |
| extnValue OCTET STRING |
| -- contains a DER encoding of a value |
| -- of the type registered for use with |
| -- the extnId object identifier value |
| } |
