| 33 | + * Lists all the object identifiers of the X509 extensions of the PKIX profile. | |
| 34 | + * | |
| 35 | + * <p>Extensions are addiitonal attributes which can be inserted in a X509 | |
| 36 | + * v3 certificate. For example a "Driving License Certificate" could have | |
| 37 | + * the driving license number as a extension. | |
| 38 | + * | |
| 39 | + * <p>Extensions are represented as a sequence of the extension identifier | |
| 40 | + * (Object Identifier), a boolean flag stating whether the extension is to | |
| 41 | + * be treated as being critical and the extension value itself (this is again | |
| 42 | + * a DER encoding of the extension value). | |
