/** |
|
38 |
* This class represents the Inhibit Any-Policy Extension. |
|
39 |
* |
|
40 |
* <p>The inhibit any-policy extension can be used in certificates issued |
|
41 |
* to CAs. The inhibit any-policy indicates that the special any-policy |
|
42 |
* OID, with the value {2 5 29 32 0}, is not considered an explicit |
|
43 |
* match for other certificate policies. The value indicates the number |
|
44 |
* of additional certificates that may appear in the path before any- |
|
45 |
* policy is no longer permitted. For example, a value of one indicates |
|
46 |
* that any-policy may be processed in certificates issued by the sub- |
|
47 |
* ject of this certificate, but not in additional certificates in the |
|
48 |
* path. |
|
49 |
* <p> |
|
50 |
* This extension MUST be critical. |
|
51 |
* <p> |
|
52 |
* The ASN.1 syntax for this extension is: |
|
53 |
* <code><pre> |
|
54 |
* id-ce-inhibitAnyPolicy OBJECT IDENTIFIER ::= { id-ce 54 } |
|
55 |
* |
|
56 |
* InhibitAnyPolicy ::= SkipCerts |
|
57 |
* |
|
58 |
* SkipCerts ::= INTEGER (0..MAX) |
|
