byte[] getExtensionValue(String oid)
oid
String.
The oid
string is
represented by a set of nonnegative whole numbers separated
by periods.
For example:
OID (Object Identifier) | Extension Name |
---|---|
2.5.29.14 | SubjectKeyIdentifier |
2.5.29.15 | KeyUsage |
2.5.29.16 | PrivateKeyUsage |
2.5.29.17 | SubjectAlternativeName |
2.5.29.18 | IssuerAlternativeName |
2.5.29.19 | BasicConstraints |
2.5.29.30 | NameConstraints |
2.5.29.33 | PolicyMappings |
2.5.29.35 | AuthorityKeyIdentifier |
2.5.29.36 | PolicyConstraints |
oid
- the Object Identifier value for the extension.
