The ASN.1 definition of Basic Constraints Extension is:
id-ce-basicConstraints OBJECT IDENTIFIER ::= { id-ce 19 }
BasicConstraints ::= SEQUENCE {
cA BOOLEAN DEFAULT FALSE,
pathLenConstraint INTEGER (0..MAX) OPTIONAL
}
(as specified in RFC 3280)
the value of pathLenConstraint field if extension presents,and Integer.MAX_VALUE if does not. |
| valueOfCertificateIssuerExtension | | public X500Principal valueOfCertificateIssuerExtension() throws IOException(Code) | | Returns the value of Certificate Issuer Extension (OID = 2.5.29.29).
It is a CRL entry extension and contains the GeneralNames describing
the issuer of revoked certificate. Its ASN.1 notation is as follows:
id-ce-certificateIssuer OBJECT IDENTIFIER ::= { id-ce 29 }
certificateIssuer ::= GeneralNames
(as specified in RFC 3280)
the value of Certificate Issuer Extension |
| valueOfExtendedKeyUsage | | public List valueOfExtendedKeyUsage() throws IOException(Code) | | Returns the value of Extended Key Usage extension (OID == 2.5.29.37).
The ASN.1 definition of Extended Key Usage Extension is:
id-ce-extKeyUsage OBJECT IDENTIFIER ::= { id-ce 37 }
ExtKeyUsageSyntax ::= SEQUENCE SIZE (1..MAX) OF KeyPurposeId
KeyPurposeId ::= OBJECT IDENTIFIER
(as specified in RFC 3280)
the list with string representations of KeyPurposeId's OIDsand null
throws:
IOException - if extension was incorrectly encoded. |
| valueOfIssuerAlternativeName | | public List valueOfIssuerAlternativeName() throws IOException(Code) | | Returns the value of Issuer Alternative Name Extension (OID = 2.5.29.18).
The ASN.1 definition for Issuer Alternative Name is:
id-ce-issuerAltName OBJECT IDENTIFIER ::= { id-ce 18 }
IssuerAltName ::= GeneralNames
