Method Detail

getBasicConstraints

public int getBasicConstraints()

Gets the certificate constraints path length from the critical BasicConstraints extension, (OID = 2.5.29.19).

The basic constraints extension identifies whether the subject of the certificate is a Certificate Authority (CA) and how deep a certification path may exist through that CA. The pathLenConstraint field (see below) is meaningful only if cA is set to TRUE. In this case, it gives the maximum number of CA certificates that may follow this certificate in a certification path. A value of zero indicates that only an end-entity certificate may follow in the path.

The ASN.1 definition for this is:

 BasicConstraints ::= SEQUENCE {
     cA                  BOOLEAN DEFAULT FALSE,
     pathLenConstraint   INTEGER (0..MAX) OPTIONAL }
 

Returns:

the value of pathLenConstraint if the BasicConstraints extension is present in the certificate and the subject of the certificate is a CA, otherwise -1. If the subject of the certificate is a CA and pathLenConstraint does not appear, Integer.MAX_VALUE is returned to indicate that there is no limit to the allowed length of the certification path.
