KEYS: X.509: Parse Basic Constraints for CA
Parse the X.509 Basic Constraints. The basic constraints extension
identifies whether the subject of the certificate is a CA.
BasicConstraints ::= SEQUENCE {
cA BOOLEAN DEFAULT FALSE,
pathLenConstraint INTEGER (0..MAX) OPTIONAL }
If the CA is true, store it in the public_key. This will be used
in a follow on patch that requires knowing if the public key is a CA.
