Constructor Detail

LibPQFactory

public LibPQFactory(Properties info)
             throws PSQLException

Parameters:

info - the connection parameters The following parameters are used: sslmode,sslcert,sslkey,sslrootcert,sslhostnameverifier,sslpasswordcallback,sslpassword

Throws:

PSQLException - if security error appears when initializing factory

Method Detail

throwKeyManagerException

public void throwKeyManagerException()
                              throws PSQLException

Propagates any exception from LazyKeyManager

Throws:

PSQLException - if there is an exception to propagate

verifyHostName

public static boolean verifyHostName(String hostname,
                     String pattern)

verify

public boolean verify(String hostname,
             SSLSession session)

Verifies the server certificate according to the libpq rules. The cn attribute of the certificate is matched against the hostname. If the cn attribute starts with an asterisk (*), it will be treated as a wildcard, and will match all characters except a dot (.). This means the certificate will not match subdomains. If the connection is made using an IP address instead of a hostname, the IP address will be matched (without doing any DNS lookups).

Specified by:

verify in interface HostnameVerifier

Parameters:

hostname - Hostname or IP address of the server.

session - The SSL session.

Returns:

true if the certificate belongs to the server, false otherwise.
