PgDAC

TSSLMode Enumeration

This option determines whether or with what priority an SSL connection will be negotiated with the server.

Unit

PgClasses

Syntax

TSSLMode = (smDisable, smRequire, smPrefer, smAllow, smVerifyCA, smVerifyFull);

Values

Value Meaning
smAllow Negotiates trying first a non-SSL connection, then if that fails, tries an SSL connection.
smDisable Only an unencrypted SSL connection will be attempted.
smPrefer Negotiates trying first an SSL connection, then if that fails, tries a regular non-SSL connection.
smRequire Tries only an SSL connection.
smVerifyCA Verifies server identity by validating the server certificate chain up to the root certificate installed on the client machine.
smVerifyFull Verifies server identity by validating the server certificate chain up to the root certificate installed on the client machine and validates that the server hostname matches the server certificate.

Remarks

The default value is smDisable.

If PostgreSQL is compiled without SSL support, using option smRequire will cause an error, while options smAllow and smPrefer will be accepted, but PgDAC will not in fact attempt an SSL connection.
