Use pre-shared key cipher suites
SSL-enabled classes in SecureBlackbox support Pre-shared key (PSK) cipher suites as defined by RFC 4279.
PSK cipher suites are different from regular SSL/TLS cipher suites already because they utilize shared-key approach to security, while SSL was originally based on other principles.
To make use of PSK cipher suites, you need to take the following steps:
Remember, that PSK is a very recent addition to TLS, and it's not supported by most TLS clients and servers.
