RFC4279 extends to common TLS scenario to one with a pre-shared-key (PSK). This
is rarely used, but if it is, and the key is known, it can be decrypted fairly
easy, since only the session-key generation has to be adopted. To quote from
the RFC, RFC4279 "specifies three sets of new ciphersuites for the Transport
Layer Security (TLS) protocol to support authentication based on pre-shared
keys (PSKs). These pre-shared keys are symmetric keys, shared in advance among
the communicating parties."
The patch adds an input field for an psk in hex format to the ssl protocol
options and applies this key when a psk ciphersuite is recognised.
