- * SRP client-side negotiation
- *
- * This code negotiates the client side of an SRP exchange.
- * "t_clientopen" accepts a username, and N, g, and s parameters,
- * which are usually sent by the server in the first round.
- * The client should then call...
- * "t_clientgenexp" will generate a random 256-bit exponent and
- * raise g to that power, returning the result. This result
- * should be sent to the server as w(p).
- * "t_clientpasswd" accepts the user's password, which should be
- * entered locally and updates the client's state.
- * "t_clientgetkey" accepts the exponential y(p), which should
- * be sent by the server in the next round and computes the
- * 256-bit session key. This data should be saved before the
- * session is closed.
- * "t_clientresponse" computes the session key proof as SHA(y(p), K).
- * "t_clientclose" closes the session and frees its memory.
- *
- * Note that authentication is not performed per se; it is up
- * to either/both sides of the protocol to now verify securely
- * that their session keys agree in order to establish authenticity.
- * One possible way is through "oracle hashing"; one side sends
- * r, the other replies with H(r,K), where H() is a hash function.
- *
- * t_clientresponse and t_clientverify now implement a version of
- * the session-key verification described above.
