@cvar bad_record_mac: A TLS record failed to decrypt properly.
|
||
|
|
|
||
|
|
If this occurs during a shared-key or SRP handshake it most likely
|
||
|
|
indicates a bad password. It may also indicate an implementation
|
||
|
|
error, or some tampering with the data in transit.
|
||
|
|
|
||
|
|
This alert will be signalled by the server if the SRP password is bad. It
|
||
|
|
may also be signalled by the server if the SRP username is unknown to the
|
||
|
|
server, but it doesn't wish to reveal that fact.
|
||
|
|
|
||
|
|
This alert will be signalled by the client if the shared-key username is
|
||
|
|
bad.
|
||
|
|
|
||
|
|
@cvar handshake_failure: A problem occurred while handshaking.
|
||
|
|
|
||
|
|
This typically indicates a lack of common ciphersuites between client and
|
||
|
|
server, or some other disagreement (about SRP parameters or key sizes,
|
||
|
|
for example).
|
||
|
|
|
||
|
|
@cvar protocol_version: The other party's SSL/TLS version was unacceptable.
|
||
|
|
|
||
|
|
This indicates that the client and server couldn't agree on which version
|
||
|
|
of SSL or TLS to use.
|
||
|
|
|
||
|
|
@cvar user_canceled: The handshake is being cancelled for some reason.
