Description
-
Called before wodSFTP establishes an encrypted connection
with the server.
Syntax
-
void (*CryptoInformation)(void *Sftp,
char *Protocol, char *RemoteName, char
*SCcipher, char *CScipher, char *Keys,
int *Accept);
The CryptoInformation Event syntax has these parts:
| void
*Sftp |
Handle of the created Sftp
instance. |
| char
*Protocol |
Holds the selected
protocol (SSH2 is the only possibility in SFTP
protocol). |
| char
*RemoteName |
Holds the remote
identification string. |
| char
*SCcipher |
Holds the selected server to
client encryption algorithm. |
| char
*CScipher |
Holds the selected client to
server encryption algorithm. |
| char
*Keys |
Holds the key exchange
algorithm selected. |
| int
*Accept |
When set to 0
(null, false), wodSFTP aborts the connection. |
Remarks
-
The CryptoInformation callback is called after the first
crypto negotiation has taken place, but before any
sensitive information is sent to the server (such as username
or password). This callback provides you with information
about the selected encryption protocols and the remote server
type.
At this point you can decide whether to continue
with the connection or to abort it (by setting the
Accept parameter to False)
in which case wodSFTP will drop the connection.
NOTE: this callback is called only if
you have created an instance of the SftpEventsStruct structure, and set its CryptoInformation member to the
function implementing it.
