CryptoInformation callback
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(void *Sftp,char *Protocol,char *RemoteName,char *SCcipher,char *CScipher,char *Keys,int *Accept) 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.Platforms
