- ExtendedInfo property and connection
Encryption (Property) In french: Cryptage
Not available with these kinds of connection
Warning
From version 28 (75), CryptMethod is kept for backward compatibility. This property has been replaced with Encryption.
The Encryption property allows you to manage the type of encryption used between Client computers and an HFSQL server. You can: - Get the type of encryption used for an HFSQL Client/Server connection.
- Define the type of encryption used for an HFSQL Client/Server connection. In this case, if the connection is currently open, it will be closed and opened again with the new parameters when first accessing a data file that uses this connection.
Note: The connection can correspond:
MyConnection is Connection
MyConnection.User = "USER"
MyConnection.Password = "PASSWORD"
MyConnection.Server = "MYSERVER"
MyConnection.Database = "Database"
MyConnection.Encryption = hEncryptionRC5_16
MyConnection.Provider = hAccessHFClientServer
MyConnection.Access = hOReadWrite
MyConnection.ExtendedInfo = "Extended information"
HOpenConnection(MyConnection)
Syntax
Getting the type of encryption for an HFSQL Client/Server connection Hide the details
<Type of encryption> = <Connection used>.Encryption
<Type of encryption>: Constant Returns the type of encryption for the connection:
| | hEncryptionAES128 | The connection between the server and the client computers is encrypted using a 128-bit AES algorithm with the Output Feedback (OFB) mode. | hEncryptionAES192 | The connection between the server and the client computers is encrypted using a 192-bit AES algorithm with the Output Feedback (OFB) mode. | hEncryptionAES256 | The connection between the server and the client computers is encrypted using a 256-bit AES algorithm with the Output Feedback (OFB) mode. | hEncryptionNO | No encryption is performed. | hEncryptionRC5_16 | The connection between the server and the client computers is encrypted using an optimized 16-round RC5 algorithm with a 128-bit key. | hEncryptionStandard | The connection between the server and the client computers is encrypted using an optimized 128-bit algorithm. |
<Connection used>: Connection name Name of the connection used. This name is defined:
