- 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 is replaced by Encryption.
The Encryption property allows you to manage the type of encryption used between Client computers and an HFSQL server. You can: - Find out the type of encryption used for an HFSQL Client/Server connection.
- Define the type of encryption used for the 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.
Remark: The connection can correspond to:
MyConnection is Connection // Describe the 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

<Type of encryption>: Constant Returns the type of encryption used for the connection: | | New in version 28hEncryptionAES128 | The connection between the server and the client computers is encrypted using a 128-bit AES encryption algorithm with the OFB mode of operation. | New in version 28hEncryptionAES192 | The connection between the server and the client computers is encrypted using a 192-bit AES encryption algorithm with the OFB mode of operation. | New in version 28hEncryptionAES256 | The connection between the server and the client computers is encrypted using a 256-bit AES encryption algorithm with the OFB mode of operation. | hEncryptionNO | No encryption is performed. | hEncryptionRC5_16 | The connection between the server and the client computers is encrypted using an optimized 16-round RC5 encryption algorithm (128 bits). | hEncryptionStandard | The connection between the server and the client computers is encrypted using an optimized 128-bit encryption algorithm |
<Connection used>: Connection name Name of the connection used. This name is defined:
