CryptMethod (Property)

In french: Cryptage

Not available with these kinds of connection

..CryptMethod is used to manage the type of encryption for the communication established between the client computers and the HFSQL server. You can:

Find out the type of encryption used for a HFSQL Client/Server connection.
Define the type of encryption used for the HFSQL Client/Server connection. In this case, if the connection is currently opened, it will be closed then re-opened with the new parameters during a first access to a data file that is using this connection.

Note: The connection can correspond to:

a connection described in the data model editor,
a connection described by HConnect, HDescribeConnection or HOpenConnection.
a connection described by a Connection variable.

Example

MyConnection is Connection
// Describe the connection
MyConnection..User = "USER"
MyConnection..Password = "PASSWORD"
MyConnection..Server = "MYSERVER"
MyConnection..Database = "Database"
MyConnection..CryptMethod = hCryptRC5_16

MyConnection..ExtendedInfo = "Extended information"

HOpenConnection(MyConnection)

Syntax

Finding out the type of encryption for a HFSQL Client/Server connection Hide the details

<Type of encryption> = <Connection name>..CryptMethod

<Type of encryption>: Constant

Returns the type of encryption used for the connection:
hCryptNo No encryption is performed
hCryptRC5_16 The connection between the server and the client computers is encrypted according to an optimized encryption algorithm (RC5 16 rounds on 128 bits)
hCryptStandard The connection between the server and the client computers is encrypted according to an optimized encryption algorithm on 128 bits

<Connection name>: Character string (with or without quotes)

Name of connection used. This name was defined:
in the data model editor,
by HDescribeConnection or HOpenConnection,
by the Connection type.

Defining the type of encryption for a connection Hide the details

<Connection name>..CryptMethod = <Type of encryption>

<Connection name>: Character string (with or without quotes)

Name of connection used. This name was defined:
in the data model editor,
by HDescribeConnection or HOpenConnection,
by the Connection type.

<Type of encryption>: Constant

Defines the type of encryption used for the connection:
hCryptNo No encryption is performed
hCryptRC5_16 The connection between the server and the client computers is encrypted according to an optimized encryption algorithm (RC5 16 rounds on 128 bits).
hCryptStandard The connection between the server and the client computers is encrypted according to an optimized encryption algorithm on 128 bits.

Remarks

ExtendedInfo and connection

The information returned by ..CryptMethod is automatically updated when the information regarding the encryption of a HFSQL Client/Server connection is modified by ..ExtendedInfo (and conversely).

Therefore, the following code line:

MyConnection..CryptMethod = hCryptRC5_16

will modify the ENCRYPTION option in the string of extended information.

Similarly, the following code line:

MyConnection..ExtendedInfo = "CRYPT=RC5_16"

will modify ..CryptMethod.
