FicCryptMethod (Property)

In french: CryptageFic

Available only with these kinds of connection

..FicCryptMethod is used to configure the encryption mode of the data file. You can:

Find out the encryption mode of a data file (.FIC) (file defined in the data model editor of by programming).
Define the encryption mode of a data file during its description by programming.

ResEncrypt = Customer..FicCryptMethod

Syntax

Finding out the encryption mode of a data file Hide the details

<Current encryption mode> = <Data file>..FicCryptMethod

<Current encryption mode>: Integer constant

The encryption modes are:
Versions 24 and later
hCryptAES128
New in version 24
hCryptAES128
hCryptAES128 Encryption is performed only if a password is set for the data file. In this case, the data file is encrypted using a 128-bit AES algorithm with Output feedback (OFB).
Versions 19 and later
hCryptAuto
New in version 19
hCryptAuto
hCryptAuto Encryption is performed only if a password is set for the data file. In this case, the data file is encrypted according to an optimized encryption algorithm (RC5 16 rounds on 128 bits).
hCryptNo No encryption is performed on the data file.
hCryptRC5_12 The data file is encrypted according to an optimized encryption algorithm (RC5 12 rounds on 128 bits).
hCryptRC5_16 The data file is encrypted according to an optimized encryption algorithm (RC5 16 rounds on 128 bits).
hCryptStandard The data file is encrypted according to an optimized encryption algorithm on 128 bits.

<Data file>: Character string (with or without quotes)

Name of data file used. This name was defined in the data model editor or by the File description type.

Remarks

Versions 24 and later

128-bit AES encryption with OFB mode of operation

If the data file is encrypted using the AES algorithm, it is necessary to use the same method to encrypt the memos (..MmoCryptMethod) and indexes (..NdxCryptMethod).
If there is encryption that uses the AES algorithm, the option "Enable a high-security level " is automatically applied. In this mode, a password must be set for the data file. This password will be requested at each automatic modification of the data file.
