- 128-bit, 192-bit and 256-bit AES encryption with the OFB mode of operation
FicEncryption (Property) In french: CryptageFic
  Available only with these kinds of connection
 Warning
From version 28 (75), FicCryptMethod is kept for backward compatibility. This property is replaced by FicEncryption.
The FicEncryption property is used to set the encryption method of a data file. You can: - Get the encryption method of a data file (.FIC) (file defined in the data model editor or programmatically).
- Define the encryption method of a data file programmatically.
// Find out the encryption mode of the Customer data file
ResEncrypt = Customer.FicEncryption
Syntax
Finding out the encryption mode of a data file Hide the details
<Current encryption mode> = <Data file>.FicEncryption
<Current encryption mode>: Integer constant The encryption modes are:
| | | hEncryptionAES128 | 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). | | hEncryptionAES192 | Encryption is performed only if a password is set for the data file. In this case, the data file is encrypted using a 192-bit AES algorithm with Output feedback (OFB). | | hEncryptionAES256 | Encryption is performed only if a password is set for the data file. In this case, the data file is encrypted using a 256-bit AES algorithm with Output feedback (OFB). | | hEncryptionAuto | 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). | | hEncryptionNO | No encryption is performed on the data file. | | hEncryptionRC5_12 | The data file is encrypted according to an optimized encryption algorithm (RC5 12 rounds on 128 bits). | | hEncryptionRC5_16 | The data file is encrypted according to an optimized encryption algorithm (RC5 16 rounds on 128 bits). | | hEncryptionStandard | The data file is encrypted according to an optimized encryption algorithm on 128 bits. |
<Data file>: Character string Name of the data file used. This name was defined in the data model editor or with the File Description type.
Defining the encryption mode of a data file Hide the details
<Data file>.FicEncryption = <New encryption mode>
<Data file>: Character string Name of the data file used. This name was defined by the File Description type. <New encryption mode>: Integer constant The encryption modes are:
| | | hEncryptionAES128 | 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). | | hEncryptionAES192 | Encryption is performed only if a password is set for the data file. In this case, the data file is encrypted using a 192-bit AES algorithm with Output feedback (OFB). | | hEncryptionAES256 | Encryption is performed only if a password is set for the data file. In this case, the data file is encrypted using a 256-bit AES algorithm with Output feedback (OFB). | | hEncryptionAuto | 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). | | hEncryptionNO | No encryption is performed on the data file. | | hEncryptionRC5_12 | The data file is encrypted according to an optimized encryption algorithm (RC5 12 rounds on 128 bits). | | hEncryptionRC5_16 | The data file is encrypted according to an optimized encryption algorithm (RC5 16 rounds on 128 bits). | | hEncryptionStandard | The data file is encrypted according to an optimized encryption algorithm on 128 bits. |
Remarks 128-bit, 192-bit and 256-bit AES encryption with the 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 (MmoEncryption property) and indexes (NdxEncryption property).
- 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.
