- 128-bit, 192-bit and 256-bit AES encryption with the Output Feedback (OFB) mode
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 has been replaced with FicEncryption.
The FicEncryption property sets the encryption method of a data file. You can: - Know how to encrypt a data file (.FIC) (data file defined in the data model editor or programmatically defined).
- Define the encryption method of a data file programmatically.
ResEncrypt = Customer.FicEncryption
Syntax
Getting the encryption method of a data file Hide the details
<Current encryption method> = <Data file>.FicEncryption
<Current encryption method>: Integer constant The encryption methods 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 the Output Feedback (OFB) mode. | | 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 the Output Feedback (OFB) mode. | | 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 the Output Feedback (OFB) mode. | | hEncryptionAuto | Encryption is performed only if a password is set for the data file. In this case, the data file is encrypted using an optimized 16-round RC5 algorithm with a 128-bit key. | | hEncryptionNO | No encryption is performed on the data file. | | hEncryptionRC5_12 | The data file is encrypted using an optimized 12-round RC5 algorithm with a 128-bit key. | | hEncryptionRC5_16 | The data file is encrypted using an optimized 16-round RC5 algorithm with a 128-bit key. | | hEncryptionStandard | The data file is encrypted using an optimized 128-bit algorithm. |
<Data file>: Character string Name of the data file used. This name is defined in the data model editor or with the File Description type.
Defining the encryption method of a data file Hide the details
<Data file>.FicEncryption = <New encryption method>
<Data file>: Character string Name of the data file used. This name is defined with the File Description type. <New encryption method>: Integer constant The encryption methods 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 the Output Feedback (OFB) mode. | | 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 the Output Feedback (OFB) mode. | | 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 the Output Feedback (OFB) mode. | | hEncryptionAuto | Encryption is performed only if a password is set for the data file. In this case, the data file is encrypted using an optimized 16-round RC5 algorithm with a 128-bit key. | | hEncryptionNO | No encryption is performed on the data file. | | hEncryptionRC5_12 | The data file is encrypted using an optimized 12-round RC5 algorithm with a 128-bit key. | | hEncryptionRC5_16 | The data file is encrypted using an optimized 16-round RC5 algorithm with a 128-bit key. | | hEncryptionStandard | The data file is encrypted using an optimized 128-bit algorithm. |
Remarks 128-bit, 192-bit and 256-bit AES encryption with the Output Feedback (OFB) mode - If the data file is encrypted using the AES algorithm, you need to use the same method to encrypt memos (MmoEncryption property) and indexes (NdxEncryption property).
- If there is encryption that uses the AES algorithm, the option "Enable enhanced security " is automatically applied. In this mode, a password must be set for the data file. This password will be requested each time the data file is automatically modified.
