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:
  • 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.
Example
// Get the encryption method of the Customer data file
ResEncrypt = Customer.FicEncryption
Syntax

Getting the encryption method of a data file Hide the details

<Current encryption mode> = <Data file>.FicEncryption
<Current encryption mode>: Integer constant
The encryption methods are:
hEncryptionAES128Encryption 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.
hEncryptionAES192Encryption 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.
hEncryptionAES256Encryption 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.
hEncryptionAutoEncryption 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 encryption algorithm with a 128-bit key.
hEncryptionNONo encryption is performed on the data file.
hEncryptionRC5_12The data file is encrypted using an optimized 12-round RC5 encryption algorithm with a 128-bit key.
hEncryptionRC5_16The data file is encrypted using an optimized 16-round RC5 encryption algorithm with a 128-bit key.
hEncryptionStandardThe data file is encrypted using an optimized 128-bit encryption algorithm.
<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 method 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 methods are:
hEncryptionAES128Encryption 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.
hEncryptionAES192Encryption 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.
hEncryptionAES256Encryption 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.
hEncryptionAutoEncryption 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 encryption algorithm with a 128-bit key.
hEncryptionNONo encryption is performed on the data file.
hEncryptionRC5_12The data file is encrypted using an optimized 12-round RC5 encryption algorithm with a 128-bit key.
hEncryptionRC5_16The data file is encrypted using an optimized 16-round RC5 encryption algorithm with a 128-bit key.
hEncryptionStandardThe data file is encrypted using an optimized 128-bit encryption 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 indices (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 each time the data file is automatically modified.
Minimum version required
  • Version 9
