Encr_EncryptNewDES |
Encrypts text using a DES algorithm and the current crypt key. Specify a key first with the function Encr_SetCryptKey.
Syntax
Encr_EncryptNewDES ( switches ; text )
Parameters
| switches | reserved for future use, leave empty or set to "-Unused" |
| text | the text to encrypt |
Returned Result
Data type returned
Text
Result
the encrypted text
Originated in
Troi Encryptor Plug-in 1.2
Compatibility
FileMaker Pro 16 to FileMaker Pro 2023
Considerations
– The NewDES algorithm is not considered safe anymore.
– AES is a more secure algorithm than NewDES. See the function Encr_EncryptAES.
– Be sure to remember the key (case sensitive!): without it you can not retrieve the original text.
Use Encr_Code to encrypt without the need for a script.
– The result field should be a text field. If you encrypt into a date or number field it won’t work as FileMaker wants to interpret is as a (date) number.
Compatibility with Troi Coding Plug-in:
For backward compatibility, passwords are still Mac ASCII encoded except for chars not in the Mac ASCII set, these chars are now UTF8 encoded before the key is derived. For example:
“japan_显示” becomes “japan_0xE698BEE7A4BA” as password
“españa” becomes “españa” as password
Text is converted to the FileMaker Pro 6 character set. For other characters the UNICODE value is converted to a numeral reference. This ensures that fields with data from older FileMaker 6 databases will have the same encryption. The numeral references look like: À which is the Greek small letter pi.
Example
Set Field [ gErrorCode ; Encr_SetCryptKey ( "-Unused" ; "mySecret" ) ]
If [ gErrorCode = 0 ]
Set Field [ result ; Encr_EncryptNewDES ( "-Unused" ; "Hello World" ) ]
Set Field [ gErrorCode ; Encr_SetCryptKey ( "-Unused" ; "different Key" ) ]
End Ifgives this result: “l’ùé—JtO<=! Û¡\}0Óÿ„]˘¿Cºdè≈ˇ”
Example 2
In a database you have defined a text field named “patientData” which contains illness data. Then define a calculation field:
encryptedDataCalc calculation Unstored = Encr_EncryptNewDES ( "-Unused" ; patientData )this field will contain the encrypted text.
TIP Use the Encr_EncodeSafeAscii function for sending data safely over internet.
