Originated in
Troi Encryptor Plug-in 1.2
Compatibility
FileMaker Pro 16 to FileMaker Pro 2023
Considerations
NOTE 1: short strings (less than 20 characters) of text might be longer after compression.
NOTE 2: the compression result can contain all ASCII codes (0-255). See “Encr_EncodeSafeAscii” for conversion to safe ASCII codes.
Example
Set Field [ result ; Encr_Compress ( "-Unused" ; "123456789 123456789 123456789" ) ]will result in the compressed string: “xú3426153∑∞T0ƒd Wÿ”
Example 2
In a document database you have defined a text field named “letterContents” which contains the main part of a letter. Then you can define a calculation field:
LetterCompressCalc calculation = Encr_Compress ( "-Unused" ; LetterContents )this field will contain the compressed version of the field.
