I have a v13-based Mac application that’s been happily zipping files for an 
email attachment for years. Now, I’d like to add a password (preferably) 
zero-length to prevent a certain mail server from trying to read this file. The 
current code (that I didn’t write) and that I believe is creating the zipped 
file is:

$SourceFile:=Replace string($FilePath;":";"/")
$SourceFile:="/Volumes/"+$SourceFile
$SourceFile:=Substring($SourceFile;Position("/";$SourceFile);Length($SourceFile)-(Position("/";$SourceFile)-1))
$ZipFile:=$SourceFile
$ZipFile:=Substring($ZipFile;1;Length($ZipFile)-3)+"zip"
LAUNCH EXTERNAL PROCESS("ditto -c -k -X --norsrc "+Char(Double 
quote)+$SourceFile+Char(Double quote)+" "+Char(Double 
quote)+$ZipFile+Char(Double quote);$in;$out;$err)
$ZipFile:=Replace string($FilePath;".xls";".zip")

How do you typically handle creating zipped files, intended to be emailed, on 
Mac-based system?  How would you add the encryption or password protection to 
such a file?

Thanks,

Robert
