Encoding Arrays with File Paths

[Bob Sneidar]

The structure looks like the following:

Sly File Agent API
   Structure of payload sent

      [0] 
         [profile] <selected location profile>
      [n] 
         [data] <encrypted binary data of file>
         [datemodified] <file system date modified>
         [extpath] <file path suffix unique to each file>
         [filecategory] <used by sql files database when data is returned>
         [fileid] <used by sql files database when data is returned>
         [filename] <name of file to be saved to disk. Also used by sql files database when data is returned>
         [filepath] <root path to save file to. extpath should be appended to this>
         [operation] <savefile, retrievefile, movefile, deletefile>
         [saveaction] <new, newversion, overwrite unique to each file>
         [version] <new version number also used by sql files database when data is returned>
      [n+1]…

The problem is definitely the binary data stored in the [n] [“data”] key. If I immediately decrypt the data in the key on the MacOS the data is correct. But when I decrypt the exact same data on the Windows OS I get a bad decrypt error. 

So to be perfectly clear, I create the above array, I iterate through each key from 1 to n, encrypting and overwriting the information in the [“data”] key. I then arrayEncode the entire array, then base64encode everythign before transmitting it over the wire. 

I reverse the process on the receiving side. It seems to work if I send non-binary data in the [“data”] key but if the data is binary, it fails. I do not think arrayEncode / decode likes to work with binary data.
