I'm working on a method to encapsulate complete data chunks as individual parts. One way to do this would be to use a pull parser to get one part at a time. Example:
<page> encrypted data here... </page>
In this text file example my encrypted data is htmlText where I deliberately remove line breaks, return numToChar(13) & numToChar(10) So later when a cross-platform file is decrypted "<p>" & return is used to replace "<p>"
One implementation could be to save each page's encrypted data in an array that is savable in a customProperty. The reason I mention all this is Blowfish takes about a half a second to build the encryption boxes that are used to encrypt and decrypt data. If the data is encrypted in smaller sized user chunks then a Transcript/Blowfish is not noticed much. It can slow things down when you attempt to encrypt an entire data source all at once.
Contact me off list if you are interested in getting Transcript/Blowfish.
