I used 'N', which produces the same encoding on all systems. Why did you change it?

On one server I couldn't use 'N' or 'Q'. It gave me an invalid-type error. I can understand 'Q' not working, but I am not sure why 'N' did not work. It worked everywhere else.

I am now trying to decrypt a file that is encrypted using the BlowfishNET 2.1.2 library from http://www.hotpixel.net/software.html using the BlowfishSimple class. (The people encrypting the file don't use PERL, but I do.) The README for the above-mentioned says:

"For efficiency the given string will be UTF-8 encoded and padded to the next 8byte block border. The CBC IV plus the encrypted data will then be BASE64 encoded and returned as the final encryption result."

Based upon my understanding so-far I am trying to use the following approach to decrypt the data without success:

Decode using MIME::Base64::decode. I am unsure here as to whether I have to decode the entire file or 57 bytes at a time. Would you have any suggestions?
Read 8 bytes at a time and decode the string using utf8::decode($string). In your read_uint32, I'm changing return (unpack('N', read_bytes($fh, 4))); to return utf8::decode(read_bytes($fh, 4));

Thank you very much for your help and comments.
