Sounds like you don't need the code from this thread at all, and I'm curious as to why you posted in this thread at all.

This thread serves our purpose. I started working on this with the intention to write something to both encrypt and decrypt the data. I chose to encrypt processed data and then write into the file. In reality we never have a plain-text file, I put that in the code here only for the purpose of testing. Instead, we have one processed data record from a webform submission (I skipped those details since the primary thread seemed to have a similar scenario, sans the webform maybe.). So the idea was to get each data record, encrypt it and then write into the file. The thought behind choosing this methodology was that the webform is actually hosted on another system (not part of our group) and this allowed to have plaintext data to be nowhere but in memory on the other system.

The purpose of the decryption section was that the encrypted file would be read in, decrypted and written into another black-box system (owned and operated by another group) that would store into their own proprietary database as they decrypt using our decryption section. In the example above, it's being stored into a file here to try to get it working first.

Now, the people encrypting the file can't use PERL and therefore all this goes out of the window. So far, they want to use just the BlowfishNET 2.1.2 library and class mentioned above. So, I am no longer concerned with the encryption part, only with decrypting it. However, I am confused as to how encryption is being performed using that class and therefore I queried you about the order to see if you think my understanding of the order of encryption is correct. We have been guided to the README docs and basically asked to figure it out from there. I hope I am explaining the situation correctly here, but I am not sure if they encrypt by making a call to the BlowfishSimple class everytime they process a record (one webform submission) or is it basically being called to encrypt a plaintext file as a whole. I am lost and therefore the post.

I'll put in a request for an encrypted message using BlowfishNET that I can post here and then put it here along with the key.

Thank you for your help.
