I wrote a process to encrypt data as part of our FTP Client product because I needed to store the password associated with a remote system. I was in the process of changing the code to allow me to create an MD5 checksum for data comparison when I found a couple of new API’s. After a bit of investigation and some challenges with documentation I managed to get the API’s to work and now have a process where I can check the data at record level between two files on separate systems using the MD5 checksum created using the API. I will be retro fitting the use of the APi’s into my FTP Client as they are a lot easier to support than the code I had to write.. Check out the API QC3CALHA if you are interested. There are a lot more security API’s which will make security programming easier on the i5!
