Hi!

I have no idea is this is related to Clarion but if you want to read a BINARY file, you have to use the DOS driver to read the contents of the file. I have no idea of the layout of CER/KEY files though.

Hi!

So, do you know the data structure of these files? How are they delimited i.e. what are the column and row separators?

If they have column & row delimiters/separators you can use the BASIC driver OR if they are plain ASCII files you can use the ASCII driver OR the DOS driver should be good to read anything.

Shankar,

These are digital certificate files. SSL/RSA stuff.

Lokper, you'll have to resort to some library, like OpenSSL. You can always buy some black boxed DLL and call its functions.

As a start, I suggest you get a look at Putty source, which is also open. C stuff, though.
