Jon:

You said, "... which was also encrypted with QC3DECDT." But, you would need to use QC3ENCDT to "Encrypt." =-O

Also, you did not state which encryption algorithm you are using (selected via parameters to QC3ENCDT and QC3DECDT). This really matters, because some encryption algorithms are "block ciphers" that work on chunks of 64 bits at a time, or 16 bytes at a time, etc., while other algorithms are "stream" ciphers that can accept a variable number of bytes.

Are you setting up the "algorithm context" first, by calling the QC3CRTAX API? Which algorithm are you specifying?

Hope that helps,

I am trying to use QC3DECDT to decrypt an encrypted field which was also encrypted with QC3DECDT. Sometimes (6 out of 2381 records ) I am getting CPF9DD6 which is "Length of area provided for output data is too small.". I have my clear data output length set to 50 which should be plenty big, as the first one I am getting an error on is only 16 characters encrypted. Can anyone help?

Thanks, Jon
