Only two column out of 8 has been encrypted using AES and being collectively sent as csv file. Is it still not possible to decrypt?

So you are saying you have a text file, which has several data columns divided by commas, and some of those data columns have had some algorithm applied to them. If so then you need access to that algorithm and the solving code, and then you would apply it to the data once you have read the data into SAS. There is no un-encode coded data function as far as I am aware. I would ask why you have chosen to go this route in the first place of encoding some data. It would be far simpler, and more secure, to protect the whole file - most apps can do it, e.g. zip - and send the whole file like that via secure FTP or Web Portal.

Only if the encrypted value was converted to readable code, eg with base64 encoding.
Because encryption would get you values that sooner or later will contain delimiters and therefore break your file structure. Raw encrypted values and separators don't work together.
And from the documentation I get it that only complete files, not separate columns, can be encrypted.
