GnuPG is a freely available, widely used (at least in open software communities) encryption/digital signature software, and I believe it is secure enough for most applications. If you can convert those files into PDF, I think you can put signature on those files via Adobe Acrobat. An obvious benefit of this solution is that the signature validation mechanism is integrated into the Acrobat Reader, and readers of the documents don't have to run another software to validate the signature. I have no experience with Acrobat, but I guess it is secure enough and not difficult to use.
