Archived Forum PostQuestion:
The CSR created by using CkCSR is invalidate to apply for CA's certificate.
I've tried Comodo, RapidSSL, StartSSL and got the same results due to invalidate signature.
I alse copy the CSR sample post on https://example-code.com/cpp/csr_generate_key_and_signing_request.asp
There is a same error occured: invalidate signature.
Please let me know what operating system, and if Windows, which version of VC++ you're using. I'll create a pre-release of v9.5.0.66 for you to test. This may be a problem that was already fixed..
Windows 10, VS2013(VC12),
Thanks
Please give this new build a try:

Hi Chilkat, I've tried just now. The result is "Signature Not Valid"
Maybe you can use this online tool to check. https://certlogik.com/decoder/
I found the problem and fixed it. It's very strange because this was working for various customers. I noticed that it was generating a signature using the little-endian byte ordering, which makes no sense because everything would normally be big-endian except historically Microsoft's Crypto API (not w.r.t. to CSR's, but with RSA in general..)
The fix was to just flip a switch from true to false within the code..
I'll rebuild, re-upload, and post the download links again when ready..
This new build should fix it:
