Re: Verify signature (ECDSA_do_verify) using only x-coordinate in public key (EC_POINT)?

Hi, Thanks for your response. I'm sure that I only have the x-coordinate and when I reed up on ecc, it seems to be possible to verify the signature by only using this x-coordinate. Is there a way to do this with OpenSSL? Br, Jonas 2013/9/3 Matt Caswell fr...@baggins.org On 3 September 2013

32-bit Windows rebasing of OpenSSL FIPS library

I am having trouble loading the OpenSSL FIPS DLLs (2.0.5, using OpenSSL 1.0.1e) in my 32-bit Windows application. Most of the time I get a fingerprint does not match error from FIPS_mode_set but now and again, with no code changes, it succeeds. I have a feeling it has to do with rebasing and

Version difference

Hello, can someone please tell me the difference between OpenSSL x.x.x any date and OpenSSL x.x.x-fips any date is there a difference in functionality? is there a difference in legality? what does it tell to me, when openssl version shows fips, and what does it tell, when openssl version

PKCS7 signing

I'm working through the 'openssl smime -sign' example. 1 The '-in' parameter appears to be the message, not a hash of the message. Correct? 2 When I run the example, the PKCS7_Sign() call appears to add the entire message to the pkcs7 DER encoded file. Is this typical? Can I pass in
