Topic: ctaocrypt for basic RSA+AES c lib support
Hello, I'm trying to compile the latest stable version of ctaocrypt in VisualStudio 2013. I've tried using the provided project file, and I've tried creating my own cleaner project for it but I hit the same issue.
All I want is to get the most basic Rsa and AES calls in ctaocrypt, no ssl, no tls, no certs or anything like that, just:
RsaPublicKeyDecode RsaSSL_Verify AesSetKey AesCbcEncrypt AesCbcDecrypt RsaPublicEncrypt InitRng RsaPrivateKeyDecode RsaPrivateDecrypt RNG_GenerateBlock
The issue I am finding is that:
a) the project provided as-is does not compile (pretty sure even on older VS versions) since it fails to include memory.c which is required for user-specified alloc functions etc.
b) I can never seem to compile (and link) succesfully without the two following errors:
2>ctaocrypt.lib(asn.obj) : error LNK2019: unresolved external symbol _GetCA referenced in function _ParseCertRelative 2>ctaocrypt.lib(asn.obj) : error LNK2019: unresolved external symbol _GetCAByName referenced in function _ParseCertRelative
I've tried compiling with NO_CERTS, but this causes other dependencies between Rsa/Sha256/Asn. I can't find the right combination of flags to remove these. I can get the GetCAByName to go away by using NO_SKID, but not the GetCA one.
This used to work several versions ago (maybe 1-2 years ago, not sure the exact version), but it looks like asn.c was refactored and broke this.
If it's not a supported "mode" (bare-bones ctaocrypt) anymore, are there any recommendations on a possible alternative. I really just wanted a portable, lightweight RSA+AES implementation in C.
