I'm trying to convert my root certificate to Pem files using C unix. In my current code I'm using the openssl function
const EVP_MD *digest=EVP_sha1(); to make the digest as SHA1, but now I want to modify the code to support sha256 and sha512. >From the current openssl.h I found that X509->signature gives Signature Algorithm what my root certificate is holding. But is there a way to find what is the Signature Hash Algorithm that my root certificate is holding? Found a similar one in C#: How to retrieve the Signature hash algorithm friendly name using c# cryptography? But I need a similar one in C. Also is there any ppt which talks about the unix openssl.h in detail? -- Sent from: http://openssl.6102.n7.nabble.com/OpenSSL-Dev-f29372.html -- openssl-dev mailing list To unsubscribe: https://mta.openssl.org/mailman/listinfo/openssl-dev
