[openssl-users] Valid strings to be passed to EVP_get_digestbyname()

2016-02-18 Thread Nayna Jain
Hi, I am trying to use EVP APIs for generating sha256 hashes. I think of the step is to pass the digest name to EVP_get_digestbyname() and get the EVP_MD* structure However, I am not able to find the valid string to be passed for SHA256 hash algorithm.. I tried passing "sha256", &q

There are a few places these things are specified -- in the names given to the OID arcs, which means looking in SSL, TLS, CMS, S/MIME, etc. OpenSSL has a pretty complete list of those. Another source is in the URI's for things like XMLDSig and XMLEncryption. Your approach of having an 'alias t

I'm trying to develop an application with OpenSSL that needs to verify a variety of digital signatures from different places. Currently I use EVP_get_digestbyname to get an EVP_MD handle identifying the algorithm used, and this works well for things that originally came from OpenSSL, but
