WebDescription. The EVP digest routines are a high level interface to message digests. EVP_MD_CTX_init () initializes digest context ctx . EVP_MD_CTX_create () allocates, initializes and returns a digest context. EVP_DigestInit_ex () sets up digest context ctx to use a digest type from ENGINE impl. ctx must be initialized before calling this ...
