This shouldn't be necessary becasuse the underlying method gets notified through EVP_PKEY_CTX_set_signature_md() which it can then check and take appropriate action. If the method wants to change the MD it can set the EVP_PKEY_FLAG_SIGCTX_CUSTOM flag and then use whatever EVP_MD is appropriate instead of the passed one. Steve. -- Dr Stephen N. Henson.
