Reference the non-"legacy" provider names directly from EVP_md5(3) &c. Earlier today, it took me five manuals! to find what on earth the "Performance"/"EVP_MD_fetch(3)" crosslinks actually mean: EVP_sha1(3) crypto(7) EVP_MD_fetch(3) (but not there! don't read that!) OSSL_PROVIDER-default(7) EVP_MD-SHA1(7) If, instead, EVP_sha1(3) referenced EVP_MD-SHA1(7) at /all/, which it should do, since it's supposed to be what you're replacing it with, but it doesn't actually say that, maybe people would use it. I know I didn't because it's basically just deadass buried As found by git grep -l 'and should consider using' Reviewed-by: Tomas Mraz <tomas@openssl.org> Reviewed-by: Matt Caswell <matt@openssl.org> (Merged from https://github.com/openssl/openssl/pull/22420)
