Why does EVP_get_digestbyname("md4") return non-NULL if the legacy
provider isn't loaded? Similarly, why does it return non-NULL for "md5"
after doing EVP_set_default_properties(NULL, "fips=yes")? This seems
unintuitive. Legacy code that does not know about EVP_MD_fetch() checks
the return valu
Hi,
there is an error in your code - see my comment below.

Hi team,
I find a segment fault in BIO_read() on openssl 3.0 about calculate digest with
BIO using md4 algorithm.
This is my test code, put it in a.c, build & run, it will crash.
If don't load legacy provider:
1. Set dgst = "md4", EVP_get_digestbyname(dgst) won't return NULL, but a
non-NULL
