FINAL RESULTS:
data/libengine-gost-openssl1.1-1.1.0.3/gost.ec:4:13: [4] (crypto) crypt:
The crypt functions use a poor one-way hashing algorithm; since they only
accept passwords of 8 characters or fewer and only a two-byte salt, they
are excessively vulnerable to dictionary attacks given today's faster
computing equipment (CWE-327). Use a different algorithm, such as SHA-256,
with a larger, non-repeating salt.
