+SHA1 (RFC 3174), MD5 (RFC 1321) and RIPEMD160 (RFC 2286) legacy, weak hash functions.
+Don't use them in a new protocol. What "weak" means:
+
+- Collisions can be made with 2^18 effort in MD5, 2^60 in SHA1, 2^80 in RIPEMD160.
+- No practical pre-image attacks (only theoretical, 2^123.4)
+- HMAC seems kinda ok: https://datatracker.ietf.org/doc/html/rfc6151
