Please help me identify this Hash Code. '$1$DN$VSrllqW7nePlu.jmavF07.' I have never seen such hash code.
Looks like a SHA1 shrink .
SHA1 is cryptographically secure but weighs in uses 40 characters, which is pretty long if you're going to be passing the data around in a URL/cookie or something similar.
There are special functions that reduce SHA1 hash down to just 27 characters by using a base65 encoding that only uses URL-safe characters.
This looks exactly like your case.
Looks like the correct solution is
md5-crypt password hash:
$ openssl passwd -1 -salt DN 1q2w3e4r' --> '$1$DN$VSrllqW7nePlu.jmavF07.
