Please help me identify this Hash Code. '$1$DN$VSrllqW7nePlu.jmavF07.' I have never seen such hash code.

    It's a md5-crypt password hash: $ openssl passwd -1 -salt DN 1q2w3e4r --> $1$DN$VSrllqW7nePlu.jmavF07. – Arminius Feb 10 '17 at 7:35

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.

Thanks Arminius.

    On the contrary, this looks infinitely more likely to be a Linux password hash. – Stephen Touset Feb 10 '17 at 7:05
  • The beginning looks like that, but I don't think those would use SHA-1 shrinks. the linux MD5 hash should be $1+32 characters (34 chars in total). – Overmind Feb 10 '17 at 7:31

    @Overmind I commented the "solution" below the question. You might want to include that in your answer. – Arminius Feb 10 '17 at 7:38
