If I understood task correctly, here is answer:

Raw password and iv before hashing (sha512) - https://pastebin.com/A6JLrELy

Also attached final passwords to use with AES

pass.bin

iv.bin

All right @SHADOW_UA 

please can you evaluate the difficulty of getting the password ?

There's a way to find out which functions are being called without devirtualizing Eazfuscator.NET. When you find that out, you can just start original (protected) crackme in debugger and place bp on certain methods to grab its parameters values. Why you should debug original crackme instead of dumped one? That's because some strings are protected with internal Enigma Protector features and they are getting loaded only if this protector is still applied. I am evaluating this crackme as 4/10 difficulty.
