How to find out the hashing method from previously known strings?

Question

Programming

Good afternoon, there are some source files written in C#
They use the (unknown to me) method EncryptedAction("....");
A cipher is placed inside the method, using simple methods I managed to guess some primitive strings.
Actually a question! Are there services or software for selecting (search) an encryption method based on previously known and recognized cipher strings?
Something like ....
1. Enter the encrypted text:
2. Enter the exact decryption:
3. Press the "FIND" button to start searching for the encryption method in the database!
Z.Y. Of course, I exaggerate this, but to make it clearer what I really want!

Answer 1

In one literature, I briefly saw that there the hash was considered as
XOR EAX, EBX
Exclusive for machine words of the same length, the length can be different 8,16,32,64, ...
If you come up with some more sophisticated algorithm, then no one in life won't guess.
You can write a prog enumeration but the effect is unlikely.
If you suddenly used base64 ...
Then you can understand this by programming through the browser.
As you can imagine, it's also 50/50.
