Question

I have been given a problem to decrypt this text:

3e47b75000b0924b6c9ba5759a7cf15d

which is supposedly an encrypted password stored in a database.

In the hint it says:”Find out what is the most common encryption used for storing passwords online. Use that to decrypt the password.”

I tried some algorithm like Base64 etc but failed to decipher it.

Any suggestion or the solution to this.

Answer 1

It’s the password ‘nothing’ hashed using MD5. I found the answer using an online MD5 plaintext/hash database.

Verfification on the command line:

$ echo -n nothing | md5sum.exe
