A bit of Math. You need to find the correct password. There is only one password. The difficulty may be easy or medium.

4aca7f6c on 9:23 PM 05/27/2019: Cute little math problem! Thanks! SHA1(password) = 7c9072c5d04b607523834d174e51366cc65cd666
x0r19x91 on 3:55 PM 05/28/2019: That bug causes it to have multiple solutions. But it won't be hard if you can guess the charset :-)
4aca7f6c on 9:45 PM 05/28/2019: @x0r19x91: I think the non-uniqueness adds to the fun, even if you consider it a bug --- it makes you have to think a little more about how to come up with a solution, since there are choices to be made #4x10m_0f_ch01c3. But yes, I'm aware my solution wasn't the intended one. I'm assuming the one you had in mind satisfies SHA1(password) = c2008e29ab0ea2383a1afb5010309d4097f8f7c3 ?
x0r19x91 on 1:01 AM 05/29/2019: That's the intended password ! Well done @4aca7f6c
x0r19x91 on 1:36 AM 11/09/2019: Excellent Solution @4aca7f6c :-)
