I downloaded a source code study of thinkphp5.3 from the Internet. Because there is no installation file, it can only be installed through database import. After importing the database and configuring the database connection file, find

in the admin table in phpmydmin.

admin:admin

password:12eefdf664f0e07e65a2c35e01e98d29

I decrypted the password and got the clear text password: o8889t

When logging in to the source code backend, it keeps prompting for an incorrect password or account number. Then I changed the password in the admin table to e10adc3949ba59abbe56e057f20f883e. The plain text is: 123456

When I log in again, I still find that the account or password is wrong. I want to know what encryption method the backend password is. Or how can I successfully log in to the background? Three files are listed, please give me some advice, thank you very much.
