This is similar to a sha1 hash (length 40). To decipher it is the same as to pick it up randomly, it is almost impossible))
Just hope that the user has set a simple password and get the sha1 hash of all simple passwords and compare it with the original one.
I tried a couple of online decryption services, but they don't know anything about this hash)
Not allowed.
This is not encryption, it is a hash of the built-in PASSWORD function in MySQL.
They say that in versions 5.1, 5.5 and 5.6, SHA1 is applied twice to the password string inside this function, but this detail is not available in the documentation. Here, you can check it out:
SELECT
SHA1(UNHEX(SHA1('password'))),
PASSWORD('password');
The documentation, however, still says that for any other purpose, except for authentication in MySQL, this function should not be used.
