java - SQL Password Decrypt -

-

i having trouble finding out how decrypt sql passwords. many questions similar, none same. sql syntax:

insert `a2166327_db`.`users` ( `id` , `username` , `password` , `bio` ) values ( '2', 'waffles', password( 'waffles' ) , 'waffles' );

i entry:
|2|waffles|*a734e3e66d51b5043a297ec66ee24d3bc26ae328|waffles|

how decrypt *a734e3e66d51b5043a297ec66ee24d3bc26ae328 "waffles?"
can in java?

  • this example: hash('admin') return 'd033e22ae348aeb5660fc2140aec35850c4da997'

  • but can't decrypt result !!! why encryption existing, secure data. hash functions yoused in 1 way

  • but can compare data in backend programming.

  • if(hash('admin') == 'sql_password'){...}

  • and example of java hash class. java hash class encrypt secret password
