Enhanced simplified version after Spring encryption tool Security3.1, springsecurity3.1

Enhanced simplified version after Spring encryption tool Security3.1, springsecurity3.1
Enhanced versions increase the number of encrypted strings to 80 bits, and the hash values generated each time are different.

Output

Password rapido matched successfully: Success
