As per Javadoc call to System.Console() will return attached console to JVM if it has been started interactive command prompt or it will return. Password-based encryption generates a cryptographic key using a user password as a starting point. We irreversibly convert the password to a fixed-length hash code using a one-way hash function, adding a second random string as salt, to prevent hackers from performing dictionary attacks, where a list of common passwords are mapped to their hashed outputs -- if the hacker knows the hashing.

For this example, we will use the password strength indicator of Cpanel when creating passwords. The images below show the password strengths of each of the above-listed passwords.
