PassWordFromHash

PassWordFromHash is a lightweight software capable of generating a long, secure password that you can easily retrieve, by remembering three easy elements. The software relies on a checksum algorithm that combines the hashes from three instances: username, source and master password.

PassWordFromHash features a simple function, that of generating a strong, secure password that you can use to encrypt sensitive information. The algorithm used for creating the password involves combining the hashes of three instances: your username, the source website and the master password.

The application combines the words in the order mentioned above and calculates the RIPEMD-160 hash of that particular string. Next step involves converting the hash to a large number, between 1 and 2 to the power 160 minus 1. The number is then translated to 62-sing numeral system and each digit is represented as a character of 0 to 9 and letters, both upper or lower case.

The password generated by the software contains a maximum of 28 characters, both digits and letters, case sensitive. Thus the sequence of apparently random characters makes a difficult to remember password. This is why the software features the conversion algorithm, which returns the same result as long as the input is identical.

Even the slightest change results in a different password, because different character string yields a different hash. In other words, instead of remembering the long password, instead insert the exact username, source website and the master passphrase.

Unlike other password generators that create a random set of characters, PassWordFromHash can extract a strong passphrase from hashes. Thus, the sequence of digits and letters only seems to be random, but it actually it is the result of a multi-step process of calculations plus conversions.
