Providing a high security password from an initial character string of lowercase letter and numbers, and inclusion of one or more other characters

摘要

A technique supplies a high security password. The technique involves receiving, by processing circuitry, a series of randomly generated values from random number generator circuitry. The technique further involves deriving, by the processing circuitry, an initial character string from the series of randomly generated values, each character of the initial character string being an element of a first collection of characters which includes lowercase letters and numbers. The technique further involves providing, by the processing circuitry and as the high security password, a modified character string based on (i) the initial character string and (ii) inclusion of at least one element of a second collection of characters which is mutually exclusive of the first collection of characters.
