Claim:
1. A method of supplying a high security password, the method comprising: receiving, by processing circuitry, a series of randomly generated values from random number generator circuitry; 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; and 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; wherein the method further comprises storing at least one of the modified character string and an encryption key derived from the modified character string together with sensitive key manager configuration information in a lockbox cryptographic repository; and wherein storing includes encrypting a set of data storage system encryption keys using the encryption key derived from the modified character string, the encrypted set of data storage system encryption keys forming at least part of the sensitive key manager configuration information.
