Hi I am on Linux, and would like to generate a key with "unique 40" fingerprint. eg 1: Starts with ABCD XXXX ... XXXX eg 2: Starts with AXXX XXXX ... XXXA ends with A eg 3: XXXX ... XXXX without any '0' character at all How would I go about writing such a script? Don't mind running for months to get these sets. Regards
