The algorithm is chosen using the -t alternative and critical size using the -b alternative. The next commands illustrate:
SSH keys are two long strings of people which can be used to authenticate the id of a person requesting use of a distant server. The user generates these keys on their own regional Personal computer using an SSH utility.
