Usage:
    htpasswd [-cimBdpsDv] [-C cost] passwordfile username
    htpasswd -b[cmBdpsDv] [-C cost] passwordfile username password

    htpasswd -nb[mBdps] [-C cost] username password
 -c  Create a new file.
 -n  Dont update file; display results on stdout.

 -s  Force SHA encryption of the password (insecure).
 -p  Do not encrypt the password (plaintext, insecure).
