Usage: htpasswd [-cimBdpsDv] [-C cost] passwordfile username htpasswd -b[cmBdpsDv] [-C cost] passwordfile username password htpasswd -n[imBdps] [-C cost] username htpasswd -nb[mBdps] [-C cost] username password -c Create a new file. -n Don't update file; display results on stdout. -b Use the password from the command line rather than prompting for it. -i Read password from stdin without verification (for script usage). -m Force MD5 encryption of the password (default). -B Force bcrypt encryption of the password (very secure). -C Set the computing time used for the bcrypt algorithm (higher is more secure but slower, default: 5, valid: 4 to 31). -d Force CRYPT encryption of the password (8 chars max, insecure). -s Force SHA encryption of the password (insecure). -p Do not encrypt the password (plaintext, insecure). -D Delete the specified user. -v Verify password for the specified user. On other systems than Windows and NetWare the '-p' flag will probably not work. The SHA algorithm does not use a salt and is less secure than the MD5 algorithm.
