+                                                    # on standard output rather than updating a file

+:-) secure bcrypt
+<code>
+htpasswd -nBC 10 testuser
+#        -n        Show ouput on stdout
+#         -B       Use bcrypt encryption algorithm
+#          -C 10   Computing time used for the bcrypt algorithm (higher is more secure but slower, default: 5, valid: 4 to 17)
