-.BI \-s " secret"
-The secret to hash.  If not provided, the user will be prompted
-for the secret to hash.
+.B \-u
+Generate RFC 2307 userPassword values (the default).  Future
+versions of this program may generate alternative syntaxes
+by default.  This option is provided for forward compatibility.

 .TP

-.BI \-h " scheme"
-The hash scheme to use.  RFC2307 schemes supported include
-.IR {CRYPT} ,
-.IR {MD5} ,
-.IR {SMD5} ,
-.IR {SSHA} ", and"
-.IR {SHA} .
+.BI \-s \ secret
+The secret to hash.
+If this,

+and
+.B \-T
+are absent, the user will be prompted for the secret to hash.
+.BR \-s ,
+.B \-g
+and

+are mutually exclusive flags.

+.BI \-g
+Generate the secret.

+are absent, the user will be prompted for the secret to hash.
+.BR \-s ,
+.B \-g
+and
+.B \-T
+are mutually exclusive flags.
+If this is present,
+.I {CLEARTEXT}
+is used as scheme.
+.B \-g
+and
+.B \-h
+are mutually exclusive flags.
+.TP
+.BI \-T \ "file"
+Hash the contents of the file.
+If this,
+.B \-g
+and
+.B \-s
+are absent, the user will be prompted for the secret to hash.
+.BR \-s ,
+.B \-g
+and
+.B \-T
+and mutually exclusive flags.
+.TP
+.BI \-h \ "scheme"
+If \fB\-h\fP is specified, one of the following RFC 2307 schemes may
+be specified:
+.BR {CRYPT} ,
+.BR {MD5} ,
+.BR {SMD5} ,
+.BR {SSHA} ", and"
+.BR {SHA} .

 The default is 
 The default is 

-.IR {SSHA} .
-.LP
-If \-a is specified, the following authPassword schemes
-may be specified:
-.IR MD5 ,
-.IR SHA1 ", and"
-.IR X-CRYPT .
+.BR {SSHA} .
+
+Note that scheme names may need to be protected, due to
+.B {
+and
+.BR } ,
+from expansion by the user's command interpreter.
+
+.B {SHA}
+and
+.B {SSHA}
+use the SHA-1 algorithm (FIPS 160-1), the latter with a seed.
+
+.B {MD5}
+and
+.B {SMD5}
+use the MD5 algorithm (RFC 1321), the latter with a seed.
+
+.B {CRYPT}
+uses the
+.BR crypt (3).
+
+.B {CLEARTEXT}
+indicates that the new password should be added to userPassword as
+clear text.
+Unless
+.I {CLEARTEXT}
+is used, this flag is incompatible with option
+.BR \-g .
+.TP
+.BI \-c \ crypt-salt-format
+Specify the format of the salt passed to
+.BR crypt (3)
+when generating {CRYPT} passwords.  
+This string needs to be in
+.BR sprintf (3)
+format and may include one (and only one)
+.B %s
+conversion.
+This conversion will be substituted with a string of random
+characters from [A\-Za\-z0\-9./].  For example,
+.RB ' %.2s '
+provides a two character salt and
+.RB ' $1$%.8s '
+tells some
+versions of
+.BR crypt (3)
+to use an MD5 algorithm and provides
+8 random characters of salt.

 The default is
 The default is

-.IR SHA1 .
+.RB ' %s ' ,
+which provides 31 characters of salt.
+.TP
+.BI \-n
+Omit the trailing newline; useful to pipe the credentials
+into a command.
+.TP
+.BI \-o \ option\fR[ = value\fR]
+Specify an
+.I option
+with a(n optional)
+.IR value .
+Possible generic options/values are:
+.LP
+.nf
+              module\-path=<pathspec> (see `\fBmodulepath\fP' in slapd.conf(5))
+              module\-load=<filename> (see `\fBmoduleload\fP' in slapd.conf(5))
+
+.in
+You can load a dynamically loadable password hash module by
+using this option.

 .SH LIMITATIONS
 .SH LIMITATIONS

-The practice storing hashed passwords in userPassword
-violates Standard Track schema and may hinder
-interoperability.  authPassword is not yet widely supported.
+The practice of storing hashed passwords in userPassword violates
+Standard Track (RFC 4519) schema specifications and may hinder
+interoperability.  A new attribute type, authPassword, to hold
+hashed passwords has been defined (RFC 3112), but is not yet
+implemented in
+.BR slapd (8).
+.LP
+It should also be noted that the behavior of
+.BR crypt (3)
+is platform specific.

 Use of hashed passwords does not protect passwords during
 protocol transfer.  TLS or other eavesdropping protections
