 The \fIparams\fR argument is an \fIargv\fR-like null-terminated vector of type
 \fBchar *\fR. The first element of \fIparams\fR represents the mechanism token
 name from \fBcrypt.conf\fR(4). The remaining elements of \fIparams\fR represent
 strings of the form <\fBparameter\fR>[=<\fBvalue\fR>] to allow passing in
-additional information from the \fBcrypt.conf\fR entry, such as specifing
