.SH VERSION

.SH METHODS
.IX Header "METHODS"
.SS \fBhash_len()\fP
.IX Subsection "hash_len()"
Returns the length (in bytes) of the hashes this algorithm generates.
.ie n .SS "generate($data, $key)"
.el .SS "generate($data, \f(CW$key\fP)"
.IX Subsection "generate($data, $key)"
Generate strong pseudorandom bits based on the \f(CW$data\fR and \f(CW$key\fR
.SS \fBto_algo_string()\fP
.IX Subsection "to_algo_string()"
Return a string representing any optional arguments this object was created
with, for use by Crypt::PBKDF2\*(Aqs \f(CW\*(C`generate\*(C'\fR and \f(CW\*(C`encode_string\*(C'\fR
methods. May return undef if no arguments are required, in which case none
will be serialized and \f(CW\*(C`from_algo_string\*(C'\fR won\*(Aqt be called on reading the
hash.
.SS from_algo_string($str)
.IX Subsection "from_algo_string($str)"
Given a string as produced by \f(CW\*(C`from_algo_string\*(C'\fR, return an instance of
this class with options corresponding to those in \f(CW$str\fR. If no options are
expected, it\*(Aqs permissible for this method to throw an exception.
