.SH "Detailed Description"
.PP
See the \fBRSA - public-key cryptography\fP for description and examples.
.SH "Function Documentation"
.PP
.SS "void RSA_free (RSA * rsa)"
.PP
Free an allocation RSA object.
.PP
\fBParameters:\fP
.RS 4
\fIrsa\fP the RSA object to free.
.RE
.PP
.SS "void* RSA_get_app_data (const RSA * rsa)"
.PP
Get the application data for the RSA object.
.PP
\fBParameters:\fP
.RS 4
\fIrsa\fP the rsa object to get the parameter for
.RE
.PP
\fBReturns:\fP
.RS 4
the data object
.RE
.PP
.SS "const RSA_METHOD* RSA_get_method (const RSA * rsa)"
.PP
Return the RSA_METHOD used for this RSA object.
.PP
\fBParameters:\fP
.RS 4
\fIrsa\fP the object to get the method from.
.RE
.PP
\fBReturns:\fP
.RS 4
the method used for this RSA object.
.RE
.PP
.SS "RSA* RSA_new (void)"
.PP
Same as \fBRSA_new_method()\fP using NULL as engine.
.PP
\fBReturns:\fP
.RS 4
a newly allocated RSA object. Free with \fBRSA_free()\fP.
.RE
.PP
.SS "RSA* RSA_new_method (ENGINE * engine)"
.PP
Allocate a new RSA object using the engine, if NULL is specified as the engine, use the default RSA engine as returned by ENGINE_get_default_RSA().
.PP
\fBParameters:\fP
.RS 4
\fIengine\fP Specific what ENGINE RSA provider should be used.
.RE
.PP
\fBReturns:\fP
.RS 4
a newly allocated RSA object. Free with \fBRSA_free()\fP.
.RE
.PP
.SS "int RSA_set_app_data (RSA * rsa, void * arg)"
.PP
Set the application data for the RSA object.
.PP
\fBParameters:\fP
.RS 4
\fIrsa\fP the rsa object to set the parameter for
.br
\fIarg\fP the data object to store
.RE
.PP
\fBReturns:\fP
.RS 4
1 on success.
.RE
.PP
.SS "int RSA_set_method (RSA * rsa, const RSA_METHOD * method)"
.PP
Set a new method for the RSA keypair.
.PP
\fBParameters:\fP
.RS 4
\fIrsa\fP rsa parameter.
.br
\fImethod\fP the new method for the RSA parameter.
.RE
.PP
\fBReturns:\fP
.RS 4
1 on success.
.RE
.PP
.SS "int RSA_up_ref (RSA * rsa)"
.PP
Add an extra reference to the RSA object. The object should be free with \fBRSA_free()\fP to drop the reference.
.PP
\fBParameters:\fP
.RS 4
\fIrsa\fP the object to add reference counting too.
.RE
.PP
\fBReturns:\fP
.RS 4
the current reference count, can't safely be used except for debug printing.
