.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fIRSA_new()\fR allocates and initializes an \fB\s-1RSA\s0\fR structure. It is equivalent to
calling RSA_new_method(\s-1NULL\s0).
.PP
\&\fIRSA_free()\fR frees the \fB\s-1RSA\s0\fR structure and its components. The key is
erased before the memory is returned to the system.
If \fBrsa\fR is \s-1NULL\s0 nothing is done.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
If the allocation fails, \fIRSA_new()\fR returns \fB\s-1NULL\s0\fR and sets an error
code that can be obtained by \fIERR_get_error\fR\|(3). Otherwise it returns
a pointer to the newly allocated structure.
.PP
\&\fIRSA_free()\fR returns no value.
