\&\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.

.SH "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.
