.SH NAME
RSA_new, RSA_free \- allocate and free RSA objects
.SH SYNOPSIS
.IX Header "SYNOPSIS"
.Vb 1
\& #include <openssl/rsa.h>
\&
\& RSA * RSA_new(void);
\&
\& void RSA_free(RSA *rsa);
.Ve
.SH DESCRIPTION
.IX Header "DESCRIPTION"
\&\fBRSA_new()\fR allocates and initializes an \fBRSA\fR structure. It is equivalent to
calling RSA_new_method(NULL).
.PP
\&\fBRSA_free()\fR frees the \fBRSA\fR structure and its components. The key is
erased before the memory is returned to the system.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
If the allocation fails, \fBRSA_new()\fR returns \fBNULL\fR and sets an error
code that can be obtained by \fBERR_get_error\fR\|(3). Otherwise it returns
a pointer to the newly allocated structure.
.PP
\&\fBRSA_free()\fR returns no value.

.SH HISTORY
.IX Header "HISTORY"
\&\fBRSA_new()\fR and \fBRSA_free()\fR are available in all versions of SSLeay and OpenSSL.
