143 RSA_new, RSA_free \- allocate and free RSA objects
147 .IX Header "SYNOPSIS"
149 \& #include <openssl/rsa.h>
151 \& RSA * RSA_new(void);
153 \& void RSA_free(RSA *rsa);
156 .IX Header "DESCRIPTION"
157 \&\fIRSA_new()\fR allocates and initializes an \fB\s-1RSA\s0\fR structure. It is equivalent to
158 calling RSA_new_method(\s-1NULL\s0).
160 \&\fIRSA_free()\fR frees the \fB\s-1RSA\s0\fR structure and its components. The key is
161 erased before the memory is returned to the system.
163 .IX Header "RETURN VALUES"
164 If the allocation fails, \fIRSA_new()\fR returns \fB\s-1NULL\s0\fR and sets an error
165 code that can be obtained by \fIERR_get_error\fR\|(3). Otherwise it returns
166 a pointer to the newly allocated structure.
168 \&\fIRSA_free()\fR returns no value.
170 .IX Header "SEE ALSO"
171 \&\fIERR_get_error\fR\|(3), \fIopenssl_rsa\fR\|(3),

176 \&\fIRSA_new()\fR and \fIRSA_free()\fR are available in all versions of SSLeay and OpenSSL.
