178\&\fId2i_RSAPublicKey()\fR and \fIi2d_RSAPublicKey()\fR decode and encode a PKCS#1 RSAPublicKey
179structure.
180.PP
181\&\fId2i_RSA_PUKEY()\fR and \fIi2d_RSA_PUKEY()\fR decode and encode an \s-1RSA\s0 public key using a
182SubjectPublicKeyInfo (certificate public key) structure.
183.PP
184\&\fId2i_RSAPrivateKey()\fR, \fIi2d_RSAPrivateKey()\fR decode and encode a PKCS#1 RSAPrivateKey
185structure.
186.PP
187\&\fId2i_Netscape_RSA()\fR, \fIi2d_Netscape_RSA()\fR decode and encode an \s-1RSA\s0 private key in
188\&\s-1NET\s0 format.
189.PP
190The usage of all of these functions is similar to the \fId2i_X509()\fR and
191\&\fIi2d_X509()\fR described in the d2i_X509(3) manual page.
192.SH "NOTES"
193.IX Header "NOTES"
194The \fB\s-1RSA\s0\fR structure passed to the private key encoding functions should have
195all the PKCS#1 private key components present.
196.PP
197The data encoded by the private key functions is unencrypted and therefore
198offers no private key security.
199.PP
200The \s-1NET\s0 format functions are present to provide compatibility with certain very
201old software. This format has some severe security weaknesses and should be
202avoided if possible.
