163 \&\fId2i_RSA_PUBKEY()\fR and \fIi2d_RSA_PUBKEY()\fR decode and encode an \s-1RSA\s0 public key using
164 a SubjectPublicKeyInfo (certificate public key) structure.
166 \&\fId2i_RSAPrivateKey()\fR, \fIi2d_RSAPrivateKey()\fR decode and encode a PKCS#1 RSAPrivateKey
169 \&\fId2i_Netscape_RSA()\fR, \fIi2d_Netscape_RSA()\fR decode and encode an \s-1RSA\s0 private key in
172 The usage of all of these functions is similar to the \fId2i_X509()\fR and
173 \&\fIi2d_X509()\fR described in the \fId2i_X509\fR\|(3) manual page.
176 The \fB\s-1RSA\s0\fR structure passed to the private key encoding functions should have
177 all the PKCS#1 private key components present.
179 The data encoded by the private key functions is unencrypted and therefore
180 offers no private key security.
182 The \s-1NET\s0 format functions are present to provide compatibility with certain very
183 old software. This format has some severe security weaknesses and should be
