+d2i_RSAPublicKey() and i2d_RSAPublicKey() decode and encode a PKCS#1 RSAPublicKey
+structure.
+
+d2i_RSA_PUKEY() and i2d_RSA_PUKEY() decode and encode an RSA public key using a
+SubjectPublicKeyInfo (certificate public key) structure.
+
+d2i_RSAPrivateKey(), i2d_RSAPrivateKey() decode and encode a PKCS#1 RSAPrivateKey
+structure.
+
+d2i_Netscape_RSA(), i2d_Netscape_RSA() decode and encode an RSA private key in
+NET format.
+
+The usage of all of these functions is similar to the d2i_X509() and
+i2d_X509() described in the L<d2i_X509(3)|d2i_X509(3)> manual page.
+
+=head1 NOTES
+
+The B<RSA> structure passed to the private key encoding functions should have
+all the PKCS#1 private key components present.
