       i2d_RSAPrivateKey, d2i_RSA_PUBKEY, i2d_RSA_PUBKEY,

SYNOPSIS    [Toc]    [Back]

        #include <openssl/rsa.h>
        #include <openssl/x509.h>

        RSA * d2i_RSAPublicKey(RSA **a, unsigned char **pp,  long
length);

        int i2d_RSAPublicKey(RSA *a, unsigned char **pp);

        RSA  *  d2i_RSA_PUBKEY(RSA  **a, unsigned char **pp, long
length);

        int i2d_RSA_PUBKEY(RSA *a, unsigned char **pp);

        RSA * d2i_RSAPrivateKey(RSA **a, unsigned char **pp, long
length);

        int i2d_RSAPrivateKey(RSA *a, unsigned char **pp);

        int  i2d_Netscape_RSA(RSA  *a,  unsigned  char  **pp, int
(*cb)());

        RSA * d2i_Netscape_RSA(RSA **a, unsigned char **pp,  long
length, int (*cb)());

DESCRIPTION    [Toc]    [Back]

       d2i_RSAPublicKey() and i2d_RSAPublicKey() decode and
       encode a PKCS#1 RSAPublicKey structure.

       d2i_RSA_PUBKEY() and i2d_RSA_PUBKEY() 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 d2i_X509(3)
       manual page.

NOTES    [Toc]    [Back]

       The RSA structure passed to the private key encoding functions
 should have all the PKCS#1 private key components
       present.

       The data encoded by the private key functions is unencrypted
 and therefore offers no private key security.

       The NET format functions are present to provide compatibility
 with certain very old software. This format has
       some severe security weaknesses and should be avoided if
       possible.
