D2I_PRIVATEKEY(3)		    OpenSSL		     D2I_PRIVATEKEY(3)

NAME
       d2i_PrivateKey, d2i_PublicKey, d2i_AutoPrivateKey, i2d_PrivateKey,
       i2d_PublicKey, d2i_PrivateKey_bio, d2i_PrivateKey_fp - decode and
       encode functions	for reading and	saving EVP_PKEY	structures

SYNOPSIS
	#include <openssl/evp.h>

	EVP_PKEY *d2i_PrivateKey(int type, EVP_PKEY **a, const unsigned	char **pp,
				 long length);
	EVP_PKEY *d2i_PublicKey(int type, EVP_PKEY **a,	const unsigned char **pp,
				long length);
	EVP_PKEY *d2i_AutoPrivateKey(EVP_PKEY **a, const unsigned char **pp,
				     long length);
	int i2d_PrivateKey(EVP_PKEY *a,	unsigned char **pp);
	int i2d_PublicKey(EVP_PKEY *a, unsigned	char **pp);

	EVP_PKEY *d2i_PrivateKey_bio(BIO *bp, EVP_PKEY **a);
	EVP_PKEY *d2i_PrivateKey_fp(FILE *fp, EVP_PKEY **a)

DESCRIPTION
       d2i_PrivateKey()	decodes	a private key using algorithm type. It
       attempts	to use any key specific	format or PKCS#8 unencrypted
       PrivateKeyInfo format. The type parameter should	be a public key
       algorithm constant such as EVP_PKEY_RSA.	An error occurs	if the decoded
       key does	not match type.	 d2i_PublicKey() does the same for public
       keys.

       d2i_AutoPrivateKey() is similar to d2i_PrivateKey() except it attempts
       to automatically	detect the private key format.

       i2d_PrivateKey()	encodes	key. It	uses a key specific format or, if none
       is defined for that key type, PKCS#8 unencrypted	PrivateKeyInfo format.
       i2d_PublicKey() does the	same for public	keys.

       These functions are similar to the d2i_X509() functions;	see
       d2i_X509(3).

NOTES
       All these functions use DER format and unencrypted keys.	Applications
       wishing to encrypt or decrypt private keys should use other functions
       such as d2i_PKCS8PrivateKey() instead.

       If the *a is not	NULL when calling d2i_PrivateKey() or
       d2i_AutoPrivateKey() (i.e. an existing structure	is being reused) and
       the key format is PKCS#8	then *a	will be	freed and replaced on a
       successful call.

RETURN VALUES
       d2i_PrivateKey()	and d2i_AutoPrivateKey() return	a valid	EVP_KEY
       structure or NULL if an error occurs. The error code can	be obtained by
       calling ERR_get_error(3).

       i2d_PrivateKey()	returns	the number of bytes successfully encoded or a
       negative	value if an error occurs. The error code can be	obtained by
       calling ERR_get_error(3).
