SYNOPSIS

        #include <openssl/evp.h>

        EVP_PKEY *d2i_PKCS8PrivateKey_bio(BIO *bp, EVP_PKEY **x, pem_password_cb *cb, void *u);
        EVP_PKEY *d2i_PKCS8PrivateKey_fp(FILE *fp, EVP_PKEY **x, pem_password_cb *cb, void *u);

        int i2d_PKCS8PrivateKey_bio(BIO *bp, EVP_PKEY *x, const EVP_CIPHER *enc,
                                    char *kstr, int klen,
                                    pem_password_cb *cb, void *u);

        int i2d_PKCS8PrivateKey_fp(FILE *fp, EVP_PKEY *x, const EVP_CIPHER *enc,
                                   char *kstr, int klen,
                                   pem_password_cb *cb, void *u);

        int i2d_PKCS8PrivateKey_nid_bio(BIO *bp, EVP_PKEY *x, int nid,
                                        char *kstr, int klen,
                                        pem_password_cb *cb, void *u);

        int i2d_PKCS8PrivateKey_nid_fp(FILE *fp, EVP_PKEY *x, int nid,
                                       char *kstr, int klen,
                                       pem_password_cb *cb, void *u);


DESCRIPTION

       The PKCS#8 functions encode and decode private keys in PKCS#8 format
       using both PKCS#5 v1.5 and PKCS#5 v2.0 password based encryption
       algorithms.

       Other than the use of DER as opposed to PEM these functions are
       identical to the corresponding PEM function as described in
       PEM_read_PrivateKey(3).


NOTES

       These functions are currently the only way to store encrypted private
       keys using DER format.

       Currently all the functions use BIOs or FILE pointers, there are no
       functions which work directly on memory: this can be readily worked
       around by converting the buffers to memory BIOs, see BIO_s_mem(3) for
       details.

       These functions make no assumption regarding the pass phrase received
       from the password callback.  It will simply be treated as a byte
       sequence.


RETURN VALUES

       d2i_PKCS8PrivateKey_bio() and d2i_PKCS8PrivateKey_fp() return a valid
       EVP_PKEY structure or NULL if an error occurred.

       i2d_PKCS8PrivateKey_bio(), i2d_PKCS8PrivateKey_fp(),
       i2d_PKCS8PrivateKey_nid_bio() and i2d_PKCS8PrivateKey_nid_fp() return 1
       on success or 0 on error.
