EVP_PKEY2PKCS8(3SSL)                OpenSSL               EVP_PKEY2PKCS8(3SSL)

NAME
       EVP_PKEY2PKCS8, EVP_PKCS82PKEY_ex, EVP_PKCS82PKEY - Convert a private
       key to/from PKCS8

SYNOPSIS
        #include <openssl/x509.h>

        PKCS8_PRIV_KEY_INFO *EVP_PKEY2PKCS8(const EVP_PKEY *pkey);
        EVP_PKEY *EVP_PKCS82PKEY(const PKCS8_PRIV_KEY_INFO *p8);
        EVP_PKEY *EVP_PKCS82PKEY_ex(const PKCS8_PRIV_KEY_INFO *p8, OSSL_LIB_CTX *libctx,
                                    const char *propq);

DESCRIPTION
       EVP_PKEY2PKCS8() converts a private key pkey into a returned PKCS8
       object.

       EVP_PKCS82PKEY_ex() converts a PKCS8 object p8 into a returned private
       key.  It uses libctx and propq when fetching algorithms.

       EVP_PKCS82PKEY() is similar to EVP_PKCS82PKEY_ex() but uses default
       values of NULL for the libctx and propq.

RETURN VALUES
       EVP_PKEY2PKCS8() returns a PKCS8 object on success.  EVP_PKCS82PKEY()
       and EVP_PKCS82PKEY_ex() return a private key on success.

       All functions return NULL if the operation fails.
