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.
