NAME

6       EVP_PKEY2PKCS8, EVP_PKCS82PKEY_ex, EVP_PKCS82PKEY - Convert a private
7       key to/from PKCS8
8

SYNOPSIS

10        #include <openssl/x509.h>
11
12        PKCS8_PRIV_KEY_INFO *EVP_PKEY2PKCS8(const EVP_PKEY *pkey);
13        EVP_PKEY *EVP_PKCS82PKEY(const PKCS8_PRIV_KEY_INFO *p8);
14        EVP_PKEY *EVP_PKCS82PKEY_ex(const PKCS8_PRIV_KEY_INFO *p8, OSSL_LIB_CTX *libctx,
15                                    const char *propq);
16

DESCRIPTION

18       EVP_PKEY2PKCS8() converts a private key pkey into a returned PKCS8
19       object.
20
21       EVP_PKCS82PKEY_ex() converts a PKCS8 object p8 into a returned private
22       key.  It uses libctx and propq when fetching algorithms.
23
24       EVP_PKCS82PKEY() is similiar to EVP_PKCS82PKEY_ex() but uses default
25       values of NULL for the libctx and propq.
26

RETURN VALUES

28       EVP_PKEY2PKCS8() returns a PKCS8 object on success.  EVP_PKCS82PKEY()
29       and EVP_PKCS82PKEY_ex() return a private key on success.
30
31       All functions return NULL if the operation fails.
