=head1 NAME

EVP_PKEY2PKCS8, EVP_PKCS82PKEY_ex, EVP_PKCS82PKEY
|
|
- Convert a private key to/from PKCS8
|
|
|
|
=head1 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);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
EVP_PKEY2PKCS8() converts a private key I<pkey> into a returned PKCS8 object.
|
|
|
|
EVP_PKCS82PKEY_ex() converts a PKCS8 object I<p8> into a returned private key.
|
|
It uses I<libctx> and I<propq> when fetching algorithms.
|
|
|
|
EVP_PKCS82PKEY() is similar to EVP_PKCS82PKEY_ex() but uses default values of
|
|
NULL for the I<libctx> and I<propq>.
|
|
|
|
=head1 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.
