1=pod 2 3=head1 NAME 4 5EVP_PKEY2PKCS8, EVP_PKCS82PKEY_ex, EVP_PKCS82PKEY 6- Convert a private key to/from PKCS8 7 8=head1 SYNOPSIS 9 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 17=head1 DESCRIPTION 18 19EVP_PKEY2PKCS8() converts a private key I<pkey> into a returned PKCS8 object. 20 21EVP_PKCS82PKEY_ex() converts a PKCS8 object I<p8> into a returned private key. 22It uses I<libctx> and I<propq> when fetching algorithms. 23 24EVP_PKCS82PKEY() is similar to EVP_PKCS82PKEY_ex() but uses default values of 25NULL for the I<libctx> and I<propq>. 26 27=head1 RETURN VALUES 28 29EVP_PKEY2PKCS8() returns a PKCS8 object on success. 30EVP_PKCS82PKEY() and EVP_PKCS82PKEY_ex() return a private key on success. 31 32All functions return NULL if the operation fails. 33 34=head1 SEE ALSO 35 36L<PKCS8_pkey_add1_attr(3)>, 37 38=head1 COPYRIGHT 39 40Copyright 2020-2022 The OpenSSL Project Authors.
