Add missing entries to NAME section Add SYNOPSIS lines, remove old NAME entries Update find-doc-nits; better regexp's for parsing SYNOPSIS sections. Rename a couple of files to have an API name. Remove RSA_private_decrypt; it was duplicate content Update for recent doc additions Reviewed-by: Matt Caswell <matt@openssl.org>

=head1 NAME
|
|
|
|
d2i_PrivateKey, d2i_AutoPrivateKey, i2d_PrivateKey,
|
|
d2i_PrivateKey_bio, d2i_PrivateKey_fp
|
|
- decode and encode functions for reading and saving EVP_PKEY structures
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/evp.h>
|
|
|
|
EVP_PKEY *d2i_PrivateKey(int type, EVP_PKEY **a, const unsigned char **pp,
|
|
long length);
|
|
EVP_PKEY *d2i_AutoPrivateKey(EVP_PKEY **a, const unsigned char **pp,
|
|
long length);
|
|
int i2d_PrivateKey(EVP_PKEY *a, unsigned char **pp);
|
|
|
|
EVP_PKEY *d2i_PrivateKey_bio(BIO *bp, EVP_PKEY **a);
|
|
EVP_PKEY *d2i_PrivateKey_fp(FILE *fp, EVP_PKEY **a)
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
d2i_PrivateKey() decodes a private key using algorithm B<type>. It attempts to
|
|
use any key specific format or PKCS#8 unencrypted PrivateKeyInfo format. The
|
|
B<type> parameter should be a public key algorithm constant such as
|
|
B<EVP_PKEY_RSA>. An error occurs if the decoded key does not match B<type>.
|
|
|
|
d2i_AutoPrivateKey() is similar to d2i_PrivateKey() except it attempts to
|
|
automatically detect the private key format.
|
|
|
|
i2d_PrivateKey() encodes B<key>. It uses a key specific format or, if none is
|
|
defined for that key type, PKCS#8 unencrypted PrivateKeyInfo format.
|
|
|
|
These functions are similar to the d2i_X509() functions; see L<d2i_X509(3)>.
|
|
|
|
=head1 NOTES
|
|
|
|
All these functions use DER format and unencrypted keys. Applications wishing
|
|
to encrypt or decrypt private keys should use other functions such as
|
|
d2i_PKC8PrivateKey() instead.
|
|
|
|
If the B<*a> is not NULL when calling d2i_PrivateKey() or d2i_AutoPrivateKey()
|
|
(i.e. an existing structure is being reused) and the key format is PKCS#8
|
|
then B<*a> will be freed and replaced on a successful call.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
d2i_PrivateKey() and d2i_AutoPrivateKey() return a valid B<EVP_KEY> structure
|
|
or B<NULL> if an error occurs. The error code can be obtained by calling
|
|
L<ERR_get_error(3)>.
|
|
|
|
i2d_PrivateKey() returns the number of bytes successfully encoded or a
|
|
negative value if an error occurs. The error code can be obtained by calling
|
|
L<ERR_get_error(3)>.
