=head1 SYNOPSIS

|
|
||
|
|
#include <openssl/pem.h>
|

=head1 DESCRIPTION
|
||
|
|
|
||
|
|
b2i_PVK_bio_ex() decodes a private key of MSBLOB format read from a B<BIO>. It
|
||
|
|
attempts to automatically determine the key type. If the key is encrypted then
|
||
|
|
I<cb> is called with the user data I<u> in order to obtain a password to decrypt
|
||
|
|
the key. The supplied library context I<libctx> and property query
|
||
|
|
string I<propq> are used in any decrypt operation.
|
||
|
|
|
||
|
|
b2i_PVK_bio() does the same as b2i_PVK_bio_ex() except that the default
|
||
|
|
library context and property query string are used.
|
||
|
|
|
||
|
|
i2b_PVK_bio_ex() encodes I<pk> using MSBLOB format. If I<enclevel> is 1 then
|
||
|
|
a password obtained via I<pem_password_cb> is used to encrypt the private key.
|
||
|
|
If I<enclevel> is 0 then no encryption is applied. The user data in I<u> is
|
||
|
|
passed to the password callback. The supplied library context I<libctx> and
|
||
|
|
property query string I<propq> are used in any decrypt operation.
|
||
|
|
|
||
|
|
i2b_PVK_bio() does the same as i2b_PVK_bio_ex() except that the default
|
||
|
|
library context and property query string are used.
|
||
|
|
|
||
|
|
=head1 RETURN VALUES
|
||
|
|
|
||
|
|
The b2i_PVK_bio() and b2i_PVK_bio_ex() functions 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)>.
|
||
|
|
|
||
|
|
i2b_PVK_bio() and i2b_PVK_bio_ex() return 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)>.
