=head1 DESCRIPTION
|
|
|
|
PEM_X509_INFO_read_ex() loads the B<X509_INFO> objects from a file I<fp>.
|
|
|
|
PEM_X509_INFO_read() is similar to PEM_X509_INFO_read_ex()
|
|
but uses the default (NULL) library context I<libctx>
|
|
and empty property query I<propq>.
|
|
|
|
PEM_X509_INFO_read_bio_ex() loads the B<X509_INFO> objects using a bio I<bp>.
|
|
|
|
PEM_X509_INFO_read_bio() is similar to PEM_X509_INFO_read_bio_ex()
|
|
but uses the default (NULL) library context I<libctx>
|
|
and empty property query I<propq>.
|
|
|
|
Each of the loaded B<X509_INFO> objects can contain a CRL, a certificate,
|
|
and/or a private key.
|
|
The elements are read sequentially, and as far as they are of different type than
|
|
the elements read before, they are combined into the same B<X509_INFO> object.
|
|
The idea behind this is that if, for instance, a certificate is followed by
|
|
a private key, the private key is supposed to correspond to the certificate.
|
|
|
|
If the input stack I<sk> is NULL a new stack is allocated,
|
|
else the given stack is extended.
|
|
|
|
The optional I<cb> and I<u> parameters can be used for providing a pass phrase
|
|
needed for decrypting encrypted PEM structures (normally only private keys).
|
|
See L<PEM_read_bio_PrivateKey(3)> and L<passphrase-encoding(7)> for details.
|
|
|
|
The library context I<libctx> and property query I<propq> are used for fetching
|
|
algorithms from providers.
