|
||||
|
||||
These functions read and decode PEM-encoded objects, returning the
|
||||
PEM type B<name>, any encapsulation B<header> and the decoded
|
||||
These functions read and write PEM-encoded objects, using the PEM
|
||||
type B<name>, any additional B<header> information, and the raw
|
||||
B<data> of length B<len>.
|
||||
|
||||
PEM_read() reads from the stdio file handle B<fp>, while PEM_read_bio() reads
|
||||
from the BIO B<bio>.
|
||||
PEM is the term used for binary content encoding first defined in IETF
|
||||
RFC 1421. The content is a series of base64-encoded lines, surrounded
|
||||
by begin/end markers each on their own line. For example:
|
||||
|
||||
-----BEGIN PRIVATE KEY-----
|
||||
MIICdg....
|
||||
... bhTQ==
|
||||
-----END PRIVATE KEY-----
|
||||
|
||||
Optional header line(s) may appear after the begin line, and their
|
||||
existence depends on the type of object being written or read.
|
||||
|
||||
PEM_write() writes to the file B<fp>, while PEM_write_bio() writes to
|
||||
the BIO B<bp>. The B<name> is the name to use in the marker, the
|
||||
B<header> is the header value or NULL, and B<data> and B<len> specify
|
||||
the data and its length.
|
||||
|
||||
The final B<data> buffer is typically an ASN.1 object which can be decoded with
|
||||
the B<d2i> function appropriate to the type B<name>; see L<d2i_X509(3)>
|
||||
for examples.
|
||||
|
||||
PEM_read() reads from the file B<fp>, while PEM_read_bio() reads
|
||||
from the BIO B<bp>.
|
||||
Both skip any non-PEM data that precedes the start of the next PEM object.
|
||||
When an object is successfuly retrieved, the type name from the "----BEGIN
|
||||
<type>-----" is returned via the B<name> argument, any encapsulation headers

|

=head1 DESCRIPTION
|
||||
|
||||
In the description below, I<TYPE> is used
|
||||
as a placeholder for any of the OpenSSL datatypes, such as I<X509>.
|
||||
|
||||
These routines convert between local instances of ASN1 datatypes and
|
||||
the PEM encoding. For more information on the templates, see
|
||||
L<ASN1_ITEM(3)>. For more information on the lower-level routines used
|
||||
by the functions here, see L<PEM_read(3)>.
|
||||
|
||||
PEM_read_TYPE() reads a PEM-encoded object of I<TYPE> from the file B<fp>
|
||||
and returns it. The B<cb> and B<u> parameters are as described in
|
||||
L<pem_password_cb(3)>.
|
||||
|
||||
PEM_read_bio_TYPE() is similar to PEM_read_TYPE() but reads from the BIO B<bp>.
|
||||
|
||||
PEM_write_TYPE() writes the PEM encoding of the object B<a> to the file B<fp>.
|
||||
|
||||
PEM_write_bio_TYPE() similarly writes to the BIO B<bp>.
|
||||
|
||||
=head1 RETURN VALUES
|
||||
|
||||
PEM_read_TYPE() and PEM_read_bio_TYPE() return a pointer to an allocated
|
||||
object, which should be released by calling TYPE_free(), or NULL on error.
|
||||
|
||||
PEM_write_TYPE() and PEM_write_bio_TYPE() return the number of bytes written
|
||||
or zero on error.

=head1 DESCRIPTION
|
||||
|
||||
In the description below, I<TYPE> is used
|
||||
as a placeholder for any of the OpenSSL datatypes, such as I<X509>.
|
||||
|
||||
The OpenSSL ASN1 parsing library templates are like a data-driven bytecode
|
||||
interpreter.
|
||||
Every ASN1 object as a global variable, TYPE_it, that describes the item
|
||||
such as its fields. (On systems which cannot export variables from shared
|
||||
libraries, the global is instead a function which returns a pointer to a
|
||||
static variable.
|
||||
|
||||
The macro DECLARE_ASN1_FUNCTIONS() is typically used in header files
|
||||
to generate the function declarations.
|
||||
|
||||
The macro IMPLEMENT_ASN1_FUNCTIONS() is used once in a source file
|
||||
to generate the function bodies.
|
||||
|
||||
|
||||
TYPE_new() allocates an empty object of the indicated type.
|
||||
The object returned must be released by calling TYPE_free().
|
||||
|
||||
TYPE_dup() copies an existing object.
|
||||
|
||||
TYPE_free() releases the object and all pointers and sub-objects
|
||||
within it.
|
||||
|
||||
TYPE_print_ctx() prints the object B<a> on the specified BIO B<out>.
|
||||
Each line will be prefixed with B<indent> spaces.
|
||||
The B<pctx> specifies the printing context and is for internal
|
||||
use; use NULL to get the default behavior. If a print function is
|
||||
user-defined, then pass in any B<pctx> down to any nested calls.
|
||||
|
||||
=head1 RETURN VALUES
|
||||
|
||||
TYPE_new() and TYPE_dup() return a pointer to the object or NULL on failure.
|
||||
|
||||
TYPE_print_ctx() returns 1 on success or zero on failure.
