#include <openssl/pem.h> DECLARE_PEM_rw(name, TYPE) TYPE *PEM_read_TYPE(FILE *fp, TYPE **a, pem_password_cb *cb, void *u); TYPE *PEM_read_bio_TYPE(BIO *bp, TYPE **a, pem_password_cb *cb, void *u); int PEM_write_TYPE(FILE *fp, const TYPE *a); int PEM_write_bio_TYPE(BIO *bp, const TYPE *a);
DESCRIPTION
In the description below,TYPE
is used
as a placeholder for any of the OpenSSL datatypes, such as X509.
The macro DECLARE_PEM_rw expands to the set of declarations shown in
the next four lines of the synopsis.
These routines convert between local instances of
ASN1
datatypes and
the PEM
encoding. For more information on the templates, see
(3). For more information on the lower-level routines used
by the functions here, see PEM_read(3).
PEM_read_TYPE() reads a PEM-encoded object of
TYPE
from the file fp
and returns it. The cb and u parameters are as described in
pem_password_cb(3).
PEM_read_bio_TYPE() is similar to PEM_read_TYPE() but reads from the
BIO
bp.
PEM_write_TYPE() writes the
PEM
encoding of the object a to the file fp.
PEM_write_bio_TYPE() similarly writes to the
BIO
bp.
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(), orNULL
on error.
PEM_write_TYPE() and PEM_write_bio_TYPE() return the number of bytes written or zero on error.
