All of the functions described on this page are deprecated. Applications should use OSSL_ENCODER_to_bio() and OSSL_DECODER_from_bio() instead.
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 ASN1_ITEM (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.
These functions make no assumption regarding the pass phrase received from the password callback. It will simply be treated as a byte sequence.
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 1 for success or 0 for failure.
