The macro <b>DECLARE_PEM_rw</b> expands to the set of declarations shown in the next four lines of the synopsis.</p> <p>These routines convert between local instances of ASN1 datatypes and the PEM encoding. For more information on the templates, see <a href="../man3/ASN1_ITEM.html">ASN1_ITEM(3)</a>. For more information on the lower-level routines used by the functions here, see <a href="../man3/PEM_read.html">PEM_read(3)</a>.</p> <p>PEM_read_TYPE() reads a PEM-encoded object of <i>TYPE</i> from the file <b>fp</b> and returns it. The <b>cb</b> and <b>u</b> parameters are as described in <a href="../man3/pem_password_cb.html">pem_password_cb(3)</a>.</p> <p>PEM_read_bio_TYPE() is similar to PEM_read_TYPE() but reads from the BIO <b>bp</b>.</p> <p>PEM_write_TYPE() writes the PEM encoding of the object <b>a</b> to the file <b>fp</b>.</p> <p>PEM_write_bio_TYPE() similarly writes to the BIO <b>bp</b>.</p> <h1 id="NOTES">NOTES</h1> <p>These functions make no assumption regarding the pass phrase received from the password callback. It will simply be treated as a byte sequence.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>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.</p> <p>PEM_write_TYPE() and PEM_write_bio_TYPE() return the number of bytes written or zero on error.</p> <h1 id="SEE-ALSO">SEE ALSO</h1> <p><a href="../man3/PEM_read.html">PEM_read(3)</a>, <a href="../man7/passphrase-encoding.html">passphrase-encoding(7)</a></p> <h1 id="COPYRIGHT">COPYRIGHT</h1> <p>Copyright 1998-2018 The OpenSSL Project Authors.
