<p>All of the functions described on this page are deprecated. Applications should use OSSL_ENCODER_to_bio() and OSSL_DECODER_from_bio() instead.</p>
|
||
|
|
|
||
|
|
<p>In the description below, <b><i>TYPE</i></b> is used as a placeholder for any of the OpenSSL datatypes, such as <b>X509</b>. 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><b>PEM_read_<i>TYPE</i></b>() reads a PEM-encoded object of <b><i>TYPE</i></b> from the file <i>fp</i> and returns it. The <i>cb</i> and <i>u</i> parameters are as described in <a href="../man3/pem_password_cb.html">pem_password_cb(3)</a>.</p>
|
||
|
|
|
||
|
|
<p><b>PEM_read_bio_<i>TYPE</i></b>() is similar to <b>PEM_read_<i>TYPE</i></b>() but reads from the BIO <i>bp</i>.</p>
|
||
|
|
|
||
|
|
<p><b>PEM_write_<i>TYPE</i></b>() writes the PEM encoding of the object <i>a</i> to the file <i>fp</i>.</p>
|
||
|
|
|
||
|
|
<p><b>PEM_write_bio_<i>TYPE</i></b>() similarly writes to the BIO <i>bp</i>.</p>

<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><b>PEM_read_<i>TYPE</i></b>() and <b>PEM_read_bio_<i>TYPE</i></b>() return a pointer to an allocated object, which should be released by calling <b><i>TYPE</i>_free</b>(), or NULL on error.</p>
|
||
|
|
|
||
|
|
<p><b>PEM_write_<i>TYPE</i></b>() and <b>PEM_write_bio_<i>TYPE</i></b>() return 1 for success or 0 for failure.</p>
