<h1><a name="description">DESCRIPTION</a></h1>
|
|
<p><code>PEM_read_bio_ex()</code> reads in PEM formatted data from an input BIO, outputting
|
|
the name of the type of contained data, the header information regarding
|
|
the possibly encrypted data, and the binary data payload (after base64 decoding).
|
|
It should generally only be used to implement PEM_read_bio_-family functions
|
|
for specific data types or other usage, but is exposed to allow greater flexibility
|
|
over how processing is performed, if needed.</p>
|
|
<p>If PEM_FLAG_SECURE is set, the intermediate buffers used to read in lines of
|
|
input are allocated from the secure heap.</p>
|
|
<p>If PEM_FLAG_EAY_COMPATIBLE is set, a simple algorithm is used to remove whitespace
|
|
and control characters from the end of each line, so as to be compatible with
|
|
the historical behavior of <code>PEM_read_bio()</code>.</p>
|
|
<p>If PEM_FLAG_ONLY_B64 is set, all characters are required to be valid base64
|
|
characters (or newlines); non-base64 characters are treated as end of input.</p>
|
|
<p>If neither PEM_FLAG_EAY_COMPATIBLE or PEM_FLAG_ONLY_B64 is set, control characters
|
|
are ignored.</p>
|
|
<p>If both PEM_FLAG_EAY_COMPATIBLE and PEM_FLAG_ONLY_B64 are set, an error is returned;
|
|
these options are not compatible with each other.</p>

<p>The caller must release the storage allocated for *name, *header, and *data.
|
|
If PEM_FLAG_SECURE was set, use <code>OPENSSL_secure_free()</code>; otherwise,
|
|
<code>OPENSSL_free()</code> is used.</p>
