<p>PKCS12_add1_attr_by_NID, PKCS12_add1_attr_by_txt - Add an attribute to a PKCS#12 safeBag structure</p>

<h1 id="SYNOPSIS">SYNOPSIS</h1>

<pre><code>#include &lt;openssl/pkcs12.h&gt;

int PKCS12_add1_attr_by_NID(PKCS12_SAFEBAG *bag, int nid, int type,
                            const unsigned char *bytes, int len);
int PKCS12_add1_attr_by_txt(PKCS12_SAFEBAG *bag, const char *attrname, int type,
                            const unsigned char *bytes, int len);</code></pre>

<h1 id="DESCRIPTION">DESCRIPTION</h1>

<p>These functions add a PKCS#12 Attribute to the Attribute Set of the <b>bag</b>.</p>

<p>PKCS12_add1_attr_by_NID() adds an attribute of type <b>nid</b> with a value of ASN1 type <b>type</b> constructed using <b>len</b> bytes from <b>bytes</b>.</p>

<p>PKCS12_add1_attr_by_txt() adds an attribute of type <b>attrname</b> with a value of ASN1 type <b>type</b> constructed using <b>len</b> bytes from <b>bytes</b>.</p>

<h1 id="NOTES">NOTES</h1>

<p>These functions do not check whether an existing attribute of the same type is present. There can be multiple attributes with the same type assigned to a safeBag.</p>

<p>Both functions were added in OpenSSL 3.0.</p>

<h1 id="RETURN-VALUES">RETURN VALUES</h1>

<p>A return value of 1 indicates success, 0 indicates failure.</p>
