<p>X509_ALGOR_dup, X509_ALGOR_set0, X509_ALGOR_get0, X509_ALGOR_set_md, X509_ALGOR_cmp - AlgorithmIdentifier functions</p>
<h1 id="SYNOPSIS">SYNOPSIS</h1>
<pre><code> #include &lt;openssl/x509.h&gt;
X509_ALGOR *X509_ALGOR_dup(X509_ALGOR *alg);
int X509_ALGOR_set0(X509_ALGOR *alg, ASN1_OBJECT *aobj, int ptype, void *pval);
void X509_ALGOR_get0(const ASN1_OBJECT **paobj, int *pptype,
const void **ppval, const X509_ALGOR *alg);
void X509_ALGOR_set_md(X509_ALGOR *alg, const EVP_MD *md);

<h1 id="DESCRIPTION">DESCRIPTION</h1>
<p>X509_ALGOR_dup() returns a copy of <b>alg</b>.</p>
<p>X509_ALGOR_set0() sets the algorithm OID of <b>alg</b> to <b>aobj</b> and the associated parameter type to <b>ptype</b> with value <b>pval</b>. If <b>ptype</b> is <b>V_ASN1_UNDEF</b> the parameter is omitted, otherwise <b>ptype</b> and <b>pval</b> have the same meaning as the <b>type</b> and <b>value</b> parameters to ASN1_TYPE_set(). All the supplied parameters are used internally so must <b>NOT</b> be freed after this call.</p>
<p>X509_ALGOR_get0() is the inverse of X509_ALGOR_set0(): it returns the algorithm OID in <b>*paobj</b> and the associated parameter in <b>*pptype</b> and <b>*ppval</b> from the <b>AlgorithmIdentifier</b> <b>alg</b>.</p>
<p>X509_ALGOR_set_md() sets the <b>AlgorithmIdentifier</b> <b>alg</b> to appropriate values for the message digest <b>md</b>.</p>
<p>X509_ALGOR_cmp() compares <b>a</b> and <b>b</b> and returns 0 if they have identical encodings and non-zero otherwise.</p>
<h1 id="RETURN-VALUES">RETURN VALUES</h1>
<p>X509_ALGOR_dup() returns a valid <b>X509_ALGOR</b> structure or NULL if an error occurred.</p>
<p>X509_ALGOR_set0() returns 1 on success or 0 on error.</p>
<p>X509_ALGOR_get0() and X509_ALGOR_set_md() return no values.</p>
<p>X509_ALGOR_cmp() returns 0 if the two parameters have identical encodings and non-zero otherwise.</p>
