sha1

Beispiel

Beispiel 1

Berechnen Sie den SHA-1-Hash der Zeichenfolge "Hallo":

 <span class="token php language-php"><span class="token delimiter important"><? Php</span>
<span class="token variable">$ str</span> <span class="token operator">=</span> <span class="token string double-quoted-string">"Shanghai"</span> <span class="token punctuation">;</span>
<span class="token keyword">Echo</span> <span class="token function">SHA1</span> <span class="token punctuation">(</span> <span class="token variable">$ str</span> <span class="token punctuation">)</span> <span class="token punctuation">;</span>
<span class="token delimiter important">?></span></span>
