例1

文字列「hello」のsha-1ハッシュを計算します：

 <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>
