copied!<p>I believe I came across one by Paul Johnston at <a href="http://pajhome.org.uk/crypt/md5/contrib/sha1_stream.js" rel="nofollow noreferrer">http://pajhome.org.uk/crypt/md5/contrib/sha1_stream.js</a> . It is listed on the page <a href="http://pajhome.org.uk/crypt/md5/scripts.html" rel="nofollow noreferrer">http://pajhome.org.uk/crypt/md5/scripts.html</a> . I have not tested it myself, but I have used his non-streamable version that he modified for it.</p> <p>UPDATE: Here is some example code (I verified it against a separate SHA1 known to be correct). Make sure you include the original sha1.js (found at <a href="http://pajhome.org.uk/crypt/md5/sha1.js" rel="nofollow noreferrer">http://pajhome.org.uk/crypt/md5/sha1.js</a>) before the streamable sha1_stream.js.</p> <pre><code><script src="sha1.js" type="text/javascript" charset="utf-8"></script> <script src="sha1_stream.js" type="text/javascript" charset="utf-8"></script> <script type="text/javascript" charset="utf-8"> var input = 'abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz'; var blocksize = 512; var h = naked_sha1_head(); for (var i = 0; i < input.length; i += blocksize) { var len = Math.min(blocksize, input.length - i); var block = input.substr(i, len); naked_sha1(str2binb(block), len*chrsz, h); } var result = binb2hex(naked_sha1_tail(h)); </script> </code></pre>
