+# adler32
+
+Signed ADLER-32 algorithm implementation in JS (for the browser and nodejs).
+Emphasis on correctness, performance, and IE6+ support.
+
+## Installation
+
+With [npm](https://www.npmjs.org/package/adler-32):
+
+```bash
+$ npm install adler-32
+```
+
+In the browser:
+
+```html
+<script src="adler32.js"></script>
+```
+
+The browser exposes a variable `ADLER32`.
+
+When installed globally, npm installs a script `adler32` that computes the
+checksum for a specified file or standard input.
+
+The script will manipulate `module.exports` if available .  This is not always
+desirable.  To prevent the behavior, define `DO_NOT_EXPORT_ADLER`.
+
+## Usage
+
+In all cases, the relevant function takes an argument representing data and an
+optional second argument representing the starting "seed" (for running hash).
+
+The return value is a signed 32-bit integer.
+
+- `ADLER32.buf(byte array or buffer[, seed])` assumes the argument is a sequence
+  of 8-bit unsigned integers (nodejs `Buffer`, `Uint8Array` or array of bytes).
+
+- `ADLER32.bstr(binary string[, seed])` assumes the argument is a binary string
+  where byte `i` is the low byte of the UCS-2 char: `str.charCodeAt(i) & 0xFF`
+
+- `ADLER32.str(string)` assumes the argument is a standard JS string and
+  calculates the hash of the UTF-8 encoding.
+
+For example:
+
+```js
+// var ADLER32 = require('adler-32');           // uncomment if in node
+ADLER32.str("SheetJS")                          // 176947863
+ADLER32.bstr("SheetJS")                         // 176947863
+ADLER32.buf([ 83, 104, 101, 101, 116, 74, 83 ]) // 176947863
+
+adler32 = ADLER32.buf([83, 104])                // 17825980  "Sh"
+adler32 = ADLER32.str("eet", adler32)           // 95486458  "Sheet"
+ADLER32.bstr("JS", adler32)                     // 176947863  "SheetJS"
+
+[ADLER32.str("\u2603"),  ADLER32.str("\u0003")]  // [ 73138686, 262148 ]
+[ADLER32.bstr("\u2603"), ADLER32.bstr("\u0003")] // [ 262148,   262148 ]
+[ADLER32.buf([0x2603]),  ADLER32.buf([0x0003])]  // [ 262148,   262148 ]
+```
+
+## Testing
+
+`make test` will run the nodejs-based test.
+
+To run the in-browser tests, run a local server and go to the `ctest` directory.
+`make ctestserv` will start a python `SimpleHTTPServer` server on port 8000.
+
+To update the browser artifacts, run `make ctest`.
+
+To generate the bits file, use the `adler32` function from python `zlib`:
+
+```python
+>>> from zlib import adler32
+>>> x="foo bar baz٪☃🍣"
+>>> adler32(x)
+1543572022
+>>> adler32(x+x)
+-2076896149
+>>> adler32(x+x+x)
+2023497376
+```
+
+The included `adler32.njs` script can process files or standard input:
+
+```bash
+$ echo "this is a test" > t.txt
+$ bin/adler32.njs t.txt
+726861088
+```
+
+For comparison, the included `adler32.py` script uses python `zlib`:
+
+```bash
+$ bin/adler32.py t.txt
+726861088
+```
+
+## Performance
+
+`make perf` will run algorithmic performance tests (which should justify certain
+decisions in the code).
+
+Bit twiddling is much faster than taking the mod in Safari and Firefox browsers.
+Instead of taking the literal mod 65521, it is faster to keep it in the integers
+by bit-shifting: `65536 ~ 15 mod 65521` so for nonnegative integer `a`:
+
+```
+    a = (a >>> 16) * 65536 + (a & 65535)            [equality]
+    a ~ (a >>> 16) * 15    + (a & 65535) mod 65521
+```
+
+The mod is taken at the very end, since the intermediate result may exceed 65521
+
+## Magic Number
+
+The magic numbers were chosen so as to not overflow a 31-bit integer:
+
+```mathematica
+F[n_] := Reduce[x*(x + 1)*n/2 + (x + 1)*(65521) < (2^31 - 1) && x > 0, x, Integers]
+F[255] (* bstr:  x \[Element] Integers && 1 <= x <= 3854 *)
+F[127] (* ascii: x \[Element] Integers && 1 <= x <= 5321 *)
+```
+
+Subtract up to 4 elements for the Unicode case.
