gencodings v0.0.4

gencodings provides two binary-to-text encodings and decodings for use in JavaScript, including Node.js. These are similar to Base64 encoding, in that they provide a way to represent binary data in pure ASCII.

GEncodings have a number of desirable properties, such as preserving order, having a 1-1 length relationship, and providing maximum information from partial data. The links below point to a fuller specification that explains the design.

This library provides these two GEncodings:

• G60 allows binary data to be rendered as an alphanumeric string.

• G86 is for rendering binary data more compactly by using nearly all ASCII characters, including punctuation. However, it still avoids characters that may be problematic in HTML/XML, source code, and cookies.

An existing encoding, Crockford Base-32, is recommended if it is desired to have a case-insensitive encoding, at the cost of requiring more characters.

Usage

The functions g60Encode, g60Decode, g86Encode, g86Decode are exported. Also exported are the objects G60 and G86, each of which have properties encode and decode.

The encoders take an ArrayBuffer and return a JavaScript string, while the decoders do the reverse.

import { G60, g86Decode } from "gencodings";

console.log(G60.encode(g86Decode("0H_fZQ{)BO)~boV#*k#m[R{{J2)ahL$Xwhks56l[")));
