base32-encoding

base32-encoding

Encode / decode base32. Supports Buffers, strings, custom alphabets, abstract-encoding compliant

Usage

var base32 = require('base32-encoding')

var buf = crypto.randomBytes(32)

var b32 = base32.encode(buf)
var b256 = base32.decode(b32)

var str = base32.stringify(buf) // base32.encode then convert to string
var origBuf = base32.parse(str) // convert from string then base32.decode

API

var output = base32.encode(buf, [output], [offset])

Encode a normal Buffer as base32, meaning only the lower 5 bits are used. Takes ⌈len * 8 / 5⌉ bytes to encode. Takes optional Buffer output instead of allocating a new Buffer internally, and writes at optional offset. Returns output. Sets base32.encode.bytes to the number of bytes written.

var output = base32.decode(buf, [output], [offset])

Decode a base32 Buffer as a normal, "base256" Buffer, meaning only the lower 5 bits are read from buf and assembled into complete 8 bit bytes. Takes ⌊len * 5 / 8⌋ bytes to encode. Takes optional Buffer output instead of allocating a new Buffer internally, and writes at optional offset. Returns output. Sets base32.decode.bytes to the number of bytes written.

var len = base32.encodingLength(buf)

Returns ⌈len * 8 / 5⌉.

var str = base32.stringify(buf, [alphabet])

Encode buf to base32 and translate into a string using optional alphabet. alphabet defaults to 23456789abcdefghijkmnpqrstuvwxyz (missing o01l).

var buf = base32.parse(str, [alphabet])

Decode str from base32 and translate from a string using optional alphabet. alphabet defaults to 23456789abcdefghijkmnpqrstuvwxyz (missing o01l).
