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
).
