base58

An implementation of Base58 and Base58Check encodings for nodejs. Note, the implementation of Base58Check differs slightly from that described on Wikipedia in that it does not prepend a version byte onto the data being encoded. This implementation uses the bignum library (which is a native module and uses the openssl bignumber library functions).

NOTE: earlier versions of this package used native C code instead of bignum, but it was found to be unstable in a production environment (likely due to bugs in the C code). This version uses bignum and appears to be very stable, but slower. The C version of this package is still available on the "native-module" branch. A few additional methods added to bignum would probably bring the speed of this version on part with with C version.

Installation

npm install base58-native

Usage

var base58 = require('base58-native');
base58.encode(base58.decode('mqqa8xSMVDyf9QxihGnPtap6Mh6qemUkcu'));

var base58Check = require('base58-native').base58Check;
base58Check.encode(base58Check.decode('mqqa8xSMVDyf9QxihGnPtap6Mh6qemUkcu'));
