Requires you to implement 2 methods `_final` and `_update`. `_update` takes a buffer and should return a buffer, `_final` takes no arguments and should return a buffer. The constructor takes one argument and that is a string which if present switches it into hash mode, i.e. the object you get from crypto.createHash or crypto.createSign, this switches the name of the final method to be the string you passed instead of `final` and returns `this` from update. browserify-cipher-base-99535ac/index.js000066400000000000000000000101651472142523700201100ustar00rootroot00000000000000'use strict';
