secure-random-string
Node.js module that generates a cryptographically secure random string with a given length
Usage
var srs = require('secure-random-string');
Default behavior: Generate a random string 32 characters long.
// Sync
var result = srs();
// Async
srs(function(sr) {
console.log(sr);
});
Options: length, urlsafe
Optionally, you can specify a 'length' option to specify a length.
The 'urlsafe' option replaces a potential + character with - and the / character
with _, created a valid base64url format string.
// sync
var result = srs({length: 256, urlsafe:true});
// async
srs({length: 256, urlsafe:true}, function(sr) {
console.log(sr);
});
Error handling
Will throw error if there is not enough accumulated entropy to generate cryptographically strong data. In other words, this without callback will not block even if all entropy sources are drained.
