Interface to obtain secure random numbers. In the browser, bcrypt.js relies on Web Crypto API's getRandomValues Npm install bcryptjs var bcrypt = require( 'bcryptjs') On node.js, the inbuilt crypto module's randomBytes interface is used to obtain The library is compatible with CommonJS and AMD loaders and is exposed globally as dcodeIO.bcrypt if neither is The maximum input length is 72 bytes (note that UTF8 encoded characters use up to 4 bytes) and the length of generated While bcrypt.js is compatible to the C++ bcrypt binding, it is written in pure JavaScript and thus slower ( about 30%), effectively reducing the number of iterations that can be Iteration count can be increased to make it slower, so it remains resistant to brute-force search attacks even with Compatible to the C++ bcryptīinding on node.js and also working in the browser.īesides incorporating a salt to protect against rainbow table attacks, bcrypt is an adaptive function: over time, the Optimized bcrypt in JavaScript with zero dependencies.
