Question 1

How does jsHashes compare to Node.js crypto module for hashing?

Accepted Answer

jsHashes is a pure JavaScript library that works across platforms, while Node.js crypto is native and faster but limited to Node.js. Use jsHashes for consistency in cross-environment apps, but switch to crypto for server-side performance.

Question 2

How to use jsHashes for HMAC in a browser?

Accepted Answer

Instantiate the HMAC class with a key and string, then call methods like hex_hmac() or b64_hmac(). For example, 'new Hashes.SHA1().hex_hmac(key, data)' generates an HMAC-SHA1 hash in hexadecimal format directly in the browser.

Question 3

Does jsHashes support SHA-3 or other modern algorithms?

Accepted Answer

No, jsHashes only supports MD5, SHA1, SHA256, SHA512, RIPEMD-160, and HMAC. The README states there are no plans to add more algorithms, so for SHA-3, you'd need a different library.

Question 4

Can jsHashes hash files in Node.js?

Accepted Answer

No, jsHashes only handles string inputs, not files. The README explicitly mentions it doesn't support checksum hashing for files, so you'd need to read files as strings first or use another tool like Node.js crypto for file hashing.

Question 5

Is jsHashes secure for password hashing?

Accepted Answer

While it implements standard algorithms, password hashing requires specialized techniques like salting and slow hashing (e.g., bcrypt). jsHashes provides basic hashes, so for passwords, use dedicated libraries like bcrypt.js in addition to or instead of jsHashes.

Question 6

How to install jsHashes with npm and use it in a project?

Accepted Answer

Run 'npm install jshashes', then require it in Node.js with 'var Hashes = require('jshashes')'. In browsers, include the script directly or use a CDN, then instantiate classes like 'new Hashes.MD5()' to start hashing.
