I recently upgraded bcryptjs to version ^3.0.0 in my Node.js project and encountered the following error while trying to hash a password:

const bcrypt = require("bcryptjs");

const password = "mypassword";
const hashedPassword = bcrypt.hashSync(password, 10);

console.log(hashedPassword);

Error:

Error: Neither WebCryptoAPI nor a crypto module is available. Use bcrypt.setRandomFallback to set an alternative

What I Tried:

• I checked if the crypto module is available in my Node.js environment.
• I attempted to set a fallback using bcrypt.setRandomFallback(() => require("crypto").randomBytes(16));, but the issue persisted.

Node.js version is v18.18.0

Solution:

I downgraded bcryptjs to version ^2.4.3, and the issue was resolved:

npm install [email protected]

Now, password hashing works without errors.

Question:

• Why does bcryptjs v3.0.0 require WebCryptoAPI or an external crypto module, while v2.4.3 works fine?
• Is there a proper way to make it work with v3.0.0 without downgrading?

Hope this helps others facing the same issue!
