crypto.scryptSync regression in Node 15: routines:EVP_PBE_scrypt:memory limit exceeded #35815
Description
- Version: 15.0.1
- Platform: Linux 64 bits
- Subsystem: crypto
What steps will reproduce the bug?
Create main.js and run it.
// main.js
const crypto = require("crypto");
// 2-3 iteration steps are enough to cause the error, but it's not deterministic so I am running it 100 times to make sure the error occurs
for (let i = 0; i < 100; i++) {
crypto.scryptSync('', '', 64, { N: 128, r: 1, p: 1 })
}
How often does it reproduce? Is there a required condition?
Calling scryptSync a few times always produces this error. This is not deterministic: sometimes 2 calls were enough, sometimes I need 3 calls.
What is the expected behavior?
The script completes without any error
What do you see instead?
I see the following error:
node:internal/crypto/scrypt:81
throw err;
^

Additional information
This is a regression in Node 15. Running the same code on the same computer with Node 14.14.0 works fine.
