FIPS mode is not available.
Example 2:
index.js
// Node.js program to demonstrate the // crypto.setFips() method // Importing crypto module const crypto = require('crypto') // Enabling the FIPS compliant // crypto provider by using // setFips() method try { // Function call const val = crypto.setFips(false); // Display the result console.log("FIPS compliant crypto " + "provider has been disabled"); } catch (e) { console.log("ERR_CRYPTO_FIPS_UNAVAILABLE") } |
