Security Bulletin: IBM Security Verify Information Queue uses a relatively weak cryptographic algorithm to protect application data (CVE-2021-20406)

Summary

The cryptographic algorithm that IBM Security Verify Information Queue (ISIQ) uses to encrypt and decrypt application data has a JSON web token (JWT) signing key that is shorter than the recommended length. As of v10.0.0, ISIQ has doubled the length of its JWT signing key to be in compliance.
