TLS/SSL Certificate Key Size Too Small

Severity: Medium

Invicti detected that certificates used by your server uses a key that is considered weak due to its small key size. The recommended minimum sizes for RSA and ECDSA keys are 2,048 bit and 256 bit, respectively.


It can impact both website and the users:

  • Warning error messages displayed by browsers when visiting the site
  • Personal information at risk from man-in-the-middle attacks
  • Reduction in trust as the site becomes insecure

If you are using certificates with weak keys, you will need to migrate to either larger keys, more efficient algorithms, or both.
