Summary

The remote SSL/TLS server certificate and/or any of the certificates in the certificate chain is using a RSA key with less than 1024 bits.

Insight

Insight

SSL/TLS certificates using RSA keys with less than 1024 bits are considered unsafe.

Detection Method

Detection Method

Checks the RSA keys size of the server certificate and all certificates in chain for a size < 1024 bit.

Solution

Solution

Replace the certificate with a stronger key and reissue the certificates it signed.
