Summary

Remove root certificates with 1024-bit RSA public keys from the cacerts keystore.

Problem

There are 5 root certificates with 1024-bit RSA public keys in the system-wide cacerts keystore. These roots should be removed as the key size is weak.

Specification

The keystore aliases listed in the Solution section will be removed from the {java.home}/lib/security/cacerts file. Since this file is binary, it is not possible to show a diff. The following files containing the certificates will be deleted from the JDK source code:

make/data/cacerts/thawtepremiumserverca
make/data/cacerts/verisignclass2g2ca
make/data/cacerts/verisignclass3ca
