Abstract

LIC-UNPRED CERTIFICATES WITH MD2-RSA SIGNATURES

Error Description

Certificates signed with the MD2withRSA signature algorithm    
cause unpredictable results including system crash.

****************************************************************
Certificates signed with the MD2withRSA signature algorithm can
cause unpredictable results including the possibility of a      
system crash.                                                  

Problem Conclusion

LIC was missing a method to handle the MD2withRSA algorithm.    
The method was added.
