Sorry I am a beginner about ssl cert. according to
http://tomcat.apache.org/tomcat-7.0-doc/ssl-howto.html#Create_a_local_Certificate_Signing_Request_(CSR) it will gen a keystore and CSR. we generate the CSR and send to Certificate Authority. What if I lost the keystore ? should I regen the CSR again to reapply the ssl cert? Refer to https://search.thawte.com/support/ssl-digital-certificates/index?page=content&id=SO832 It will generate a new keystore file. is it the file store the private key? which stated in https://search.thawte.com/support/ssl-digital-certificates/index?page=content&id=SO750 , which say 1. Private Key file loss. 2. Private Key pass phrase loss. 3. Private Key file has been compromised due to the server being hacked. ...... ......
