I am getting following error while generating certificates on my local machine.

C:\Users\abc>keytool -genkey -alias tomcat -keyalg RSA
Enter keystore password:
keytool error: java.io.IOException: Keystore was tampered with, or password was incorrect

I think there is some problems in jdk version.I ran the same command on my collegues machine and it is working fine.

I was able to reproduce the error by mangling the trusted.certs file at directory

Java Keytool – Fix java.security.KeyStoreException: BKS Not Found

Your error indicates that keytool tries to instantiate a BKS keystore but no Cryptographic Service Provider (CSP) is able to provide such an implementation. BKS keystore type is a type implemented by the BouncyCastle CSP.

Therefore there is 2 solutions:

install this provider with Java. Oracle published along with Java a comprehensive documentation.
pass to keytool the suitable options to indicate which CSP should be used and its location:

-storetype BKS                                               <- keystore type
-provider org.bouncycastle.jce.provider.BouncyCastleProvider <- CSP implementation
-providerpath /path/to/bouncycastle.jar                      <- Path to the CSP jar file
