keytool : Certificate import gives error message - Keystore was tampered with, or password was incorrect

Question

My goal is to generate a certificate, export it in a file and import in JDK keystore.

In first step I have generated a self signed certificate using following command, providing password as 'password' for keystore and key:

keytool   -genkeypair  -keystore .keystore  -alias uasera  -keyalg RSA

In second step I exported the certificate using similar password and following command:

keytool  -exportcert  -keystore  .keystore  -alias usera  -file usera.crt

NOW!

I am trying to import this certificate in cacerts in JDK using similar password and following command but getting exception.

keytool -importcert -file usera.crt -keypass password  -keystore "C:\Program Files\Java\jdk1.7.0_13\jre\lib\security\cacerts"

ERROR

K:\java\certificates>keytool -importcert -file usera.crt -keypass password -keystore "C:\Program Files\Java\jdk1.7.0_13\jre\lib\security\cacerts" Enter keystore password: keytool error: java.io.IOException: Keystore was tampered with, or password was incorrect

Answer 1

I have got this sorted out. I was using my password that is 'password' to update cacerts keystore in JDK while default password for cacerts keystore is 'changeit'
