KeyTool error : java.lang.Exception : Alias does not exist

Question

I have sucessfully imported the certificate by below command:

keytool -import -alias "alias-name" -file 
  "C:\somepath\Certificate\portal.cer 
  -keystore C:\Program Files\Java\jdk1.7.0_79\jre\lib\cacerts"

Now I am trying to delete the imported certificate with

keytool -delete -alias "alias-name" -keystore 
     "C:\Program Files\Java\jdk1.7.0_79\jre\lib\cacerts" -storepass changeit

But I am end with the below error message:

KeyTool error : java.lang.Exception : Alias does not exist

Answer 1

For Ubuntu / Linux
List all entries from your keystore with the respective alias

keytool -list -v -keystore "myKeyStore.jks" -storepass myPassword

The verbose option '-v' is important, in order to see the aliases

Example output:

Keystore type: PKCS12
Keystore provider: SUN

Your keystore contains 2 entries

Alias name: 1
Creation date: Dec 4, 2019
Entry type: PrivateKeyEntry
Certificate chain length: 2
Certificate[1]:
Owner: CN=yourname.com, O=Your Name, C=XX

Serial number: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
