[java] keytool error Keystore was tampered with, or password was incorrect

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.

Please share your inputs.

Works on Windows

open command prompt (press Windows Key + R then type "cmd" without quotations in the appearing dialogue box and then press Enter Key).

then type the code sniff below :

1. cd C:\Program Files\Java\jdk1.7.0_25\bin

then type following command

2. keytool -list -keystore "C:/Documents and Settings/Your Name/.android/debug.keystore"

Then it will ask for Keystore password now. The default password is "android" type and enter or just hit enter "DONT TYPE ANY PASSWORD".

This answer will be helpful for new Mac User (Works for Linux, Window 7 64 bit too).

Empty Password worked in my mac . (paste the below line in terminal)

keytool -list -v -keystore ~/.android/debug.keystore

when it prompt for

Enter keystore password:  

just press enter button (Dont type anything).It should work .

Please make sure its for default debug.keystore file , not for your project based keystore file (Password might change for this).

Works well for MacOS Sierra 10.10+ too.

I heard, it works for linux environment as well. i haven't tested that in linux yet.

I solved it by using the default password for cacerts keystore : 'changeit'

In tomcat 8.5 pay attention to write the correct name of attributes. This is my code on server.xml:

<Connector port="8443" protocol="org.apache.coyote.http11.Http11NioProtocol"
           maxThreads="150" SSLEnabled="true">
    <SSLHostConfig>
        <Certificate certificateKeystoreFile="conf/keystore" certificateKeystorePassword="mypassword" type="RSA"/>
    </SSLHostConfig>
</Connector>

You can visit https://tomcat.apache.org/tomcat-8.5-doc/config/http.html to see all attributes

For me I solved it by changing passwords from Arabic letter to English letter, but first I went to the folder and deleted the generated key then it works.

In my case with Xamarin Forms 4.7 and Visual Studio 2019 16.7.0 Preview 3.1, the problem was version mismatch of lately updated Android Build tools (apksigner) and JDK. Updated JDK to latest and pointed the new JDK path on Tools->Options->Xamarin->Android Settings, and it works.

In my case I was needed to have root access.

keytool error: java.io.IOException: Keystore was tampered with, or password was incorrect

I solved my problem when I changed keystore path C:\MyWorks\mykeystore to C:\MyWorks\mykeystore.keystore.

Empty password worked for me on my Mac

keytool -list -v -keystore ~/.android/debug.keystore 

hit Enter then It's show you

Enter keystore password:  

here just hit Enter for empty password

 [root@localhost Certificate]# openssl pkcs12 -export -in 
 /opt/Certificate/115c99f4c5aa98f5.crt -inkey /opt/Certificate/ravi.in.key -certfile 
/opt/Certificate/gd_bundle-g2-g1.crt -out RaviNew.p12

Enter Export Password: <Password>
Verifying - Enter Export Password: <Password>

Note :- Above Export Pasworrd write down anywhere because it is must to create JKS file ( It is depend on your choice what password you want to make )

  keytool -importkeystore -srckeystore DigiEduNew.p12 -srcstoretype pkcs12 -destkeystore finaldigiEdu.jks -deststoretype JKS
  Importing keystore DigiEduNew.p12 to finaldigiEdu.jks...
  Enter destination keystore password: <Any Password >
  Re-enter new password: <Any Password >
  Enter source keystore password: <.P12 Password >
  Entry for alias 1 successfully imported.
  Import command completed:  1 entries successfully imported, 0 entries failed or 
  cancelled



 Warning:
 The JKS keystore uses a proprietary format. It is recommended to migrate to PKCS12 
 which is an industry standard format using "keytool -importkeystore -srckeystore 
 finaldigiEdu.jks -destkeystore finaldigiEdu.jks -deststoretype pkcs12".

Summarizing the advices from this page, I finished up with the following:

keytool -genkeypair -keystore ~/.android/release.keystore -alias <my_alias> -storepass <my_cert_pass> -keyalg RSA

Then I got a set of questions regarding name, organization, location and password for my alias.

Check your home folder ~/.gradle/gradle.properties. Sometimes if you have gradle.properties in home directory it takes details from the there. Either you can change that or delete the files. Then it will take required details from your local folder.

Using changeit for the password is important too.

This command finally worked for me(with jetty):

 keytool -genkey -keyalg RSA -alias selfsigned -keystore keystore.jks -storepass changeit -validity 360 -keysize 2048

I fixed this issue by deleting the output file and running the command again. It turns out it does NOT overwrite the previous file. I had this issue when renewing a let's encrypt cert with tomcat

If you are working on signing your Flutter App by following this guide Build and release an Android app and run in to this error. I hope this answer helps you.

In my case I changed the path to store my key.jks. This happened to me because I there was an existing file in that path.

keytool -genkey -v -keystore ~/key.jks -keyalg RSA -keysize 2048 -validity 10000 -alias key

This command stores the key.jks file in your home directory. To store it elsewhere, change the argument you pass to the -keystore parameter.

In my case,

keytool -genkey -v -keystore /Users/Y/Desktop/X/key.jks -keyalg RSA -keysize 2048 -validity 10000 -alias keyYour

i.e Y - Username and X - folder name

Then you will be prompted to Enter keystore password: and Re-enter new password:. Here you can use whatever password you want.

However, keep the keystore file private; don’t check it into public source control!

The default password for the debug keystore is android.

I have solve this issue by using default password "changeit".
