jarsigner

Just recently I have had a problem with a key store. I know there are plenty of questions about this problem already. I have read them all and Googled furiously. Error: keytool error: java.io.IOException: Keystore was tampered with, or password was incorrect java.io.IOException: Keystore was tampered with, or password was incorrect at sun.security.provider.JavaKeyStore.engineLoad(JavaKeyStore.java:772) at sun.security.provider.JavaKeyStore$JKS.engineLoad(JavaKeyStore.java:55) at java.security.KeyStore.load(KeyStore.java:1214) at sun.security.tools.KeyTool.doCommands(KeyTool.java:885) at sun

I recently uploaded my application to the android market however it's refusing to run when downloaded due to the error Package file was not signed correctly I first published the packet using eclipse, right click export, creating a keystore then publishing, however it refuses to work. I then downloaded the keytool and jarsigner and used them to sign an upgrade which I posted instead. However this gives the same error. I have no idea what I've done wrong, and since I cannot delete the application I cannot try and start again can anyone help me? Thanks You have your debug copy still installed on

I'm wanting to sign a jar using jarsigner, then verify it using a Java application which does not have the signed jar as part of it's classpath (i.e. just using a filesystem location of the jar) Now my problem is getting the signature file out of the jar, is there a simple way to do this? I've had a play with the Inflater and Jar InputStreams with no luck. Or is this something that can be accomplished in a better way? Thanks The security Provider implementation guide outlines the process of verifying JARs. Although these instructions are for a JCA cryptographic service provider to verify

I need to sign Android application ( .apk ). I have .pfx file. I converted it to .cer file via Internet Explorer and then converted .cer to .keystore using keytool. Then I've tried to sign .apk with jarsigner but it says that .keystore doesn't content a private key. What I'm doing wrong? Using JDK 1.6 or later It has been pointed out by Justin in the comments below that keytool alone is capable of doing this using the following command (although only in JDK 1.6 and later): keytool -importkeystore -srckeystore mypfxfile.pfx -srcstoretype pkcs12 -destkeystore clientcert.jks -deststoretype JKS

The Java Security dialog is shown when loading a signed applet. What does the Java Security dialog look like? The security dialog might appear differently (and have different text) depending on the circumstances, but it looks roughly as above. If the 'digital signature cannot be verified' as in that message in the dialog, then: Always trust will default to false. It will be ignored even if selected. No Name or Publisher will appear. That image shows the prompt as it appears in older JREs. Here is how the NASA World Wind prompt appears in a Java 7 JRE for a verified certificate that has expired
