javax.crypto.BadPaddingException: Given final block not properly padded about javapns HOT 15 CLOSED

Something is wrong with your cert.

Where are you storing the cert? In what format? How did it get there? etc....

Same problem here.  It worked fine on a different machine, so I'm not sure 
what's wrong.

I'm storing the certificate as a file, "testcert.p12".  I emailed it to myself 
from the machine I made it on (Keychain app -> select developer and push cert, 
export).  I've re-made and re-emailed it to myself so I don't think it was a 
transmission error.  I'm working with Eclipse Helios on a Windows 7 machine, 
with JDK 1.5.

I assume you are using the jdk 1.5 version.

Sounds like the SSL certificate isn't loading properly... what happens when you 
enable ssl certificate logging as per:
http://code.google.com/p/javapns/wiki/Tips

You say you 'emailed it to myself'...

Are you sure the file didn't get binhex encoded or modified in transit?

Does the filesize match on the originating machine and target machine?

Can you find a better way to copy the file? ftp? winscp? sneakernet?

Can you verify that java can load the file at all?

bdares, were you able to solve the issue you reported?  Was it related to your 
keystore format or password?  May we close this issue as fixed?  Thank you!

Issue suspected of being caused by invalid password for given keystore.

Closing issue as no feedback was received by original poster since issue was 
reported.  
Please feel free to re-open if the issue is still valid.

if we wanna decrypt a encrypted file than this exception arise (file is 
encrypted). 
but if we encrypt file n thank decrypt in same code thank code execute 
successfully

can some help me please

I do not understand what you mean.  Please provide a copy of the code you are 
trying to run, and the exception (with stack trace) you are getting.  Thank you.

I configure my tomcat using server.p12  , I get the following error

Your code is not even using the JavaPNS library...  Are you requesting support 
in a project you are not using?  Or am I missing something here...

go to function extractPrivateKey()
and change alias and password

I want to encrypt with certificate private key (.pfx) and decrypt with public 
key.
