Cipher.getInstance("AES/ECB/PKCS5Padding") not available

The implementation you are trying to access is simply not available.

What do you mean by that? Can you please explain?

I have this thing working on my machine wherein I get the instance of Cipher. And I have j2sdk1.4.2_03 on my machine.

This application throws the exception below on other machine which has got a different version of java:

Algorithm (AES/ECB/PKCS5Padding) is not available - Algorithm AES not available

Does that provide any hint?

Yes, AES is only available from 1.4 and onwards: http://java.sun.com/products/jce/index-14.html

Which means jce 1.2

Checks on file C:\j2sdk1.4.2\jre\lib\security\java.security has something like this

security.provider.4=com.sun.crypto.provider.SunJCE

The number isn't 4 is fine, and checks for file C:\j2sdk1.4.2\jre\lib\ext\sunjce_provider.jar exists on path.

P.S. JAVA_HOME is C:\j2sdk1.4.2 by assume.

I can use both AES/ECB/PKCS5Padding and Rijndael/ECB/PKCS5Padding with j2sdk1.4.2-b28.
