Java Keytool jdk/jre 64/32bit - Is there a difference?

Question

I noticed, there are Java 4 different Keytool.exe(and jarsigner.exe) on my computer. For either Java 64bit or 32bit and either in the jdk and jre directory.

Does it make any difference, which one I use to sign my jars?

Answer 1

No, the functionality is the same. It's just included in the jre and the jdk, and if you happen to have several of them, you'll have several keytool.exes.
