Other [FIXED] Error while verifying Sign Key

[lemonisdead]

Hello,
I am asking the community because I was unable to find the answer using a search engine.

I had to change my computer and reinstalled the necessary tools. I had the copy of my Sign Key (generated in 2013) but was unable to use it because of an error while associating with B4A.
So I have generated a new sign key with B4A yesterday. Today, I have got the same error.

Below is a screenshot and attached a fake sign key with password "testing" if someone would like to test it.

Please, is this on my part ? How could I fix that ? Thanks

It works fine here:

What happens if you try to compile with this key?

Thanks

What happens if you try to compile with this key?

When I try to compile I get an error at the end of the compilation window:

Signing package file (private key). Error
jarsigner error: java.security.InvalidKeyException: The security strength of SHA-1 digest algorithm is not sufficient for this key size

and that, even with my old key

Please test it with Java 8u102 from this page: http://www.oracle.com/technetwork/java/javase/downloads/java-archive-javase8-2177648.html
