I've recently reinstalled B4A together with jdk1.8.0_151 and when I want to generate a new private key, I get this error:

B4X:

The security strength of SHA-1 digest algorithm is not sufficient for this key size

Might be linked to the info that can be found at http://www.oracle.com/technetwork/java/javase/8u151-relnotes-3850493.html

Solved by downgrading to JDK 1.8 102 (why does a jdk uninstall/install take so long....), but this is something that definitely needs to be addressed in the future.

I wasn't able to reproduce it. Tested with both Java 9 and the latest Java 8.

Were you using 32 bit Java?

I've got the same problem just after creating a private key
JDK 1.8.0.152

Using Debug key is OK
