Hi everyone, I can't solve this problem, it's been weeks but nothing ...
i try to bundle app on project but it says:
file signing AAB Error
jarsigner error: java.security.SignatureException: private key algorithm is not compatible with signature algorithm
I tried to create a new key, to update sdk, to directly make a new project, to update b4a but I don't get out ... help me. it is also urgent as a job but I am now at a standstill.

Use the latest version of B4A.
Carefully follow the installation instructions: https://www.b4x.com/b4a.html
No need to update anything.
Create a new sign key if you are using an old one.

errore jarsigner: java.security.SignatureException: l'algoritmo della chiave privata non è compatibile con l'algoritmo della firma

ho aggiornato tutto con nuova chiave, ecco qua che dà ancora errore @Erel

Try it with OpenJDK 11: https://www.b4x.com/b4a.html

hi @Erel , i uninstalled everything and reinstalled from scratch doing step by step b4a installation, having everything updated.
i created a new project and created a new private key ... i have the usual problem: jarsigner error: java.security.SignatureException: private key algorithm is not compatible with signature algorithm.
I do not know what else to do because if I had to do something else it goes beyond my skills and I am also unable to publish the app which has a certain urgency because it is for a municipal body.

You are still not using Java 11.

@Erel
as i have windows x86 and what i download from this site: https://www.oracle.com/java/technologies/downloads/#java8-windows is the java i'm using right now.
since nobody can help me and I see indifference, can you help me and understand how to put java 11 on windows x86 if the site where to download everything you need for b4a gives me java 8?
thank you...

Hi, sorry but I didn't see any indifference. Erel posted the link where you'll find instructions on how to install OpenJDK 11, instead this Java 11. See post #5 again.

here are the steps https://www.b4x.com/b4a.html

Hello @Never99

I don't know if JDK 11 runs on 32-bit architecture (Windows x86).

On the JDK 11 download page I only see 64-bit versions, official link: https://www.oracle.com/co/java/technologies/javase/jdk11-archive-downloads.html

In several forums they state that it is possible to work on 32 bits, see this link: https://adoptium.net/releases.html?variant=openjdk11

I hope you can solve that problem, although it would be easy to find a 64-bit windows computer.

I have already written above that I have done all of these steps but it doesn't work anyway

Is that how you have it configured?

in javac.exe i have: C:\Java\jdk1.8.0_321\bin\javac.exe
here: https://www.oracle.com/java/technologies/downloads/#java8
it is the most updated on the b4a site for installation

Why don't you use a 64-bit Windows?

solved with C:\Java\jdk-17.0.1\bin\javac.exe
