Adobe AIR project: .p12 & password

Do you have empty password string? Note that such error will be reported by IDEA if the password is empty: https://youtrack.jetbrains.com/issue/IDEA-125867 .
If the problem is different, could you please clarify: does the command from command line work? Can you attach sample project to check?

If to have sample project is not possible, please attach a screenshot showing where do you set the password and the complete textual output from Run.Debug session with the error.

No, I'm not in the case of a blank password.

Here is a screenshot of the context where it happens:

It also happens when I launch Debug, but then nothing more happens and I don't seem to get any related output...? All I can do is close the password box, and I get no other error message whatsoever.

If it can help, here is a screenshot of the output by the certutil command applied to the p12 file:

Please note that the process above required the p12 password, and it worked.

I did this following a colleague's guidance. He thinks there might be some sort of incompatibility between SHA1 & Java 8...?

Coming from FlashBuilder, I'm not familiar with command lines. Please let me know which command line I should type to generate a relevant output.

I could send you a sample project, but really, the problem seems to lie within the p12. Would you need the p12 file plus password?

Thank you very much for your help.

Thank you for the information.

>I did this following a colleague's guidance. He thinks there might be some sort of incompatibility between SHA1 & Java 8...?

Please see https://youtrack.jetbrains.com/issue/IDEA-176227 - Java 8u121 and later drop support for 1024 bit RSA certificate and 2048 bit certificate would be needed.

Thank you for your help.

I have tested with a new, compliant certificate, and it works.

Do you think there's a way I could downgrade to a former Java version in order to make the initial certificate work?

"Java 8 is required to run IntelliJ IDEA", so I think the answer might be just "no"?

This is really, really annoying that I cannot use the same certificate as before to sign the apk...

OK I finally managed to compile with the old certificate.

I downgraded IntelliJ to the latest version compatible with 1024, using the Choose Runtime plug-in.

Can you please direct me to the link in which I can downgrade IntelliJ? I'm also stuck with this problem. Thanks!

IntelliJ > "Choose Runtime" 

https://plugins.jetbrains.com/plugin/12836-choose-runtime

Once I clicked install, It crashed my InteliiJ unfortunately and now I cannot start it, thanks anyway Denis

If you can't start the IDE to access this dialog or the runtime doesn't change. You would need to remove the <product>.jdk file from the configuration directory and unset any environment variables that override the default runtime. If there is no jbrsubdirectory in the IDE installation directory, reinstall the product.

Sorry about that Mikthailand :(

Are you on a Mac? It worked for me on a Windows PC, but I think a colleague on Mac couldn't achieve the process either.

Thanks for the help, I ended up putting the the 1024 in a keystore I created, uploading it to Google Play to activate their signing, then asking them to reset the upload key with a new 2048 I will generate.
So far they didn't answer but it should work.
I think it's a good approach since it upgrades the key and google signing is on.
Thanks!
