How should i solve it thanks

keytool -v -list -keystore xxx.jks
get CHECKSUM sha256
Still the same problem

Hi,

I don't think keytool is the right tool to generate sha256 checksum. Our deploy script generates checksum using linux command

sha256sum xxx.apk

Please note that using checksum is optional (although I recommend it as security precaution).

I have the same problem.
I calculated the checksum from the Windows prompt with the command:
certutil -hashfile <file_name> SHA256
and also with this command (Windows PowerShell):
get-filehash -Algorithm SHA256 <file_name>
I get the same result but the checksum is not accepted.

[MartinHlavna]

Hello,
could you create some sample apk and checksum you got?

[robman70]

Hello,
ok, as soon as I can I do it.
But in the meantime I tried to get the checksum through Linux sha256sum and I got the exact same checksum I get with windows.
For the moment I have disabled the checksum check ... :-(

Please note that using checksum is optional (although I recommend it as security precaution).

Being optional is not a solution. People got authority error.

Iis there anyone who found the propper way to make it working, please make a information note here.
