How to verify Android version Eddie's signature

[Carampa 0]

Hi, 

I'd like to know how to verify Android version Eddie's signature.
we can verify the SHA256 hash here, but that's only part of the necessary verification steps.
The level of information required for verification is provided, for example, by Signal
Apksigner on Eddie.apk returns:

$ apksigner verify -v --print-certs --min-sdk-version 24 "EddieAndroid-4.1.0VC40.apk"
Verifies
Verified using v1 scheme (JAR signing): false
Verified using v2 scheme (APK Signature Scheme v2): true
Verified using v3 scheme (APK Signature Scheme v3): false
Verified using v3.1 scheme (APK Signature Scheme v3.1): false
Verified using v4 scheme (APK Signature Scheme v4): false
Verified for SourceStamp: false

Can anyone provide info to compare and verify?
Many thanks! Edited ... by Carampa

Hello!

The SHA-256 checksum published on our website is provided specifically to allow users who sideload Eddie to verify the APK they downloaded.

The APK is also cryptographically signed. The certificate fingerprint shown by apksigner can be used to verify the signing certificate of the APK, but the SHA-256 checksum published on our website is the reference we currently provide for independently verifying the downloaded APK.

We may consider publishing the signing certificate fingerprint as additional information, now that we publish the APK already signed.

Kind regards
