SHA-256 fingerprint
8F:B2:3F:4A:E8:46:1A:90:52:B0:6A:5D:E9:5B:3A:F4:6C:E1:9B:D3:88:6B:64:0F:AC:9A:CE:1B:C3:62:91
Any other fingerprint means the APK was re-signed. Delete it immediately.
CLI methods
Use the Android SDK apksigner
1
Install SDK Platform Tools
Download from Google and unzip.
2
Run apksigner verify
apksigner verify --print-certs 1xbet.apk
Look for the SHA-256 digest line in the output.
3
Compare with the official fingerprint
If it matches, the APK is authentic. Otherwise, discard the file.
GUI methods
Android Studio APK Analyzer
What to check
- SHA-256 digest equals
8F:B2:…:91. - “Signer #1” references 1X Corp N.V.
- No warning icons or “not signed” messages.
Android-only
Use an on-device signature app
Recommended apps
- APK Signature Verification (by Tachi Y).
- APK Analyzer (by Appteka).
Steps
- Install the verifier from Google Play.
- Select
1xbet.apkfrom your downloads. - Confirm the fingerprint matches the official value.
Watch out
Never grant these verifier apps network permissions. They only need storage access to read the APK.
Automation
Scripting the check
Bash example
#!/bin/bash
EXPECTED="8FB23F4AE8461A9052B06A5DE95B3AF46CE19BD3886B640FAC9ACE1BC36291"
RESULT=$(apksigner verify --print-certs 1xbet.apk | grep "SHA-256" | awk '{print $3}')
if [ "$RESULT" = "$EXPECTED" ]; then
echo "Signature OK"
else
echo "Signature mismatch!"
fi
PowerShell example
$expected = "8FB23F4AE8461A9052B06A5DE95B3AF46CE19BD3886B640FAC9ACE1BC36291"
$result = & .\apksigner.bat verify --print-certs 1xbet.apk |
Select-String "SHA-256" | % { $_.ToString().Split(":")[-1].Trim() }
if ($result -eq $expected) { "Signature OK" } else { "Mismatch!" }
Troubleshooting
Common verification issues
“apksigner not found”
Add the SDK platform-tools folder to your PATH or run apksigner with its full path.
“File isn’t signed” message
You downloaded an unsigned or repackaged build. Delete it and re-download from the official link.
Fingerprint mismatch
Never install the APK. Clear your cache, fetch a new copy, and report the suspicious file to support@conjugationapp.com.
APK Analyzer crashes
Update Android Studio or fall back to the CLI methods.
Best practices
Stay vigilant for every release
Hash + signature combo
- Always run the SHA-256 hash and signature checks together.
- Archive both values for each version you install.
- Share verification logs with teammates for transparency.
Limit APK sources
- Only use /link/ or approved mirrors.
- Bookmark trusted domains to avoid phishing.
- Ignore unsolicited APK links from chats or forums.
FAQ
Signature verification questions
