How to verify an APK checksum and signing certificate

File checksum and signing identity are different

The Lucky Patcher release details publish two SHA-256 values. The file checksum identifies the exact bytes of the downloadable APK. The signing-certificate fingerprint identifies the certificate used to sign it. Comparing one value with the other will never establish that your download matches.

A matching file checksum tells you that your file matches the reference you compared it with. It does not independently prove that the reference is trustworthy, that the application is safe, or that it is an official Lucky Patcher release. This download is an independent, debug-signed reconstruction.

Compare your APK with the published checksum

Download the APK and the published checksum file from this site. In the folder containing the APK, calculate its SHA-256 value using a local file-hashing tool. For example, on macOS:

shasum -a 256 lp-rebuild-0.5.0-debug.apk

In Windows PowerShell:

Get-FileHash .\lp-rebuild-0.5.0-debug.apk -Algorithm SHA256

Compare the complete 64-character value with File SHA-256 in Build details, or with the value beside the same filename in SHA256SUMS.txt. Letter case does not matter; all hexadecimal digits must match.

Use the checksum for the same release. A different build can legitimately have different bytes, size and checksum even when its app name looks identical. The filename alone does not establish a match.

Check the signing certificate separately

If you already have Android SDK Build Tools installed, Android’s apksigner tool can verify an APK signature and print its signing certificates:

apksigner verify --verbose --print-certs lp-rebuild-0.5.0-debug.apk

Compare the signer certificate’s SHA-256 digest with Signing certificate SHA-256 in the release details. This is a different check from hashing the APK file. A valid signature establishes that the signed APK verifies; it does not certify its behaviour or make a debug certificate an official publisher identity.

You do not need to install the APK on a phone to perform these desktop checks. Read the official apksigner reference if the tool reports a verification problem.

If a value does not match

Pause before installing. Check that you selected the current Lucky Patcher file, that the download finished, and that you compared the file digest with the file digest rather than the certificate fingerprint. Download a fresh copy from the project’s download link if necessary.

If the mismatch persists, keep the filename and the value you calculated and contact support. Do not rename an unrelated APK and assume that makes it the same release.

Once you have finished checking the file, the installation guide explains what to expect from Android’s prompts.
