keybox.xml

format:

<?xml version="1.0"?>
<AndroidAttestation>
    <NumberOfKeyboxes>1</NumberOfKeyboxes>
    <Keybox DeviceID="...">
        <Key algorithm="ecdsa|rsa">
            <PrivateKey format="pem">
-----BEGIN EC PRIVATE KEY-----
...
-----END EC PRIVATE KEY-----
            </PrivateKey>
            <CertificateChain>
                <NumberOfCertificates>...</NumberOfCertificates>
                    <Certificate format="pem">
-----BEGIN CERTIFICATE-----
...
-----END CERTIFICATE-----
                    </Certificate>
                ... more certificates
            </CertificateChain>
        </Key>...
    </Keybox>
</AndroidAttestation>

Support TEE broken devices

Tricky Store will hack the leaf certificate by default. On TEE broken devices, this will not work because we can't retrieve the leaf certificate from TEE. You can add a ! after a package name to enable generate certificate support for this package.

For example:

# target.txt
# use leaf certificate hacking mode for KeyAttestation App
io.github.vvb2060.keyattestation
# use certificate generating mode for gms
com.google.android.gms!

Customize security patch level

Edit the file /data/adb/tricky_store/devconfig.toml.

For example:

securityPatch = "2024-04-05"
osVersion = 34

TODO

• Support automatic selection mode.
