ApkSigner library Multiplatform

1. Sign with jks/bks, pk8 + x509.pem
2. Convert jks to bks, bks to jks, jks/bks to pk8 + x509.pem
3. Validate password
4. Create jks/bks

Add it in your root build.gradle at the end of repositories:

    allprojects {
        repositories {
            //...
            maven { url 'https://jitpack.io' }
        }
    }

Add the dependency

    dependencies {
        implementation 'com.github.TimScriptov:apksigner:Tag'
    }

Sign apk with pk8 and x509.pem

    v3SigningEnabled = true
    v4SigningEnabled = false
}.signRelease(
    File("path/key.pk8"),
    File("path/key.x509.pem"),
)

final ApkSigner signer = new ApkSigner(new File("path/unsigned_apk.apk"), new File("path/signed_apk.apk"));
signer.setUseDefaultSignatureVersion(false);
signer.setV1SigningEnabled(true);
signer.setV2SigningEnabled(true);
signer.setV3SigningEnabled(true);
signer.setV4SigningEnabled(false);
signer.signRelease(new File("path/key.pk8"), new File("path/key.x509.pem"));

Sign apk with jks/bks

}.signRelease(
    File("path/key.jks or key.bks"),
    "cert_pass",
    "cert_alias",
