Compatible with Android 8.0 (API level 26) to Android 13 (API level 33)

Fully supports validation and signing for the following formats:

1. ASiC-E with CAdES
2. ASiC-E with XAdES
3. PAdES

To include this port in your project, add the following to your build.gradle file:

repositories {
   maven {
      url = uri("https://maven.pkg.github.com/signerry/packages")
      credentials {
         username = System.getenv("GPR_USER")
         password = System.getenv("GPR_API_KEY")
      }
   }
}

dependencies {
    api "com.signerry.dss-android:dss-xades:1.01.20"
    api "com.signerry.dss-android:dss-asic-common:1.01.20"
    api "com.signerry.dss-android:dss-asic-xades:1.01.20"
    api "com.signerry.dss-android:dss-asic-cades:1.01.20"
}

• GPR_USER: Your GitHub username
• GPR_API_KEY: Your GitHub personal access token with read:packages scope

Tests are performed for both unit and instrumented levels. Instrumented tests are executed on an Android emulator. All stock DSS tests pass with a few exceptions, mostly related to visual signatures. The following tests are not passing and have been disabled:

1. dss-xades:
   • XAdESLevelBEnvelopingManifestReferenceCanonicalizationTest
   • XAdESLevelBReSignOJManifestTest
2. dss-pades-pdfbox:
   • Visual textFullyTransparentTest
   • Visual multilinesWithDpiTest
   • Visual testWithCMYKImage
   • Visual rotationTest
3. dss-pades:
   • PAdESSignatureDigestRefPresenceTest (Same issue in stock DSS 5.12.RC1)
   • testDoubleSignature (Fails randomly due emulator to time shift issue)
4. dss-tsl-validation
   • skTLTest
5. dss-cades
   • CAdESMultipleCounterSignatureExtensionTest (Disabled due to expired timestamp)

Because certain standard Java SDK functionalities are unavailable on Android, the following third-party libraries are used as substitutes:

This DSS project consists of several modules. The table below indicates which modules have been ported:

A sample signature validation application is available on the Google Play Store.
