A comprehensive, modular, and production-ready security toolkit for Android apps. Includes encryption, hashing, biometric authentication, keychain management, root/debugger/simulator/reverse engineering detection, app integrity checks, network security, random data generation, and screen shield features.
- Encryption: AES-128, AES-256
- Hashing: MD5, SHA-1, SHA-256, SHA-512, HMAC-SHA256, HMAC-SHA512
- Biometric Authentication: Face ID, Touch ID, fallback to device passcode
- Keychain Management: Securely store, retrieve, update, and delete sensitive data
- Root, Debugger, Simulator, Reverse Engineering Detection
- App Integrity Checks: Code signing, file hashes, tampering
- Network Security: Proxy/VPN detection, certificate pinning, SSL validation
- Random Data Generation: Secure random strings, passwords, UUIDs, tokens
- Screen Shield: Prevent screenshots, prevent screen recording, blur on background
- Kotlin Coroutines: Async/await support for all major operations
- Jetpack Compose compatible
Add the dependency to yourbuild.gradle:
implementation("com.yourorg:android-security-toolkit:latest-version")val appSecurity=AppSecurity.initialize(context)
val activity= contextas?FragmentActivityif (appSecurity.isBiometricAvailable(activity)) {val biometricUtils= appSecurity.createBiometricUtils( config= appSecurity.config.biometric, activity= activity, authCallback=object:BiometricUtils.AuthCallback {overridefunonAuthSuccessful(promptType:BiometricUtils.PromptType) {// Handle success }overridefunonAuthError(promptType:BiometricUtils.PromptType,errorCode:Int,errString:CharSequence) {// Handle error }overridefunonAuthFailed(promptType:BiometricUtils.PromptType) {// Handle failure } } ) biometricUtils.displayBiometricPrompt(BiometricUtils.PromptType.ENABLE_BIOMETRIC_LOGIN)}
val encrypted= appSecurity.encrypt("secret".toByteArray(),EncryptionAlgorithm.AES_256,"password")val decrypted= appSecurity.decrypt(encrypted,EncryptionAlgorithm.AES_256,"password")
val hash= appSecurity.hash("my data",HashingAlgorithm.SHA_256)
appSecurity.storeStringInKeychain("mySecret","keyAlias")val value= appSecurity.retrieveStringFromKeychain("keyAlias")
val isValid= appSecurity.verifyAppIntegrity()
val isSecure= appSecurity.checkNetworkSecurity()
appSecurity.enableScreenShield(activity)
