获取Android应用程序的签名

获取签名

private byte[] getSign(Context context) {        PackageManager pm = context.getPackageManager();        List apps = pm                .getInstalledPackages(PackageManager.GET_SIGNATURES);        Iterator iter = apps.iterator();        while (iter.hasNext()) {            PackageInfo info = iter.next();            String packageName = info.packageName;            //按包名 取签名            if (packageName.equals("com.iceskysl.test")) {                return info.signatures[0].toByteArray();            }        }        return null;    }

获取公钥

public static String getPublicKey(byte[] signature) {        try {            CertificateFactory certFactory = CertificateFactory                    .getInstance("X.509");            X509Certificate cert = (X509Certificate) certFactory                    .generateCertificate(new ByteArrayInputStream(signature));            String publickey = cert.getPublicKey().toString();            publickey = publickey.substring(publickey.indexOf("modulus: ") + 9,                    publickey.indexOf("\n", publickey.indexOf("modulus:")));            Log.d("TRACK", publickey);            return publickey;        } catch (CertificateException e) {            e.printStackTrace();        }        return null;    }
