如何获取APK签名签名？
提问于 2011-04-07 17:27:29
有没有办法检索用于签署APK的密钥的签名？我用密钥库中的密钥签署了我的APK。如何以编程方式检索它？

您可以使用PackageManager类http://developer.android.com/reference/android/content/pm/PackageManager.html像这样访问APK的签名
Signature[] sigs = context.getPackageManager().getPackageInfo(context.getPackageName(), PackageManager.GET_SIGNATURES).signatures;
for (Signature sig : sigs)
{
Trace.i("MyApp", "Signature hashcode : " + sig.hashCode());
}我使用它与我的调试密钥的散列代码进行比较，以此作为识别APK是调试APK还是发布APK的一种方式。

包管理器将为您提供任何已安装包的签名证书。然后可以打印出签名密钥的详细信息，例如
final PackageManager packageManager = context.getPackageManager();
final List<PackageInfo> packageList = packageManager.getInstalledPackages(PackageManager.GET_SIGNATURES);
for (PackageInfo p : packageList) {
final String strName = p.applicationInfo.loadLabel(packageManager).toString();
final String strVendor = p.packageName;
sb.append("<br>" + strName + " / " + strVendor + "<br>");
final Signature[] arrSignatures = p.signatures;
for (final Signature sig : arrSignatures) {
/*
* Get the X.509 certificate.
*/
final byte[] rawCert = sig.toByteArray();
InputStream certStream = new ByteArrayInputStream(rawCert);
try {
CertificateFactory certFactory = CertificateFactory.getInstance("X509");
X509Certificate x509Cert = (X509Certificate) certFactory.generateCertificate(certStream);
sb.append("Certificate subject: " + x509Cert.getSubjectDN() + "<br>");
sb.append("Certificate issuer: " + x509Cert.getIssuerDN() + "<br>");
sb.append("Certificate serial number: " + x509Cert.getSerialNumber() + "<br>");
sb.append("<br>");
}
catch (CertificateException e) {
// e.printStackTrace();
}
}
