for (android.content.pm.Signature signature : info.signatures) {
MessageDigest md = MessageDigest.getInstance("SHA");
md.update(signature.toByteArray());
String KeyHash = Base64.encodeToString(md.digest(), Base64.DEFAULT);
Log.e("HashKey=========", KeyHash);// 打印出來的HashKey就是秘鑰散列
}
} catch (Exception e) {
