encode() with private key in “AndroidKeyStore” return null

我与影子孤独终老i 提交于 2019-12-01 04:12:46
问题 With Android 4.3, this code return null. KeyStore keyStore = KeyStore.getInstance("AndroidKeyStore"); keyStore.load(null); keyStore.setKeyEntry(alias, privateKey, null, certificateChain); PrivateKeyEntry entry=(PrivateKeyEntry)keyStore.getEntry(alias, new PasswordProtection(password)); assert(entry.getPrivateKey().getEncoded()!=null); How it's possible to get the encoded version of private key ? Or, is it possible to transmit the private key handler to another application ? Thank's 回答1: The

PHP RSA key creation

柔情痞子 提交于 2019-12-01 03:14:32
问题 I have an issue with creating/using RSA keys created and used in PHP. Problem is, that the (public AND private) keys should be exchanged between different servers (e.g. when a user account is moved). Now, the openssl-lib of PHP does not provide any detailed info on in what format the keys are created. The latest documentation at http://php.net/manual/en/function.openssl-pkey-export.php just states, that it is "in PEM format", but it does not say whether it is in PKCS#1 or PKCS#8 Additionally,

Configure SSL certificates with Hibernate, Spring and JDBC

I'm trying to move from an unencrypted JDBC connection using a username and password to log in to my MySQL database server, to a connection using SSL and certificate-based authentication. I'm using Hibernate with Spring MVC. My WebAppConfig file looks like this: package com.****.PolicyManager.init; import java.util.Properties; import javax.annotation.Resource; import javax.sql.DataSource; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.ComponentScan; import org.springframework.context.annotation.Configuration; import org.springframework.context

PKI multiple public keys

回眸只為那壹抹淺笑 提交于 2019-11-30 11:20:14
I'm wondering if I can have multiple public keys for a private key. Can this be done? If so, what are the security issues!? If I generate multiple key pairs based on the same initial values (with no initial vector), shouldn't the keys be "compatible"? In all asymmetric crypto-systems I can think off, there is a 1-1 correspondence between the public key and the private key: given the private key you can uniquely determine the public key and given the public key you can uniquely determine the private key (but it should of course be computationally infeasible to determine the private key from the

How do you present a different PKI client certificate to a server once you have already presented one, in Firefox?

南楼画角 提交于 2019-11-30 07:34:13
When I visit a website that requires PKI client certificates Firefox will allow the user to select which certificate to present. How do you present a different PKI client certificate to a server once you have already presented one, in Firefox? This blogpost describes what you are looking for: To clear your SSL session state in Firefox choose History -> Clear Recent History... and then select "Active Logins" and click "Clear Now". Then the next time you connect to your SSL server Firefox will prompt for which certificate to use. 来源: https://stackoverflow.com/questions/24040662/how-do-you

Java X509 Certificate parsing and validating

南楼画角 提交于 2019-11-30 06:23:34
问题 I'm trying to process X509 certificates in several steps and running into a couple of problems. I'm new to JCE so I not completely up to date on everything yet. We want to be able to parse several different X509 certificates based on different encodings (PEM, DER and PCKS7). I've exported the same certificate from https://belgium.be in PEM and PCKS7 format using FireFox (certificate including chain). I've left couple lines out that are not needed for the questions public List<X509Certificate>

How does Android's app/signature verification work?

我的梦境 提交于 2019-11-30 04:01:25
I want to preface this question with two things so I can narrow down where my actual question is: a) I've done software dev before, though never for android b) I'm familiar with PKI and encryptions and hashing and digital signatures and blah blah blah That being said I'm having trouble tracking down more information about where and how Android verifies app creators. I've heard a lot of different information so I'm trying to synthesize to get a better idea of the workflow. I know that every app developer gets their own private/public key pair and they sign their apps by hashing the APK (with
