Although this depends on the KeyStore type, generally, you can store multiple private keys and certificates in a single store. Which key and certificate combination is used for a Java-based server will depend on how the application was implemented. A number of applications let you select a given certificate using the alias name. The key … Read more
You can extract a private key from a keystore with Java6 and OpenSSL. This all depends on the fact that both Java and OpenSSL support PKCS#12-formatted keystores. To do the extraction, you first use keytool to convert to the standard format. Make sure you use the same password for both files (private key password, not … Read more
You can load trusted key stores dynamically at runtime. // load your key store as a stream and initialize a KeyStore InputStream trustStream = … KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType()); // if your store is password protected then declare it (it can be null however) char[] trustPassword = … // load the stream to your store … Read more
If you lost your keystore then there is no way that you can update the app in play sore( it will cause a signature error )! The only way is that you can create an app with a new package name upload it to store and remove the old app.
I had to do something similar a while back. I had a certificate file and I had to figure out a way to load it in and use it for an SSL connection. Hopefully what I did will help you out. First I had to create a trust manager: public class MyX509TrustManager implements X509TrustManager { … Read more
I found my answer on the Android Issue Tracker; from what I understand the unrestricted PublicKey, created to work around another known issue, becomes incompatible with the current Cipher. The work-around for this is to specify an OAEPParameterSpec when the Cipher is initialized: OAEPParameterSpec spec = new OAEPParameterSpec( “SHA-256”, “MGF1”, MGF1ParameterSpec.SHA1, PSource.PSpecified.DEFAULT); mCipher.init(opmode, unrestricted, spec);
It turned out that a KeyStore instance still has to be built, but it can be done in memory (starting with PEM files as input), without using an intermediate keystore file build with keytool. To build that in-memory KeyStore, code like the following may be used: private static final String TEMPORARY_KEY_PASSWORD = “changeit”; private KeyStore … Read more
Yes. In Unix like os the debug key is located by default in ~/.android/debug.keystore You also can choose a custom one from eclipse like in the following screenshot:
I followed This link. 1.Generate keystore(At server): keytool -genkey -alias bmc -keyalg RSA -keystore KeyStore.jks -keysize 2048 2.Generate new ca-cert and ca-key: openssl req -new -x509 -keyout ca-key -out ca-cert 3.Extracting cert/creating cert sign req(csr): keytool -keystore KeyStore.jks -alias bmc -certreq -file cert-file 4.Sign the “cert-file” and cert-signed wil be the new cert: openssl x509 … Read more
I may have had the same problem. I never did figure out why it was failing (though I wonder if it was because the keystore password was shorter than 6 digits), but I was able to copy my key into a new keystore, which I then renamed to replace the old one, and it mysteriously … Read more
