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);
By default, Jenkins launches Execute Shell script with set -x. This causes all commands to be echoed You can type set +x before any command to temporary override that behavior. Of course you will need set -x to start showing them again. You can override this behaviour for the whole script by putting the following … Read more
I’m not surprised this didn’t gain any traction, but here is what I did for anyone who stumbles onto this post. As I said, all of my files were backed up. I restored the android.jks file from an older backup. Then, I opened a Terminal window and typed in the following: keytool -storepasswd -new [insert … Read more
I started with the premise that I could use AndroidKeyStore to secure arbitrary blobs of data, and call them “keys”. However, the deeper I delved into this, the clearer it became that the KeyStore API is deeply entangled with Security-related objects: Certificates, KeySpecs, Providers, etc. It’s not designed to store arbitrary data, and I don’t … Read more
keytool comes with the Java SDK. You should find it in the directory that contains javac, etc.
You can use that keystore for any number of applications. No need to generate a new keystore.
Use this command, (go to java < jdk < bin path in cmd prompt) $ jarsigner -verify -verbose -certs my_application.apk If you see “CN=Android Debug”, this means the .apk was signed with the debug key generated by the Android SDK (means it is unsigned), otherwise you will find something for CN. For more details see: … Read more
With inspiration from @Andy Developer, I could display the map after my app was uploaded to Google Play. These were the steps: Upload your app to Google Play (signed APK file) After the app has been submitted and approved, select your app from Google Play Console Go to Development Tools -> Release management -> App … Read more
First, unzip the APK and extract the file /META-INF/ANDROID_.RSA (this file may also be CERT.RSA, but there should only be one .RSA file). Then issue this command: keytool -printcert -file ANDROID_.RSA You will get certificate fingerprints like this: MD5: B3:4F:BE:07:AA:78:24:DC:CA:92:36:FF:AE:8C:17:DB SHA1: 16:59:E7:E3:0C:AA:7A:0D:F2:0D:05:20:12:A8:85:0B:32:C5:4F:68 Signature algorithm name: SHA1withRSA Then use the keytool again to print out all … Read more
In order to generate key hash you need to follow some easy steps. 1) Download Openssl from: here. 2) Make a openssl folder in C drive 3) Extract Zip files into this openssl folder created in C Drive. 4) Copy the File debug.keystore from .android folder in my case (C:\Users\SYSTEM.android) and paste into JDK bin … Read more
