keystore

问题 I was given a keystore file along with an username and password and I need to sign the updated application. However, I am getting "keytool error: java.io.IOException: Invalid keystore format" when trying to list the contents of the file, trying to create a new key in the keystore, etc. I have looked at the similar posts, but none of them helped me. I am looking forward to hearing a solution. Thanks in advance 回答1: It turned out that the file was an RAR archive file that contained the actual

问题 I use a keystore (BKS format) in my android app to store public private keypairs. The app was used over a long time and had 10+ public private key pairs. All of a sudden, one of the app's major functionality stopped working. Root cause was found out to be the following: Only one public private keypair is remaining in the BKS file. All other keypairs are lost. I verified in the code that KeyStore.deleteEntry(alias) is not called anywhere in the app. The only place where I could find if

问题 I have a valid P12 file. I need to instantiate an X509certificate object, so that I can use it as a client side certificate. I realize that there is already a similar question answered here, How to instantiate javax.security.X509Certficate object from a p12 certificate (contains certificate + private key) But in Blackberry, the getInstance(String) method is not available for KeyStore. It's available for DeviceKeyStore and TrustedKeyStore. But we can't pass the "PKCS12" parameter to the

问题 I have a SSL certificate for my application and I want to use it for digitally signing PDF files using iText. The extension of the certificate is .cer and is provided by a certificate signing authority (CA). The problem is that I am not able to convert this .cer certificate into java keystore which is required while signing the PDF using itext library. The code that I have is: This code obviously throws Invalid keystore format IOException. KeyStore ks = KeyStore.getInstance(KeyStore

问题 I found tutorial which describes how create and use keystore for https connection.

问题 I'm trying to implement ECDH in Android using a private generated by Android KeyStore Provider. public byte[] ecdh(PublicKey otherPubKey) throws Exception { try { ECPublicKey ecPubKey = (ECPublicKey) otherPubKey; KeyAgreement keyAgreement = KeyAgreement.getInstance("ECDH"); PrivateKey pk = (PrivateKey) LoadPrivateKey("Backend"); keyAgreement.init(pk); keyAgreement.doPhase(ecPubKey, true); return (keyAgreement.generateSecret()); } catch (Exception e) { Log.e("failure", e.toString()); return

问题 We have lost our original keystore used to generate the CSR during a server failure. We have a backup of the private key (.key file) and the original CSR (.csr file). Is it possible to reconstruct the keystore with those? Since all the instructions for creating the certificate chains require the original keystore. This is for use with Tomcat 7.0.27. Thanks 回答1: Yes, that should be possible. But in addition to the private key you will also need the certificate (not csr) that was returned by
