Export secret key from jck key store

由 主宰稳场 提交于 2019-12-10 21:19:06
问题 We have a jck keystore (jceks) format containing a secret key. It was generated using keytool command keytool -genseckey -alias mykey -keyalg AES -keysize 256 -storetype jceks -keystore mykeystore.jks We need to share this with another application and they seem to have limitations in working with jck store. They are asking for the key to be exported and supplied to them. We tried a few tools, but are not able to export the secret key. Is there a command or workaround to achieve this ? 回答1:

问题 I'm want to encrypt and decrypt files from SD-card using AES. In order to do it we always need a seed (usually a string which is inserted by user as a password): public static byte[] generateKey(String password) throws Exception{ byte[] keyStart = password.getBytes("UTF-8"); KeyGenerator kgen = KeyGenerator.getInstance("AES"); SecureRandom sr = SecureRandom.getInstance("SHA1PRNG", "Crypto"); sr.setSeed(keyStart); kgen.init(128, sr); SecretKey skey = kgen.generateKey(); return skey.getEncoded(

Keeping a secret key secret with Amazon Web Services

问题 I'm playing around with using amazon web services in my personal project. I've grabbed their AWS SDK for .NET and I'm using that, but I'm a little confused. Access to the web service (in this case, SimpleDB, though I don't think that's really material to the question) is authorized via a private/public key pair. The AWS SDK for .NET API used to create a client object requires the private key: AWSClientFactory.CreateAmazonSimpleDBClient(publicKey, privateKey); This is a client application, so

问题 Microservices and Cloud is a thing. Everyone is talking and writing about. Personally i am thinking a lot about this topics: How this can be used to benefit from? What are possible challenges? How can this speedup the daily development? And how to manage all things? One question that bothers me since a few days is "How to manage secrets in a Microservice / Cloud environment?". Imagine a company with 150 software engineers and various teams with various products. Every team is creating a
