key-pair

I try to get sha384 with ECDSA keys. I follow up with this article: https://digitalleaves.com/blog/2015/10/asymmetric-cryptography-in-swift/?replytocom=52690#respond but I change RSA to EC, of course. and keys are generated, but encryptMessageWithPublicKey doesn't work :( Variable "status" in method: encryptMessageWithPublicKey return -50 ... Here is my code: import UIKit import Security private let _singletonInstance = AsymmetricCryptoManager() private let kAsymmetricCryptoManagerApplicationTag = "com.AsymmetricCrypto.keypair" private let kAsymmetricCryptoManagerKeyType = kSecAttrKeyTypeEC/

I have app which uses Fingerprint and 4 digit pin (which can be set by user in application settings, this is not system pin/pattern/password) authorization. With Fingerprint everything is fine, I have problem with pin. What I'm trying to do is: Let user set pin from application settings Generate Keypair in keystore for some alias protected by entered pin (so that private key can not be accessed without this pin) Send public key to server for future signature verification Get user token from server and store it in local storage Then during Authorization: Request user to enter the pin Retrieve

I am creating a method to generate a key pair.I need to secure the private key with a password.My code works fine except that it gives me java.security.InvalidKeyException: Illegal key size or default parameters error. When i searched the cause of the error,it says to replace the policy jars in jre/lib/security folder with unlimited access files for the same.I have jdk7 installed and i downloaded the policy files and replaced that the lib/security folder.But the error remains the same.Here is the code. // generate a key pair KeyPairGenerator kpg = KeyPairGenerator.getInstance("RSA"); kpg

I have created my own EBS AMI, shared it with another AWS account, launched NEW instance based on this image with NEW key-pair and now when I am trying to connect to this new instance I am getting error: "Server Refused our key". This is what I did (step by step): Configured new CentOS 6.3 server in my personal account (with my personal key-pair) Created EBS AMI image of that server Shared this image with my client's account Launched new instance in my clients account based on this shared image + new key-pair New launched instance doesnt want to take new key-pair. After some testing I figure

I use JSch with private key to FTP file jsch.addIdentity(privatekeyfile); Session session = jsch.getSession( "user", "domain.com" ,22); session.setConfig("StrictHostKeyChecking", "no"); Line 3 is in question. Without this line, JSch does not work. My question is: Will line 3 make SFTP transfer insecure? Disabling the StrictHostKeyChecking option will make the connection less secure than having the option enabled, because it will let you connect to remote servers without verifying their SSH host keys. If the option is enabled, you will only be able to connect to servers which keys are known to
