public-key

问题 I've researched a bit about how to achieve what I said in the question and found several APIs but most of them look very complicated and since I'm just a noobie in this area I just want a simple method like: public String Encrypt(String message, PublicKey publicKey) Don't know if this can be done? If not then please someone enlighten me another way to achieve this :) Thank you. UPDATE: So far I have only seen that all of the library for OpenPGP encryption require both the public key and

问题 From Android In App Billing version 3 (TrivialDrive)sample application coming with sdk MainActivity.java /* base64EncodedPublicKey should be YOUR APPLICATION'S PUBLIC KEY * (that you got from the Google Play developer console). This is not your * developer public key, it's the *app-specific* public key. * * Instead of just storing the entire literal string here embedded in the * program, construct the key at runtime from pieces or * use bit manipulation (for example, XOR with some other

问题 I need to integrate my iPhone app with a system, and they require to encrypt data by a given public key, there are 3 files in 3 different format .xml .der and .pem, I have researched and found some articles about getting SecKeyRef from DER/PEM, but they are always return nil. Below is my code: NSString *pkFilePath = [[NSBundle mainBundle] pathForResource:@"PKFile" ofType:@"der"]; NSData *pkData = [NSData dataWithContentsOfFile:pkFilePath]; SecCertificateRef cert; cert =

问题 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? 回答1: 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

问题 I have a strange problem with cloning a git repository from an amazon ec2 server. It works without any problems on one of my computers running ubuntu 12.04, while on another one using 12.10 it gives me an error: ssh: Could not resolve hostname ec2server: Name or service not known fatal: The remote end hung up unexpectedly It's like it is not recognizing my config file. I use the following git command to clone : sudo git clone ec2server:/var/www/project.git or sudo git clone ec2xxx.compute-1

问题 What is the difference between a cer, pvk, and pfx file? Also, which files do I keep and which am I expected to give to my counter-parties? 回答1: Windows uses .cer extension for an X.509 certificate. These can be in "binary" (ASN.1 DER), or it can be encoded with Base-64 and have a header and footer applied (PEM); Windows will recognize either. To verify the integrity of a certificate, you have to check its signature using the issuer's public key... which is, in turn, another certificate.

问题 I'm attempting to deploy my code to heroku with the following command line: git push heroku master but get the following error: Permission denied (publickey). fatal: The remote end hung up unexpectedly I have already uploaded my public SSH key, but it still comes up with this error. 回答1: You have to upload your public key to Heroku: heroku keys:add ~/.ssh/id_rsa.pub If you don't have a public key, Heroku will prompt you to add one automatically which works seamlessly. Just use: heroku keys

问题 I want to protect my RSA private key with a password (who wouldn't) but the following C# fails: SecureString pw = new SecureString(); pw.AppendChar('x'); CspParameters prms = new CspParameters(); prms.KeyPassword = pw; RSACryptoServiceProvider crypto = new RSACryptoServiceProvider(prms); byte[] encrypted = crypto.Encrypt(Encoding.ASCII.GetBytes("encryptme"), true); ...with the CryptographicException: "Invalid type specified". If I take the KeyPassword assignment out it works fine. What am I,
