How to convert Byte array to PrivateKey or PublicKey type?

由 大憨熊 提交于 2019-11-27 00:36:55
问题 I am using RSA algorithm to generate public and private key final KeyPairGenerator keyGen = KeyPairGenerator.getInstance(ALGORITHM); keyGen.initialize(1024); final KeyPair key = keyGen.generateKeyPair(); final PrivateKey privateKey=key.getPrivate(); final PublicKey publickey=key.getPublic(); after that these keys are encoded using Base64 encoder and save it into database. How to convert this encoded String to Private and Public Key Type in java is to decrypt file. when decoding this String

Github: readonly access to a private repo

由 假装没事ソ 提交于 2019-11-27 00:19:23
问题 I am developing some private projects on Github, and I would like to add nightly cronjobs to my deployments servers to pull the latest version from github. I am currently doing this by generating keypairs on every deployment server and adding the public key to the github project as 'Deployment key'. However, I recently found out that these deployment keys actually do have write access to the project. Hence, every of the server administrators could potentially start editing. Furthermore I can

What is the difference between a cer, pvk, and pfx file?

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? erickson 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. Windows uses .pfx for a PKCS #12 file. This file can contain a variety of cryptographic information,

How to sign string with private key

由 隐身守侯 提交于 2019-11-26 19:25:51
问题 How can I get the signature of a string using SHA1withRSA if I already have the Private Key as byte[] or String ? 回答1: I guess what you say is you know the key pair before hand and want to sign/verify with that. Please see the following code. import java.security.KeyPair; import java.security.KeyPairGenerator; import java.security.NoSuchAlgorithmException; import java.security.Signature; import sun.misc.BASE64Encoder; public class MainClass { public static void main(String[] args) throws

问题 I added the public ssh key to the authorized_keys file. ssh localhost should log me in without asking for the password. I did that and tried typing ssh localhost , but it still asks me to type in the password. Is there any other setting that I have to go through to make it work? I have followed instruction for changing permissions: Below is the result if I do ssh -v localhost debug1: Reading configuration data /home/john/.ssh/config debug1: Reading configuration data /etc/ssh/ssh_config

Converting Strings to encryption keys and vice versa java

由 耗尽温柔 提交于 2019-11-26 15:41:34
问题 I'm currently working on a way to convert keys into strings and vice versa. It works for the public key conversions, and converts a private key into a String. For some reason the same code won't convert a String back into a private key, which I just can't figure out. The converter code is: import java.security.KeyFactory; import java.security.PrivateKey; import java.security.PublicKey; import java.security.spec.X509EncodedKeySpec; import sun.misc.BASE64Decoder; import sun.misc.BASE64Encoder;

Encrypt in Javascript, decrypt in PHP, using public-key cryptography

由 无人久伴 提交于 2019-11-26 15:14:35
问题 I'd like to encrypt in JavaScript, decrypt in PHP, using public-key cryptography. I've been trying to find libraries that can accomplish this, but am having issues. I am currently looking at openpgpjs, but I need support in all browsers, and even the test page has errrors on the only listed as supported browser (Google Chrome). Notes about the final goal: The TCP connection is already protected by SSL. The main purpose of this layer of protection is defending against intentional or

Getting the PublicKeyToken of .Net assemblies

由 ∥☆過路亽．° 提交于 2019-11-26 15:06:39
问题 What is the simplest way to find the Public-Key-Token of an assembly? The simplest way I can think of would be a simple right-click, get public key, but this functionality isn't there, maybe there is a Visual Studio Extension for that? I'm using Visual Studio 2010, if an extension is available. 回答1: Open a command prompt and type one of the following lines according to your Visual Studio version and Operating System Architecture : VS 2008 on 32bit Windows : "%ProgramFiles%\Microsoft SDKs
