Loading raw 64-byte long ECDSA public key in Java

与世无争的帅哥 提交于 2019-11-26 14:23:23
问题 I have a raw (r,s) format ECDSA NIST P-256 public key. It seems that there is no simple way to load it into an object that implements java.security.interfaces.ECPublicKey. What is the cleanest way to load a 64 byte public key so that it can be used to check signatures? 回答1: Java 7 is required for the EC functionality and Java 8 for the Base 64 encoder / decoder, no additional libraries - just plain Java. Note that this will actually display the public key as a named curve when printed out,

RSA: Get exponent and modulus given a public key

巧了我就是萌 提交于 2019-11-26 12:50:57
问题 I need to encrypt some data using RSA in JavaScript. All of the libraries around ask for an exponent and a modulus, yet I get a single public.key file from my opponent. How do you retrieve the public exponent and modulus part from an RSA file? 回答1: It depends on the tools you can use. I doubt there is a JavaScript too that could do it directly within the browser. It also depends if it's a one-off (always the same key) or whether you need to script it. Command-line / OpenSSL If you want to use

Raghav RV 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:add To clear all your previous keys do : heroku keys:clear To display all your existing keys do :

Git SSH authentication

蓝咒 提交于 2019-11-26 09:01:40
I have Debian, Fisheye and Git on my server. My git repos are managed by Fisheye. There is no authentication at the Fisheye part. All authentication procedures are managed by git. I would like to use SSH authentication, so that I do not need to provide username and password as I push my changes to the server. I know how to create an rsa key, but where do I copy my public key at the server? VonC The key part of the article " Git on the Server - Setting Up the Server " is: you need to add some developer SSH public keys to the ~/.ssh/authorized_keys file for that user. Let’s assume you’ve

问题 How can I transform between the two styles of public key format, one format is: -----BEGIN PUBLIC KEY----- ... -----END PUBLIC KEY----- the other format is: -----BEGIN RSA PUBLIC KEY----- ... -----END RSA PUBLIC KEY----- for example I generated id_rsa/id_rsa.pub pair using ssh-keygen command, I calculated the public key from id_rsa using: openssl rsa -in id_rsa -pubout -out pub2 then again I calculated the public key from id_rsa.pub using : ssh-keygen -f id_rsa.pub -e -m pem > pub1 the

问题 How do I setup Public-Key Authentication for SSH? 回答1: If you have SSH installed, you should be able to run.. ssh-keygen Then go through the steps, you'll have two files, id_rsa and id_rsa.pub (the first is your private key, the second is your public key - the one you copy to remote machines) Then, connect to the remote machine you want to login to, to the file ~/.ssh/authorized_keys add the contents of your that id_rsa.pub file. Oh, and chmod 600 all the id_rsa* files (both locally and
