Jul 20, 2019 Welcome to my first official guide on Dev.to. Today I want to explain how you can setup SSH and Git on your Windows 10 computer. Note: This is not about 100% securing your keys but about how to generate keys for use with GitHub.
A utility for deterministically generating ssh keypairs. PROOF OF CONCEPT ONLY.
Nov 24, 2015 GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together. Sign up Using SSH public-key authentication to connect to a remote system. Adding your SSH key to the ssh-agent. Before adding a new SSH key to the ssh-agent to manage your keys, you should have checked for existing SSH keys and generated a new SSH key. When adding your SSH key to the agent, use the default macOS ssh-add command, and not an application installed by macports, homebrew, or some other external source.
Each keypair is generated by hashing together a 'seed' or 'master key' (shouldbe at least 32 bytes, randomly generated, and kept secret) and a unique'handle' (using the same handle will result in the same keypair, but the handledoes not need to be kept secret); the resulting SHA256 hash is used as theinput for generating an Ed25519 keypair.
This allows the creation of a large number of unique keypairs without having toactually manage the keypairs individually. This allows for, say, using adifferent keypair for every host you need to log into, thus preventing someonefrom correlating different user accounts on different hosts by the public keysin authorized_keys.
This proof of concept implementation just generates one keypair at a time;ideally the keypairs would be generated on demand, perhaps by an SSH agentimplementation (the key generation step should only take a few milliseconds).
Note that while Ed25519 allows for using any 32-byte input to generate akeypair, making this implementation trivial, implementing a similar scheme forother key types is probably possible in some cases (eg. ECDSA), and infeasiblein others (DSA/RSA, probably).
You will need ghc and cabal, as well as the libsodium development files; onDebian/Ubuntu, the ghc and libsodium-dev packages are what you need.
./seed is the master key, HIMOM is the key handle, and ./id_ed25519 isthe output file into which the private key will be placed. ssh-keygen is theninvoked to print the public key out.
There are three modes available:
The example above is looking for a set of Markdown files, so in order to let Gridsome understand the content of the files, you must install @gridsome/transformer-remark as a dev dependency in your project. Gridsome will automatically transform the files for you as long as a transformer that supports your files is found in your package.json. Options path. Gridsome-plugin-rss Generate an RSS feed from your Gridsome data store Read more about gridsome-plugin-rss @gridsome/source-contentful Contentful source for Gridsome Read more about @gridsome/source-contentful. Say hello to Gridsome ??? A new static site generator baby is born. It's highly inspired by Gatsby.js (React based) but built on top of Vue.js. We have been working on it for a year and will have a beta ready soon. You can expect this baby to grow up fast! October 2018.
The first step you need to do is to create a folder called gridsome-plugin-remark-codesandbox which follows the convention of other Gridsome Remark plugins. From there you will create a new package.json by running the command npm init. Gridsome source filesystem, Jan 31, 2019 Let's take a look at a few more features of Gridsome. How Gridsome Works. If you were just going to have a plain static site you wouldn't really need something like Gridsome. Where Gridsome really shines is its ability to use multiple data source and combine them into a single GraphQL data layer.
raw: Use the seed as is; must be at least 32bytes long, and must have at least that much entropy in it to avoidweaker-than-expected keys.
generate: Same as raw, except that a new seed will be generated using anappropriate platform-specific mechanism. The program will try not tooverwrite an existing seed file.
key: Use an existing Ed25519 SSH private key. Only the seed of the key willbe used, rather than the whole key file data, so changes in the metadata willnot affect generation.
Hi there! This post will be pretty straightforward and will cover Windows, Mac, and Linux, so if you don’t know how to do it already, read on.
Windows
Just follow these 5 steps:
Go to this address, and download Git for Windows, after the download install it with default settings
Open Git Bash that you just installed (Start->All Programs->Git->Git Bash)
Type in the following: ssh-keygen -t rsa (when prompted, enter password, key name can stay the same)
Open file your_home_directory/.ssh/id_rsa.pub with your favorite text editor, and copy contents to your Git repository’s keys field (GitHub, beanstalk, or any other repository provider), under your account.
Be sure that you don’t copy any whitespace while copying public key’s content (id_rsa.pub)
Note: your_home_directory is either C:Usersyour_username (on Windows Vista / 7 / 8 / 10), or C:Documents and Settingsyour_username (on Windows XP)
Mac
Follow these 5 steps:
Start the terminal
Navigate to your home directory by typing: cd ~/
Execute the following command: ssh-keygen -t rsa (when prompted, enter password, key name can stay the same)
Open the file you’ve just created ~/.ssh/id_rsa.pub with your favorite text editor, and copy contents to your Git repository’s keys field (GitHub, beanstalk, or any other repository provider), under your account.
Be sure that you don’t copy any whitespace while copying public key’s content (id_rsa.pub)
Linux (Ubuntu)
Follow these 5 steps:
Open console
cd ~
ssh-keygen -t rsa (when prompted, enter password, key name can stay the same)
open file /home/your_username/.ssh/id_rsa.pub with your favorite text editor, and copy contents to your Git repository’s keys field (GitHub, beanstalk, or any other repository provider), under your account.
Be sure that you don’t copy any whitespace while copying public key’s content (id_rsa.pub)
Additional info
When you create private/public SSH keys on your machine (that’s what you did in the above steps), it’s not enough. You need to give your public key to the repository in order to pair the Git server with your local machine (that’d be steps 4. and 5. above).
Most of the popular repositories will give you web interface access to the application, and here’s how it looks like on Github: After this step, you’re ready to start using Git.
Conclusion
I hope this wasn’t too complicated to follow, and also I hope it was helpful to someone!
