Steps to create SSH key from git bash

Generating an SSH key in OpenSSH involves a few simple steps. Here’s how you can do it: 1. Open a Terminal If you're on Linux or macOS, you can use the built-in terminal. On Windows, you can use the Command Prompt, PowerShell, or Git Bash if you have Git installed. 2. Generate the SSH Key Pair Run the following command: bash Copy code ssh-keygen -t rsa -b 4096 -C "your_email@example.com" Here’s what each option means: -t rsa : Specifies the type of key to create, in this case, RSA. -b 4096 : Specifies the number of bits in the key, 4096 bits is a good choice for strong encryption. -C "your_email@example.com" : Adds a label to the key, usually your email address. 3. Choose a File Location After running the above command, you'll be prompted to choose a location to save the key. By default, it will be saved in ~/.ssh/id_rsa (on Linux or macOS) or in C:\Users\YourUserName\.ssh\id_rsa (on Windows). Press Enter to accept the default location, or specify a diff...
