Generate SSH keys for Windows 7 and BitBucket

• Start Git Bash
• Check files in the .ssh folder (ls -al ~/.ssh)
• Generate Keys (ssh-keygen -t rsa -b 4096 -C "your_email@example.com")
• When prompted to "Enter file in which to save the key" specify the filename. Do not include the full path. (Unable to resolve open c/Users/userid/.ssh/<filename> failed: No such file or directory)
• The files get saved in the c/Users/userid directory.
• Copy them to the c/Users/userid/.ssh/ directory
• Ensure ssh-agent is enabled : eval $(ssh-agent -s)
• Add your SSH key to the ssh-agent: ssh-add ~/.ssh/<filename>
• Login to BitBucket and goto Manage Account
• Click on SSH Keys in the left menu.
• Copy the SSH key to your clipboard: clip < ~/.ssh/<filename>.pub (Git Bash)
• In BitBucket->SSH Keys, click on Add Key
• Specify a label and paste the copied key contents in the textbox for key
• Test Connection (ssh -T git@github.com)
