SSH Key Tools

Automated SSH key generation and management for multiple git repositories across any provider — GitHub, GitLab, Bitbucket, or custom SSH hosts.
Each repo gets its own dedicated SSH key without overwriting others.

Install

git clone https://github.com/tieutantan/SSH-Key-Tools.git

Usage

# Interactive mode (menu)
./ssh-tools.sh

# Generate key for a GitHub repository
./ssh-tools.sh git@github.com:user/repo.git

# Generate key for a GitLab project
./ssh-tools.sh git@gitlab.com:group/project.git

# Generate keys for multiple providers at once
./ssh-tools.sh git@github.com:user/repo.git git@bitbucket.org:team/project.git

# List all existing SSH keys and clone commands
./ssh-tools.sh --list

# Remove key for a repository
./ssh-tools.sh --remove <repo_name>

# Show help
./ssh-tools.sh --help

The provider (github, gitlab, bitbucket, etc.) is auto-detected from the URL.

Key naming convention

Component	Format	Example
Key file	~/.ssh/id_ed25519_<repo_name>	~/.ssh/id_ed25519_my-app
Host alias	<provider>-<repo_name>	github-my-app, gitlab-my-app

SSH Config

The script automatically adds a host alias to ~/.ssh/config, without overwriting the original host entry:

Host github-my-app
    HostName github.com
    User git
    IdentityFile ~/.ssh/id_ed25519_my-app
    AddKeysToAgent yes
    IdentitiesOnly yes

Clone command using the host alias:

git clone git@github-my-app:user/my-app.git

Add Deploy Key

After running the script, copy the displayed public key and add it to your git provider:

Repository → Settings → Deploy keys → Add deploy key
