Cashier is a SSH Certificate Authority (CA) that enables a more secure and manageable way to authenticate SSH connections. It facilitates the issuance of short-lived, digitally signed certificates, replacing traditional SSH keys. By signing public keys, Cashier provides enhanced control over access, allows for revocation, and simplifies user management compared to key-based authentication.
Cashier offers a streamlined authentication process by eliminating the need to distribute individual SSH keys to each machine. It enables certificate revocation, a crucial security feature often missing with SSH keys. The project is designed with flexibility in mind, supporting various storage options for sensitive data like signing keys and secrets, improving overall security and administrative ease.
- Certificate Issuance: Generates and signs SSH certificates for authentication.
- Revocation: Allows for the revocation of compromised or expired certificates.
- User Management: Enables granular control over who can access resources via SSH.
- Configuration Flexibility: Supports various configuration options for server settings, database integration, and authentication providers.
- Authentication Providers: Integrates with various authentication providers like Google and GitHub.
Cashier is an active project with ongoing development and maintenance. Recent commits indicate continued improvements and bug fixes. The documentation is generally comprehensive, although some areas could benefit from further clarification. A visible community presence supports ongoing development.
Cashier is beneficial for organizations seeking a more secure and manageable way to manage SSH access. It addresses the limitations of traditional SSH keys by providing certificate-based authentication with features like revocation, which improves security and reduces administrative overhead. It's ideal for scenarios requiring centralized SSH access control and streamlined user onboarding.
