About:
SignMyKey is an automated SSH Certificate Authority that simplifies SSH key management by issuing short-lived certificates instead of static keys. It provides centralized control over SSH access, integrates with existing identity providers, and eliminates the need to distribute or revoke individual public keys. This approach enhances security by reducing the attack surface and ensuring access is automatically revoked when certificates expire.
Key Features:
  • Automated SSH certificate issuance
  • Integration with identity providers (e.g., LDAP, OAuth)
  • Short-lived certificates for enhanced security
  • Centralized access control and auditing
  • Easy deployment and configuration
Use Cases:
  • Securing SSH access in enterprise environments
  • Managing developer access to servers and infrastructure
  • Replacing static SSH keys with certificate-based authentication
Alternatives:
  • HashiCorp Vault – Vault offers broader secrets management including SSH CA, but SignMyKey is specialized and simpler for SSH-only use cases.
  • Smallstep – Smallstep provides a more general certificate authority for various protocols, while SignMyKey focuses specifically on SSH automation.
