PuTTY Key Generator
PuTTY Key Generator (PuTTYgen) is a free, open-source key generation utility included with the PuTTY SSH client suite for Windows. It is used to create, manage, and convert public-private key pairs for secure authentication in protocols like SSH, primarily for connecting to remote servers without passwords. The tool supports various key types, including RSA, DSA, ECDSA, and Ed25519, and can export keys in formats compatible with different systems.
Developers should use PuTTY Key Generator when working with SSH connections on Windows, especially for automating secure logins to Linux servers, cloud instances, or network devices. It is essential for setting up key-based authentication, which enhances security by eliminating password vulnerabilities and streamlining deployments in DevOps workflows, such as with CI/CD pipelines or remote server management.
