PuTTYgen 0.7.4

PuTTYgen is a versatile and user-friendly software that allows you to generate SSH keys effortlessly. It is an essential component of the popular networking client PuTTY, but can also be downloaded separately for standalone use.

With PuTTYgen, you have the option to either create a new key pair or load an existing one. When generating a new key, you can choose from various types such as RSA, DSA, ECDSA, and Ed25519, each designed to ensure secure data transmission and digital signatures.

Once you have selected the desired key type and strength, simply click the Generate button and wait for PuTTYgen to generate the key. You can then add a comment and passphrase for added security. The private key can be saved to your disk, while the public key can be copied to your server through various methods.

One of the convenient features of PuTTYgen is the ability to load existing key pairs, allowing you to modify the passphrase and comment. Additionally, you can make multiple copies of the public key for different purposes.

It is important to note that PuTTYgen supports key types for both SSH-2 and SSH-1 protocols. While SSH-1 only supports RSA keys, SSH-2 offers a wider range of options including DSA, ECDSA, and Ed25519.

Overall, PuTTYgen simplifies the process of generating SSH keys and provides a user-friendly interface for managing key pairs. Whether you are a PuTTY user or simply in need of a reliable key generator, PuTTYgen is a valuable tool to have.
