keys are smaller – this, for instance, means that it’s easier to transfer and to copy/paste them.

collision resilience – this means that it’s more resilient against hash-function collision attacks (types of attacks where large numbers of keys are generated with the hope of getting two different keys have matching hashes).

Why ed25519 Key is a Good IdeaĬompared to the most common type of SSH key – RSA – ed25519 brings a number of cool improvements: Similarly, not all the software solutions are supporting ed25519 right now – but SSH implementations in most modern Operating Systems certainly support it. Still, people are such creatures of habits that many IT professionals daily using SSH/SCP haven’t even heard of this key type. I say relatively, because ed25519 is supported by OpenSSH for about 5 years now – so it wouldn’t be considered a cutting edge.

Here is the video with steps: What is ed25519?Įd25519 is a relatively new cryptography solution implementing Edwards-curve Digital Signature Algorithm (EdDSA). Today I decided to setup a new SSH keypair. Replace the with the IP address or FQDN (Fully Qualified Domain Name) of the remote Linux device you would like to copy the public key to.I’m hoping to reinstall my MacBook Pro 15” 2017 with a fresh macOS Catalina sometime soon, and part of preparations is testing my install methods (hello, brew!) and configuration files migration. Next, we use the below PowerShell one-line command to copy the contents of the id_rsa.pub public key to a remote Linux device.
