With Ed25519 SSH key support for Linux virtual machines (VMs), customers get better security and performance with a smaller key size. Previously, customers only had the option of using RSA encryption for SSH connections to their Linux VMs on Azure. Now customers can choose between RSA and ED25519 based SSH keys.
Azure now allows the creation of ED25519 SSH key pairs directly within the Azure Portal for a simplified key management process. Additionally, Azure CLI and PowerShell support this feature. While RSA remains the default key type, users can also apply ED25519 SSH keys to their Linux VMs, enhancing security and deployment efficiency on Azure.
