NoteVMs created using SSH keys are by default configured with passwords disabled, which greatly increases the difficulty of brute-force guessing attacks.For more background and examples, see.For additional ways to generate and use SSH keys on a Windows computer, see. Other key formats such as ED25519 and ECDSA are not supported. 
You can complete these steps with the Azure Cloud Shell, a macOS or Linux host, the Windows Subsystem for Linux, and other tools that support OpenSSH. Supported SSH key formatsAzure currently supports SSH protocol 2 (SSH-2) RSA public-private key pairs with a minimum length of 2048 bits.
CNG is an encryption API that you can use to create encryption security software for encryption key management, cryptography and data security, and cryptography and network security. Cryptography API: Next Generation - Win32 apps Microsoft Docs. Provides a Cryptography Next Generation (CNG) implementation of the Elliptic Curve Diffie-Hellman (ECDH) algorithm. This class is used to perform cryptographic operations. The following example shows how to use the ECDiffieHellmanCng class to establish a key exchange and how to use that key to encrypt a message that. Alice and Bob create.

Purpose
Cryptography API: Next Generation (CNG) is the long-term replacement for the CryptoAPI. CNG is designed to be extensible at many levels and cryptography agnostic in behavior.
Developer audience
What Is Public Key Cryptography
CNG is intended for use by developers of applications that will enable users to create and exchange documents and other data in a secure environment, especially over nonsecure media such as the Internet. Developers should be familiar with the C and C++ programming languages and the Windows-based programming environment. Although not required, an understanding of cryptography or security-related subjects is advised.
Key Exchange And Generation In Cryptography 2016
If you are developing a CNG cryptographic algorithm provider or key storage provider, you must download the Cryptographic Provider Development Kit from Microsoft.
Run-time requirements
CNG is supported beginning with Windows Server 2008 and Windows Vista. For information about run-time requirements for a particular programming element, see the Requirements section of the reference page for that element. Active boot disk 11 key generator.
