Openssl req -x509 -newkey rsa:2048 -keyout key.pem -out cert.pem -days XXX req PKCS#10 certificate request and certificate generating utility.-x509 this option outputs a self signed certificate instead of a certificate request. This is typically used to generate a test certificate or a self signed root CA.-newkey arg. Azure currently supports SSH protocol 2 (SSH-2) RSA public-private key pairs with a minimum length of 2048 bits. Other key formats such as ED25519 and ECDSA are not supported. Create an SSH key pair. Use the ssh-keygen command to generate SSH public and private key files. By default, these files are created in the /.ssh directory. Openssl req -x509 -newkey rsa:2048 -keyout key.pem -out cert.pem -days XXX req PKCS#10 certificate request and certificate generating utility.-x509 this option outputs a self signed certificate instead of a certificate request. This is typically used to generate a test. Before you can create your CSR, you need to create your Java keystore. Your Java keystore contains your private key. Run the following command to create your 2048 bit Java keystore: keytool -genkey -alias myalias -keyalg RSA –keysize 2048 -keystore c:yoursite.keystore. To create the keys, a preferred command is ssh-keygen, which is available with OpenSSH utilities in the Azure Cloud Shell, a macOS or Linux host, the Windows Subsystem for Linux, and other tools. Ssh-keygen asks a series of questions and then writes a private key and a matching public key. Aug 19, 2019  1. Start by logging into the source machine (local server) and creating a 2048-bit RSA key pair using the command: ssh-keygen -t rsa. If you want to tighten up security measures, you can create a 4096-bit key by adding the -b 4096 flag: ssh-keygen -t rsa -b 4096. After entering the command, you should see the following prompt. I'd rather use 2048 bit RSA for signing together with ECDH for key exchange instead of larger RSA for encryption. Unlike encryption/key-exchange keys, signing keys don't need long term security so 2048 is fine. – CodesInChaos Aug 12 '14 at 11:13.

How do I generate ssh RSA keys under Linux operating systems?
You need to use the ssh-keygen command as follows to generate RSA keys (open terminal and type the following command):
ssh-keygen -t rsa
OR
ssh-keygen
Sample outputs:

The -t type option specifies the type of key to create. The possible values “rsa” or “dsa” for protocol version 2. The $HOME/.ssh stores the following two files:

Rsa 2048 Key Strength

  • $HOME/.ssh/id_rsa – Your private RSA key
  • $HOME/.ssh/id_rsa.pub – Your public RSA key

Please do not share keys file with anyone else. You can upload keys to remote server as follows:
ssh-copy-id userName@server2.nixcraft.net.in
Finally, you can login to remote server as follows:
ssh userName@server2.nixcraft.net.in
scp file.txt userName@server2.nixcraft.net.in:~/data2/
