ssh-keygen
utility.
Specify a filename
for the private key. Also specify the RSA type and a size of 2048.
The command format is: ssh-keygen -b 2048 -t rsa -f filename
For example: ssh-keygen -b 2048 -t rsa -f mykey
Enter passphrase (empty for no passphrase): YourPassphrase
Note:
While a passphrase is not required, Oracle recommends using one as a security measure to protect the private key from unauthorized use. When you specify a passphrase, a user must enter the passphrase every time the private key is used.
The ssh-keygen
utility creates two files:
filename
- The private key
filename.pub
- The public key
