The “ -p” parameter will preserve files’ original modification and access times while copying files along with the estimated time and the connection speed will appear on the screen. $ scp -v :/home/ravi/ssh-cheatsheet.pdf :/home/anusha/.Ĭopy Files with Original Creation Date and Time

If someone has knows your password, your security goes out of the window. It’s actually pretty similar in theory to using your password. RSA is pretty secure and uses a 2048 bit-length by default. This private key ONLY matches with that ONE public key, and the connection needs to be started from the computer that has the private key.
The private key that’s generated is stored on the computer you’re using, and it is never transferred, not even to be verified. RELATED: What Is a PEM File and How Do You Use It? Security Considerations This means that if you wanted to add another public key for your account on this server, you would copy the contents of the second id_rsa.pub file into a new line on the existing authorized_keys2 file. Subsequent public keys can be appended to this file, much like the ~/.ssh/known_hosts file.
