How does public key authentication work in SFTP?
When the server asks the client to authenticate, the client uses the private key to encrypt some data that is already known by the server (e.g. the user-name); the client sends the encrypted data back to the server; the server decrypts it with the public key.
How many SSH key pairs are there in SFTP?
In every SSH/SFTP connection there are four keys (or two key-pairs) involved. This article explains a difference between them and what keys an SFTP client user needs to care about. The SSH employs a public key cryptography.
Why is it important to use SFTP for SSH?
The server thereby knows that the client has possession of the private key and assumes that it’s therefore OK to permit access. This illustrates the importance of keeping the private key confidential. SFTP is a protocol that allows file-transfer over SSH connections.
What’s the difference between public and private SSH keys?
This article explains a difference between them and what keys an SFTP client user needs to care about. The SSH employs a public key cryptography. A public-key cryptography, also known as asymmetric cryptography, is a class of cryptographic algorithms which requires two separate keys, one of which is secret (or private)…
