      Article summary

      Applies to: Lasernet 10

      The Lasernet FTP input and output modules support SFTP. When establishing a connection, Lasernet and the SFTP server negotiate which encryption algorithm (cipher) to use.

      Supported Ciphers

      1. aes128-ctr

      2. aes256-ctr

      3. aes192-ctr

      4. aes128-cbc

      5. aes256-cbc

      6. aes192-cbc

      7. aes128-gcm@openssh.com

      8. aes256-gcm@openssh.com

      9. twofish256-cbc

      10. twofish128-cbc

      11. blowfish-cbc (encryption strength is 128 bits)

      The Cipher Negotiation Process

      When Lasernet and the SFTP server are establishing an SFTP connection, they follow this process to select a cipher:

      1. The SFTP server specifies which ciphers it supports.

      2. Lasernet will sequentially propose its supported ciphers in the order specified above. The connection will use the first cipher that Lasernet and the SFTP server both support.
