Specifies a list of ciphers that Integration Server supports for communication with an SFTP server. When establishing a connection to an SFTP server, these are the ciphers that Integration Server, acting as an SFTP client, presents to the SFTP server.

The default values are: aes256-ctr,aes192-ctr,arcfour,arcfour128,arcfour256.

To include any other ciphers, append the cipher to the comma-separated list. To remove a cipher, delete the cipher from the list. You may want to remove a cipher if the cipher has known vulnerabilities.

Specifies a comma-separated list of the key exchange algorithms that will appear in the Preferred Key Exchange Algorithms list when creating or editing an SFTP server alias. Specify only the key exchange algorithms that are not deemed to be vulnerable. Do not list key exchange algorithms deemed to be vulnerable The Preferred Key Exchange Algorithms list will display the key exchange algorithms in the same order in which the configuration parameter value lists the algorithms. The default is “”, which means that Integration Server displays all key exchange algorithms in the Preferred Key Exchange Algorithm list.

Enables JSch logging. When this property is set to true, all the logs from JSch will be printed on Integration Server console. The default is false.

Specifies the order of message authentication code (MAC) algorithms for client to server transmission. The default value is the default order of MAC algorithms that Integration Server acting as an SFTP Client supports. To disable use of a MAC algorithm for client to server transmission, delete it from the watt.ssh.jsch.mac_c2s value.

Specifies the order of message authentication code (MAC) algorithms for server to client transmission. The default value is the default order of MAC algorithms that Integration Server acting as an SFTP Client supports. To disable use of a MAC algorithm for server to client transmission, delete it from the watt.ssh.jsch.mac_s2c value.
