########################################################################

The American Express Secure File Transfer SSH/SFTP public host key is going to be updated on Feb 22nd, 2023.

Description of keys attached:

__Folder Structure__
PROD_2023_SSHHost_Key
	- fingerprint_SSH_Host.txt  -  These are the fingerprints for the key in 3 formats (SHA1, SHA256, & MD5). Use these fingerprints to validate you've 				       installed the correct key when connecting.
	- SSHHostKey2023_openssh.txt  -   Public key in OpenSSH format (text file)
	- SSHHostKey2023_SSH2.txt  -   Public key in SSH2 format (text file)


Note: SSH(SFTP/SCP) file transfer clients automatically accept Host Keys and load into SSH known_hosts file.  

Instructions: 

1.	Logon to the UNIX server through which you connect to SFT. Be sure to login using the same (LDAP) ID through which you connect to SFT application
2.	Go to the home directory of that ID
3.	Locate the .ssh directory. It can be an hidden directory also. You can find this directory by running ‘ls –la’ command.
4.	Go to the known_hosts file inside the .ssh directory.
5.	Edit the known_hosts file and search for the key which begins with ‘fsgateway’.
6.	Note that key might have saved with alerternate host names like: ‘fsgateway.ipc.us.aexp.com’ or ‘fsgateway.intra.ipc.us.aexp.com’ or 'fsgateway.intra.aexp.com'

After execution of above steps you should not get any prompt to accept the new key when connecting to SFT.
