In Symphony versions 20.9 and higher, users can encrypt content export files and access the SFTP site with enhanced security using a private key.
To configure the export file encryption feature, the user must generate the SSH keys (for SFTP download of the exported files) and the PGP key (for decryption of the exported files).
Note: This process is optional for clients with on-prem Key Managers and Content Export Bridges
Refer to the documentation in Symphony Docs linked below for more information on this feature, including configuration, download and decryption:
Note: Refer to the Knowledge Article found here on how to access Content Export SFTP with RSA encryption configured via FileZilla and WinSCP
