SFTP connections are set up together with the Auxia team. Your Auxia point of contact creates your SFTP user and ingestion; you generate a key and send the files.

​
Prerequisites

  • A system or tool that can send files over SFTP on a schedule
  • The ability to generate an SSH key pair, or an export tool with a built-in key generator
  • If your outbound firewall restricts destinations: permission to allowlist an IP address

​
Setup instructions

1

Tell Auxia about your feed

Share these with your Auxia point of contact:
2

Generate an SSH key pair and send the public key

Generate the key pair on your side and send Auxia the public half only. Auxia accepts OpenSSH-format keys: ED25519, or RSA of 2048 bits or more.
Many export tools have a built-in Generate SSH keys option that does the same thing. Keys in PuTTY (.ppk) or PEM-wrapped format need converting to OpenSSH format first.
Never send your private key — to Auxia or anyone else.

Receive your connection details

Auxia creates your SFTP user and sends you:
  • Host and port (22)
  • Username
  • Host key fingerprint — check it the first time you connect, to confirm you’re connecting to Auxia
  • The folder path(s) to upload to
  • Auxia’s PGP public key, if you encrypt files
4

Send a test file

Connect and upload a test file to your folder:
Auxia confirms the file arrived and can be read, then switches the feed to production.

​
Encrypting files with PGP

If your files must be encrypted, encrypt them with Auxia’s PGP public key before uploading. Auxia decrypts them when they’re read — there’s no separate decryption step on your side.
Encrypt only — don’t sign. Signed files fail to decrypt.
Tell your Auxia contact up front if you plan to encrypt, so the key exchange can happen alongside setup.

​
Rotating your SSH key

Send Auxia your new public key. Auxia adds it alongside the old one, and removes the old key once you’ve confirmed the new one works — so there’s no downtime.
