Register an SSH key

Use this task to register an SSH private key in DCT Compliance. Once registered, the key is available to select when creating SFTP file connectors with Public Key Authentication. SSH key registration is available through the API only; there is no GUI for this step.

Prerequisites

You have an SSH private key file for the SFTP server.
You have access to the DCT API (Swagger interface or REST client).

Steps

Upload the private key file to the DCT file upload endpoint:
Copy
```
POST /v3/masking-file-uploads
Content-Type: multipart/form-data

file: <your-private-key-file>
```
The response returns a file_reference_id. Copy this value — you need it in the next step.
Create the SSH key in DCT using the file reference ID from the previous step:
Copy
```
POST /v3/ssh-keys
Content-Type: application/json

{
  "name": "my-sftp-key",
  "private_key_file_reference_id": "<file_reference_id>"
}
```
DCT creates an SSH key registration job. Wait for the job status to return as COMPLETED before proceeding.

The registered SSH key is now available in the Public Key Authentication option when creating an SFTP file connector. See Create a file connector.
