# SFTP Server

<h2 id="sftp">
  Connecting to the SFTP Server
</h2>

The BRP Connect portal provides an SFTP URL to connect to.
You can add users there with either a randomly generated password
or by providing a public SSH key for authentication (recommended).

Only SSH public key formats are accepted. Here are some examples of what they look like:

```
# elliptic curve key example
ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIOvwPMKJINWEODRavdC7g6Y+isDF/eDRurSPL4A72uuR

# RSA key example
ssh-rsa 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
```

You can generate a new private/public key pair with the `ssh-keygen` utility:

```
ssh-keygen -t ed25519 -f "~/.ssh/<your_keyname>"

# Linux/MacOS/Windows CMD
cat ~/.ssh/<your_keyname>.pub

# PowerShell
Get-Content $env:USERPROFILE\.ssh\<your_keyname>.pub
```

  SFTP Server Contents
</h2>

1-Click PPA nominations for the next day are calculated
and provided every day at **12:00 PM** (`Europe/Berlin` timezone).

Revisions may happen throughout the following hours,
which will trigger new files being created in `archive/`
and the existing ones being updated in `current/`.

```
# Latest daily exports
nominations/current/YYYY-MM-DD.csv
nominations/current/YYYY-MM-DD.xlsx

# Versioned archive ([x]: numbering starting at 1)
nominations/archive/YYYY/MM/DD/v[x].csv
nominations/archive/YYYY/MM/DD/v[x].xlsx
```

<Note>
  Each export is available as CSV (for machine reading) and XLSX (for human consumption). See [File Formats](/brp/sftp-formats) for column definitions and [File Examples](/brp/sftp-examples) for sample downloads.
