Uploading and Downloading Files Using OpenPGP Keys

You can upload and download files using OpenPGP keys. The Public key encrypts the data before the upload starts and Private key decrypts the data prior to the download.

To upload or download a file using OpenPGP keys

1. Connect to your site.

2. In the Local pane (upload) or Remote pane (download), click the file you want to transfer.

3. Do one of the following:

   • On the main menu, click Tools > OpenPGP mode.

   4. In the Key sizeto use list, click a key size. A key is a value that works with a cryptographic algorithm to produce a specific ciphertext (encrypted message) from a specific plaintext (original document). Key size is measured in bits. In cryptography, a bigger the key ensures more secure ciphertext.

   5. In the Key type to use list, click a key type. Key types are the cryptosystems named after their inventors.

   6. To generate the keys, click Generate.

   7. The generated key is added to the OpenPGP Key list. The OpenPGP Key list displays the user id, key id, and key type.
