Secure File Transfer

DigiSecret can be used for sending files over the Internet or Local Area Network securely. Your data is automatically encrypted before it is sent and decrypted when it is received. In order for the recipient to successfully receive your files or folders, he/she must know the passphrase that you used to protect the files being sent. The passphrase must be agreed upon before the file transfer takes place, and it cannot be transmitted openly. If your passphrase is intercepted, the whole purpose of secure file transfer is defeated-whoever intercepted the passphrase may also intercept the files that you send and recover them. It is highly recommended to use a secure channel (e.g. PGP) for agreeing upon a secret passphrase.

To send files or folders, drop them on the program main window or click on the Add toolbar button and select the files/folders you want to send. Click on the Send toolbar button or Actions => Send to Other Users ... . A dialog window will appear. Enter the recipient's IP address or hostname in the Remote IP address/hostname field and select your preferred encryption algorithm from the Encryption algorithm menu. If you are sending an encrypted archive, the Encryption algorithm menu is disabled. The recipient's address may already be in the address book; in this case, you can select it by clicking the Addr. Book button and double-clicking on the address line, or, if the recipient is on the local network, you can find the recipient by clicking the Browse button. Type your passphrase in the Enter Passphrase field and confirm it in the Re-enter field. If you would like to see the passphrase as you type it, check the Show typing checkbox. If you would like to enter your passphrase without using the keyboard, click on the Virtual Keyboard button. Click the Advanced button if you would like to change the remote TCP port number for this session, or if your network connection is routed via a SOCKS5 firewall and you need to enter SOCKS5 server settings. When you are ready to send, click the Encrypt & Send button to initiate file transfer.

If you would like to receive files, you need to deploy DigiSecret Agent. If it does not launch at Windows startup, you will need to start it manually by clicking Start => Programs => DigiSecret => DigiSecret Agent . When someone sends files to you, a dialog window will pop up that will show the sender's IP address and hostname, and prompt you for a passphrase. To start receiving files, enter the passphrase and click the Accept & Receive button.

You can also send files to other DigiSecret users by right-clicking on them in the Windows Explorer and selecting DigiSecret =>Send to DigiSecret User
