The service cryptshare allows a secure transfer of files up to 20 GB total size and can be reached at cryptshare.tu-clausthal.de. The users of TU Clausthal can upload files via web interface and make them available for others to download or upload files from other sites.
The entire process - uploading, caching and retrieval - is secured by cryptographic methods. Notifications are automatically sent by e-mail. The only requirement is the use of a tu-clausthal.de e-mail address on the sender and/or recipient side.
Both messages and files can be sent to one or more recipients, similar to a normal e-mail. You must verify your email before sending, and for added security you can set a password to retrieve the files.
