Transfer of files and security level

Below you will find information about how files can be transferred at different security levels (for security reasons, OsloMet staff can no longer receive zip-files), see Type of research data.

File Sender

Uninett`s File Sender service can be used to upload/download large files, with up to 100 recipients. The files are automatically deleted after 20 days. The service is only available to users who log on via FEIDE (universities and university colleges in Norway and the Nordic countries), but users who do not have a FEIDE logon can receive files from File Sender.

You can heighten security by encrypting the file you send by e-mail and by sending the encryption code through a different channel, such as by text message. Log on to File Sender from the tool menu here. Contact IT Service Desk if you need help to start using the service or if you have any questions.


When you need to send files to recipients who do not have a FEIDE logon, you can use the BOX alternative. BOX is used to share directories in a cloud solution. Anyone can add files to a shared directory. You should encrypt files before sharing them via BOX.

More information about Box here.

Contact IT Service Desk if you need help to start using the service or if you have any questions.

Sending encrypted external hard drive by registered post

At the highest security levels (8–9), you should consider whether it is necessary to send the research data. An alternative is to encrypt the file, store it on an encrypted external hard drive and send it by registered post.

File encryption with PGP-key

Several institutions included OsloMet holds barred for receiving files of type "zip" . Instead of encrypting a file using 7Zip you can encrypt with PGP-key (Gpg4Win). A file encrypted with PGP key is very secure if that key is taken care of properly, for example can an existing zip-archive be treated this way.
