Mirsal is a web based application that allows authenticated users to securely and easily send arbitrarily large files to other users. Users without an account can be sent a guest upload voucher by an authenticated user. Mirsal is developed to the requirements of the higher education and research community. It is primarily of interest to users who need to send files larger than those allowed by e-mail systems (typically limited to 10MB to 20MB depending on the e-mail system).
Mirsal is currently configured to allow files to be sent up to 50GB in size, although due to typical end-user network connection speeds and network performance conditions, it will be most useful for files in the 10MB to 50GB range. Unlike regular e-mail attachments, where the contents are included in the e-mail, Mirsal places the file contents on the Mirsal server and an e-mail is sent to the specified recipients informing them how they can retrieve the file that has been temporarily stored on the Mirsal service.
A file placed on this service is automatically deleted after at most 10 days (whether or not it has been retrieved by the intended recipient(s)), and once deleted, is not available for retrieval by either the user who placed the file on the server or the intended recipient(s).
Login to upload your files or invite people to send you a file.
If you have received an invitation to access this site as a guest
then the email will contain the information you will need to access
this site and upload files.
The login button on the top right of the page should let you login
using standard institutional account. If you are unsure
about what login credentials to use to access Mirsal then
please contact your local IT support.
As an authenticated user you should be able to upload files one or
more times and either have Mirsal email the recipients after
your upload completes or provide you with a link to allow file
download. You should also be able to invite other researchers to
the system to upload one or more files as a guest.
For guests...
If you have been sent a guest voucher from this site you have been
invited to upload files one or more times. The simplest way to do
that is using the information contained in the invitation email.
When uploading as guest, be sure to verify that any links in the
guest invitation email are to a Mirsal that is running on a
research facility you trust. If you are not expecting a guest link
from a facility you know then the email might not be legitimate.
The user who invited you to this system might have done so
allowing you to upload files and get a link to allow other folks
to download those files. If you can not get a link then you will
have to provide email address(es) of the people who you wish to
invite to download the uploaded files.
Possible Download Size Limitations
Any modern browser will download files of any size from the site.
Nothing special is required for downloads.
Possible Upload Size Limitations
If your browser supports HTML5 then you should be able to upload
files of any size up to 50 GB. Current versions of Firefox and Chrome on
Windows, Mac OS and Linux are known to have HTML5 support.
Your browser's features
You can upload files of any size up to 50 GB per transfer and you can resume uploads.
You can upload files of at most 2 GB each and up to 50 GB per transfer.
Uploads of any size with HTML5
You'll be able to use this method if the sign is displayed above
To enable this functionnality simply use an up to date browser that supports HTML5, the latest version of the "language of the web".
Up to date versions of Firefox and Chrome on Windows, Mac OS X and Linux are known to work.
You can resume an interrupted or cancelled upload. To resume an upload, simply send the exact same files again !
Make sure the files have the same names and sizes as before.
When your upload starts, you should notice the progress bar jump to where the upload was halted, and continue from there.
End-to-End Encryption
Mirsal has an optional security feature that allows end-to-end encryption. The encryption is done in your browser so Mirsal never has visibility of your unencrypted files, allowing you to transfer sensitive data securely.
Files up to 2 GB can be send using encryption. All you have to do is send the recipient a ‘key’ via a second channel: telephone or SMS, for example. The recipient then enters this key, which allows them to download the file.
This way, you can determine who is allowed access to your valuable research data or confidential files.
Uploads up to 2 GB per file without HTML5
Mirsal will warn you should you try to upload a file that is too big for this method.
Resuming uploads is not supported with this method.
