To send us files, we recommend archiving the files in a ZIP or 7-zip format and encrypting it using GnuPG or other OpenPGP compatible software. Please encrypt files to the following recipients (you can encrypt to multiple recipients). These link to our public keys, which you can download.
For files which may be regulated under ITAR, we strongly urge that you follow this level of security.
The encrypted files can be attached to a regular email message. For email message text which may contain sensitive information, this can be placed in a text file together with rest of the files in the archive. We can also read PGP/MIME encoded emails.
