Notes about the TSIG file extension:
To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened
" (Windows 7) or "How do you want to open this file?
" (Windows 10) if you double-click the file. There click on "More apps"
and choose a suitable software to view such files on your PC or from email attachments.
The TSIG file type is primarily associated with 'Top Secret Crypto Gold' by TAN$TAAFL Software Company. Top Secret Crypto Gold is a communications and file encryption program for Windows. It makes it easy for you to chat, keep journals, and write, send, and receive encrypted E-mail and files over the Internet. The detached signature file can be used to verify the integrity of a file and who it was signed by.
