Decrypt GOST R 50739-95

[Youn]

Hello,

I have deleted sensible informations (less than 10Mo) with Kaspersky antivirus using GOST R 50739-95.

I would like to take it back but it is impossible with standard softwares.

How can I do to find and decrypt the erased datas on my USB key?

Hello @Youn, welcome.

The file shredder is a secure replacement for the windows or other OS erase method. Its advantage is just that a file deleted in this way can not be restored.
If you do not have a backup of the data, it is lost.

Informaticians of intelligence services may get it back?
