Tails v6.4: Random Seed on USB Stick to Strengthen Cryptography

Tails is a portable operating system that protects against surveillance and censorship.

Tails v6.4: Random Seed on USB Stick to Strengthen Cryptography
  • "Tails 6.4 is out. It strengths all cryptography, fixes issues when unlocking the Persistent Storage, and more," announced the project.

What's new

  • Random seed. "Tails now stores a random seed on the USB stick to strengthen all cryptography. Having a secure random number generator is critical to some of the cryptography used in Tails, for example, in the Persistent Storage, Tor, or HTTPS. This random seed is stored outside of the Persistent Storage so that all users can benefit from stronger cryptography."
  • Switch to using HTTPS addresses instead of an onion addresses for the Debian and Tails APT repositories. This makes the Additional Software feature more reliable.
  • Update Tor Browser to 13.0.16.
  • Update the Tor client to
  • Update Thunderbird to 115.12.0.
  • Fix more issues when unlocking the Persistent Storage. (#20020#20344#19913)
  • Fix connecting to a mobile broadband network on some hardware. (#20291)
  • Enable again the PDF reader of Thunderbird that we disabled in Tails 6.3 for security.
  • Improve the error message of Tails Cloner when the target USB stick cannot be unmounted because it is being used. (#19253)
  • Fix the homepage of Tor Browser when using the New Identity feature. This removes the error message Tor Browser blocked your homepage from loading. (#20381)
  • Remove the redundant dialog when unlocking a VeraCrypt volume using the Unlock VeraCrypt Volumes utility. (#20281)
