Sent files might be more sensitive than the discussion so the file itself is never logged, only placeholder data. This hides even the max number of actual messages sent. There’s also an option (disabled by default) to log noise packets during trickle connection (constant transmission). This means the number logged entries reveals no more metadata than what communication over XMPP server reveals. Furthermore, the logged data is not the message itself, but the assembly packet delivered to contact. On the other hand each, all logged messages are written to same database so only max number of sent messages is revealed. Number of entries (sent messages is not padded). Each entry contains padded date, contact information and the message. Message log database works a bit differently. There’s protective logic that prevents down-scaling database size if there’s more contacts that would be possible after down-scale. These databases can be scaled upwards in size when user adds more and more contacts. There are two settings for group: Maximum number of groups and maximum number of members per any group. This database padding applies also to groups that now contains the name of group, logging setting and list of members. This works fast enough even with gen1 RPi under default settings. The entire database is re-encrypted with new nonce after every message. This is used to pad the number of entries in the database. There’s a setting that defines the maximum number of contacts. I put extra care into separately padding every data field per contact. There’s a contact database with simple structure that contains accounts, user accounts, nicks, forward secret symmetric message keys, static symmetric hash ratchet counter (harac) header keys, public keys used during key exchange (private keys are ephemeral and discarded after symmetric keys are derived) and some settings like logging (TxM/RxM), file reception and window notification privacy (RxM). Group files contained plaintext list of group members, and log files contained the plaintext log. Previously keyfiles were unencrypted files containing the keys changed by hash-ratchet. It’s been six months and the next version of TFC, 0.16.10 is now IIRC you talked about locally encrypting TFC’s keys a long time ago. How private is YOUR messaging app? Charity rates WhatsApp as the most secure – but experts aren’t so sure ![]() Some of these issues have not been fixed due to high complexity for the proposed fixes, but workarounds have been presented in the documentation for VeraCrypt.” “This public disclosure of these vulnerabilities coincides with the release of VeraCrypt 1.19 which fixes the vast majority of these high priority concerns. They found:ġ5 Low or Informational Vulnerabilities / Concerns VeraCrypt, the successor to TrueCrypt, has been audited by QuarksLab. Not patching it for such a long period is inexcusable. ![]() Here’s more proof, if needed, that open-source software isn’t necessarily more secure. I hope this can be added.The Dirty Cow vulnerability has been present in Linux for nearly 9 years.
