      Use the ed22519 public key as the group session id. · d62e344d
      Mark Haines authored
      Some clients expect the session id to be globally unique,
      so allowing the end devices to pick the session id will cause
      Include the current ratchet index with the initial keys, this decreases
      the risk that the client will supply the wrong index causing problems.
      Sign the initial keys with the ratchet ed25519 key, this reduces the
      risk of a client claiming a session that they didn't create.

      Fix megolm decryption of UTF-8 · 1d4c13c7
      Richard van der Hoff authored
      Repeat the fix from b10f90d for megolm messages.
      It turns out that the 'length' argument to 'Pointer_stringify' doesn't work if
      the input includes characters >= 128.
      Rather than try to figure out which methods can return UTF-8, and which always
      return plain ascii, replace all uses of Pointer_stringify with a 'length'
      argument with the version that expects a NULL-terminated input, and extend the
      buffer by a byte to allow space for a null-terminator.
      In the case of decrypt, we need to add the null ourself.
      Fixes https://github.com/vector-im/vector-web/issues/2078.

      OlmSession.has_received_message · 2e9021c2
      Richard van der Hoff authored
      I find myself wanting to know if an OlmSession is in the pre-key state or not,
      to help debugging at the application level.

      Create new constants for key lengths, etc · 39212987
      Richard van der Hoff authored
      We were using olm::KEY_LENGTH for everything under the sun which happened to be
      32 bytes long, and making a bunch of assumptions in the process. Create a bunch
      of new constants (as C #defines rather than C++ consts so that I can use them
      in another forthcoming refactor).

      Fix Ed25519 keypair generation · 0c462cff
      Richard van der Hoff authored
      Ed25519 private keys, it turns out, have 64 bytes, not 32.
      We were previously generating only 32 bytes (which is all that is required to
      generate the public key), and then using the public key as the upper 32 bytes
      when generating the per-message session key. This meant that everything
      appeared to work, but the security of the private key was severely compromised.
      By way of fixes:
       * Use the correct algorithm for generating the Ed25519 private key, and store
         all 512 bits of it.
       * Update the account pickle format and refuse to load the old format (since we
         should consider it compromised).
       * Bump the library version, and add a function to retrieve the library
         version, so that applications can verify that they are linked against a
         fixed version of the library.
       * Remove the curve25519_{sign, verify} functions which were unused and of
         dubious quality.

      Add an install and an install-debug targets · c8d00665
      Emmanuel Gil Peyrot authored
      This makes the user able to use the familiar `make install` syntax, and
      allows overriding of the default directories using the DESTDIR and
      PREFIX variables, for example:
       make DESTDIR=packaging PREFIX=/usr install

      Specify the soname in the library and its name · 06cdb3f7
      Emmanuel Gil Peyrot authored
      This provides users of this library the guarantee that the ABI will
      stay stable when MAJOR will reach 1, and will stay backwards compatible
      for the entire duration of the 1.x.y branch.
      It does require the maintainers to always update the version in the
      Makefile at every ABI change.

      Make space in the session pickle for chain index · 8dd3c182
      Richard van der Hoff authored
      Keeping track of the chain index is a useful thing to do, but is only required
      if we've enabled diagnostics. Extend the session pickle format to make a space
      for it, so that pickles can be transferred between the logging_enabled branch
      and the master branch without loss of information.
      Also add some tests for session pickling which explicitly check that we can
      unpickle both formats of pickle.

      Remove unused 'chain_index' from Ratchet · 757c4225
      Richard van der Hoff authored
      This was introduced when I was experimenting with support for logging progress
      in Olm. That is now relegated to the logging_enabled branch, so this should
      probably be removed.
      This also fixes the incompatibility of session pickles from the current master
      branch with those from olm 0.1.0.
