Welcome to Excalibur 0.6.0! This release brings significant security improvements, numerous bug fixes, and performance improvements. Here are some of the highlights:

• New Authentication Protocol: Excalibur now uses the state-of-the-art Augmented Password-based Authenticated Key Exchange (aPAKE) protocol OPAQUE-3DH as the default authentication protocol instead of the legacy Secure Remote Password (SRP) protocol.
• Database-Backed Filesystem: Excalibur moved away from relying on operating-system file management to a database-backed filesystem for a more "logical" organization of files and folders.
• File Name Obfuscation: File and folder names can now be obfuscated to the server and other users for enhanced privacy.
• More Sorting Options: Added more sorting options for the file explorer page, including file size, file type, and creation time.

The Excalibur documentation website was also updated in this release.

Do note that there are several breaking changes to Excalibur in this version. Please follow the 0.6 upgrade guide to upgrade your Excalibur instance to version 0.6. Do also take note of all the breaking changes made to the server API if you are using it.

Server​

💥 Breaking Changes​

• 💥 Changed CLI options for the start command:

  • Renamed --enable-cors/--disable-cors to --enable-cors-validation/--no-cors-validation (since --disable-cors was misleading)

• 💥 Added a new option --auth-protocol to the excalibur user add command

  • It defaults to the new OPAQUE authentication mechanism (OPAQUE-3DH)
  • For SRP compatibility, use --auth-protocol=SRP

• 💥 The File type no longer returns a mimetype value; it is up to the client to derive the MIME type of the file. This affects the following endpoints:

  • /api/files/search (which returns a list of file-score pairs)
  • /api/files/list/{path} (which returns a list of files or directories)

• 💥 Certain endpoints' response content have been removed as their response codes sufficiently indicate the success/failure of the operation. In particular, these endpoints now no longer return any content for the 200 OK status code:

  • /api/files/move (previously returned Item Moved)
  • /api/files/mkdir/{path} (previously returned Directory created)
  • /api/files/rename/{path} (previously returned Item renamed)
  • /api/files/upload/{path} (previously returned File uploaded)

• 💥 We will now use uv's 0.10.x series to build and install the server package, updating the minimum version from 0.9.30 in pyproject.toml and GitHub actions to 0.10.9

✨ New Features​

• ✨ Implemented the OPAQUE-3DH protocol to replace the Secure Remote Password (SRP) protocol

  • Added a new registration endpoint (/api/auth/opaque/register) to handle OPAQUE registration flows
    • This endpoint also allows existing users using SRP to upgrade to OPAQUE
  • Added a new login endpoint (/api/auth/opaque) to handle OPAQUE login flows

• ✨ Implemented a new database-backed file management system, moving away from relying on operating-system file management

  • Folders are now "logical" and not tied to actual directories on the filesystem
  • Files' names are now stored in the database instead of on the filesystem
  • Files are now stored in a single directory on the filesystem, with their database ID as the filename

• ✨ Added new endpoints to get and edit additional user info (/api/users/info/{username} and /api/users/edit-info/{username} respectively)

  • These additional user info are used solely by the client; the server does not use them

• ✨ Added a new endpoint (/api/files/all) to get all files and folders in the user's file system

• ✨ Added a new backup command to the CLI (excalibur backup)

• ✨ Made responses return X-Content-Type-Options and X-Frame-Options headers

  • The values are X-Content-Type-Options: nosniff and X-Frame-Options: DENY

🔄 Changes​

• 🗃️ Modified the Excalibur database:

  • Modified the User table:
    • Added auth_protocol, additional_info, and registration_record fields
    • Made srp_group, srp_salt, and srp_verifier fields optional (since they are not used for the OPAQUE-3DH protocol)
  • Added the FSItem table

• 🗃️ Added authentication protocol information (auth_protocol) to be returned by the security details endpoint (/api/users/security/{username})

• 🗃️ The File and Directory types now return a creation_time field representing the creation timestamp of the item. This affects the following endpoints:

  • /api/files/search (which returns a list of file-score pairs)
  • /api/files/list/{path} (which returns a list of files or directories)

• 🗑️ The following endpoints no longer return the corresponding response codes:

  • /api/files/download/{path}: Removed 406 Not Acceptable, corresponding to an "Illegal or invalid path"
  • /api/files/upload/{path}: Removed
    • 406 Not Acceptable, corresponding to an "Illegal or invalid path"
    • 414 URI Too Long, corresponding to a file path that is too long
  • /api/files/mkdir/{path}: Removed
    • 406 Not Acceptable, corresponding to an "Illegal or invalid path"
    • 414 URI Too Long, corresponding to a directory path that is too long
  • /api/files/list/{path}: Removed 406 Not Acceptable, corresponding to an "Illegal or invalid path"
  • /api/files/check/path/{path}: Removed
    • 406 Not Acceptable, corresponding to an "Illegal or invalid path"
    • 414 URI Too Long, corresponding to a directory path that is too long
  • /api/files/check/dir/{path}: Removed 406 Not Acceptable, corresponding to an "Illegal or invalid path"
  • /api/files/delete/{path}: Removed 406 Not Acceptable, corresponding to an "Illegal or invalid path"
  • /api/files/move/{path}: Removed
    • 406 Not Acceptable, corresponding to an "Illegal or invalid path"
    • 414 URI Too Long, corresponding to a path that is too long
  • /api/files/rename/{path}: Removed
    • 406 Not Acceptable, corresponding to an "Illegal or invalid path", replacing it with 400 Bad Request corresponding to an "Illegal or invalid name"
    • 414 URI Too Long, corresponding to a path that is too long

  The documentation has been updated to reflect these changes.

• 🧹 Subdirectories returned by /api/files/list/{path} will no longer have items returned

  • Previously, any subdirectories' items field would be set to null. Now the field is omitted entirely

🐛 Bug Fixes​

• 🐛 Fixed a bug where unbounded timestamps in the future were allowed as timestamps during the Proof-of-Possession (PoP) validation process

  • Now only timestamps within the configured tolerance are allowed

• 🐛 Fixed wrong exception being returned if the WebSocket credentials are incorrect

• 🐛 Fixed certain CLI commands (i.e., excalibur db ui and excalibur test) returning incorrect error codes

• 🐛 Fixed an issue where multiple file listener connections with the same communications UUID from the authentication token would override each other, causing all non-latest connections to not receive any updates from the server

• 🐛 Fixed a bug where returning nothing in some endpoints gives "Response content shorter than Content-Length" internal server errors

• ✏️ Fixed typo in the add user endpoint documentation.

🗑️ Deprecations​

• 🔥 Removed old operating-system file management code

  • Please migrate to the new system using the excalibur db migrate-files command

• 🗑️ Deprecated Secure Remote Password (SRP) related code

  • Users can still register and log in with SRP, but it is recommended to use OPAQUE-3DH instead
  • Endpoints and code relating to SRP will be removed in a future update
