This pull request includes significant changes to the DigestAuthorizationHeader class and related files in the Cuemon.AspNetCore.Authentication namespace. The changes focus on improving the handling of the Digest authentication process, deprecating obsolete properties and constructors, and enhancing the formatting of the WWW-Authenticate header.

Improvements to DigestAuthorizationHeader class:

  • Introduced a new constructor for the DigestAuthorizationHeader class that omits the stale parameter, streamlining the creation of header instances.
  • Marked the stale property and the constructor that includes the stale parameter as obsolete, indicating they will be removed in future versions. [1] [2]
  • Modified the ParseCore method to use the new constructor without the stale parameter.
  • Enhanced the ToString method to avoid appending empty fields and added a helper method to format fields correctly.

Changes in DigestAuthenticationHandler and DigestAuthenticationMiddleware:

  • Updated the WWW-Authenticate header formatting to remove quotes around the stale and algorithm values, ensuring compliance with the Digest authentication specification. [1] [2]

Additional changes:

  • Adjusted the Create method to set the CredentialsDelimiter to a comma, aligning with the expected format for Digest authorization headers.
  • Added a suppression message for the new constructor in GlobalSuppressions.cs to address the "Methods should not have too many parameters" code smell.

Summary by CodeRabbit

  • Bug Fixes
    • Updated the authentication challenge header formatting to remove unnecessary quotes, ensuring consistent parameter representation in responses.
  • Refactor
    • Streamlined the header construction by adjusting credential delimiters and deprecating outdated parameters for a cleaner, more maintainable authentication process.
    • Marked certain parameters as obsolete to improve future compatibility.
    • Removed reliance on the stale parameter and updated handling of credentials.

Walkthrough

The changes adjust the Digest authentication implementation by modifying the header construction and parameter handling. In both the authentication handler and middleware, quotes around the stale parameter in the WWWAuthenticate header are removed, treating the value as a variable. The DigestAuthorizationHeader class is updated to use a comma as a delimiter, eliminate the stale parameter from its primary constructor, and mark related members as obsolete. Additionally, a duplicate suppress message attribute for the DigestAuthorizationHeader constructor has been added in the global suppressions file.

Changes

.nuget/.../PackageReleaseNotes.txt Documented bug fixes related to the removal of quoted string values for the stale and algorithm parameters across relevant classes.
CHANGELOG.md Updated version to [9.0.4] and expanded description to include bug fixes and changes to parameter handling in authentication classes.

Poem

I'm a rabbit in the code, leaping through the bytes,
Watching stale quotes vanish like fading lights.
The headers now prance with a cleaner display,
Variables shine clear in a bold new way.
Hopping past deprecated bits with a joyful cheer,
Celebrating these changes with a digital carrot dear!

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • I pushed a fix in commit <commit_id>, please review it.
    • Generate unit testing code for this file.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai generate unit testing code for this file.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
    • @coderabbitai read src/utils.ts and generate unit testing code.
    • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
    • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
