v1.0.9

Noteworthy changes:

• Online help was improved in look and content for many plug-ins, and has LaTeX-like formulas now for nearly all visual plug-ins (Thank you to @tassadarius for the tireless work on issue 320 and more).
• Online help urls are using the https-Protocol where possible. Dead links were removed or updated (Thanks to @tassadarius for the dead link checker!).
• The Rabin Cryptosystem was introduced as a new plug-in (Thank you, @ocir).
• The Signal Encryption visualization was introduced as a new plug-in (Thank you, @tassadarius).
• For Taxman / Numbershark, built-in optimal strategies are expanded up to n=1000.
• For TaxMan / Numbershark, an optimal parallel solver was introduced (Thank you, Brian Chess).
• The Certificate Verification plug-in was updated for better date display and usability.
• JCT was updated to run on Java 17.
• A standalone JRE is now delivered built-into the JCT product for Mac OS; JCT runs now standalone on all operating systems (Windows, Mac OS, Linux).
• The Rich Client Platform of JCT was updated to Eclipse RCP 2022/12.
• Updates for stable releases (like v. 1.0.9) are now delivered via the JCT update sites on a track (update site) that is separate from the weekly builds.

Instructions for MacOS

JCrypTool currently does not sign its weekly releases with a key that is known to Apple. As a consequence, the application may be flagged as not trustworthy. To run this release under macOS, do:

• Dowload the JCrypTool and extract the .tar.gz file by double clicking it.
• Open a "terminal" window (in Finder: Menu "Finder → Service → New terminal in folder"; or press "Control-Option-Command-T" while selecting the folder from its parent folder). Enter the following command there:

sudo xattr -r -d com.apple.quarantine ~/Downloads/jcryptool.app

(assuming you extracted JCrypTool directly in the folder "Downloads"; otherwise, adapt the command accordingly. The .app file ending should be kept.)

Then, start the extracted app by double-clicking the file "jcryptool.app".

These steps only have to be done this once — the next times JCrypTool ist started they are not necessary.
