It seems there is an issue with the roror II in Enigma tool.

Steps to reproduce:

1. Open Practical Cryptography's Enigma tool
2. Set the following values:

Plaintext: SOMESECRETMESSAGE
key settings: VEZ
ring settings: ABD
Rotors: 324
Plug board settings: GT YC EJ UA RX PN IS WB MH ZV

3. Press Encrypt/Decrypt
4. Copy cipertext value to Dencode Enigma tool
5. Configure Dencode Enigma tool with the above mentioned settings. (Reflector UKW-B)

Result: message is decrypted correctly.

6. In the Practical Cryptography's Enigma tool set rightmost rotor to 5 (to be 325)
7. Repeat steps 3-4

Result: message is decrypted incorrectly.

8. In the Practical Cryptography's Enigma tool set middle rotor to 3 (to be 335)
9. Repeat steps 3-4

Result: message is decrypted correctly.

So it seems that combinations of the middle rotor II + rightmost rotors V..VIII produce incorrect results.

I've also tested CacheSleuth tool, and it behaves like Practical Cryptography's one, i.e. it has no such issue.

P.S. Thanks to @the-lambda-way

In ISO 8601 the first week of the year is the one with the first Thursday in it.
Currently, the date converter gives the week with 1 January in it as the week 1 in the output "ISO8601 Date (Weeks)", so, for years that starts in Friday, Saturday or Sunday, the week numbers of all the days are 1 week ahead and the first 3 days of the year are 1 year ahead.
Examples, the dates:
2016-12-31
2017-01-01
Output:
2016-W53-6T00:00:00Z
2017-W01-7T00:00:00Z
They should be:
2016-W52-6T00:00:00Z
2016-W52-7T00:00:00Z

I guess some lines need to be added in:
src/main/java/com/dencode/web/servlet/pages/DencodeServlet.java
Incorporating the format for week year (YYYY instead of yyyy) in the pattern string and setting the minimal days required in first week to 4 in the Calendar used by the DateFormat object.

First I love your dencode, it's what I really needed badly to convert UTF-16LE to Hex to work on some tables in Cheat Engine. and works perfectly and quickly. I was trying to build it but I keep getting this error. I'm not an advanced user and never used "Grandle" before, but I have built applications in Github with no issues. I'm really curious how I can get dencode working offline because I want to learn the trick to building it without getting this error:

dencode-web>gradlew appRunStage

Deprecated Gradle features were used in this build, making it incompatible with Gradle 9.0.

You can use '--warning-mode all' to show the individual deprecation warnings and determine if they come from your own scripts or plugins.

For more on this, please refer to https://docs.gradle.org/8.4/userguide/command_line_interface.html#sec:command_line_warnings in the Gradle documentation.

I have Java SDK 17 and 21 installed on my computer so I have no idea what I'm doing wrong. I set my Java bin directory path in Environmental Variables too. Any help so I can get your awesome dencode working for me locally?

On https://dencode.com/string/ascii85, the second example shows 6F000000(16)
= 1214606444(10), which is wrong (copy-paste error from first example). Correct decimal value is 1862270976. The div/mod calculation of the second example is correct.

Is it possible to add small caps converter? i.e. abcdefghijklmnopqrstuvwxyz to ᴀʙᴄᴅᴇꜰɢʜɪᴊᴋʟᴍɴᴏᴘꞯʀꜱᴛᴜᴠᴡxʏᴢ

Note: “LATIN LETTER SMALL CAPITAL X” does not exist and plain small letter x is used instead.

Hi!

This is a great project! ❤️

I would like to write and publish a PowerToys Run plugin that use your API.

Can I POST to https://dencode.com/dencode from the plugin?
Would that be fair use of the API?
Would you prefer that I set a specific user agent for those requests?

Thanks!
