how can i unrar with password

@beothorn
i read the code,it is not supported yet, am i right?

[beothorn]

Yes, not supported. Looking at the code we just print
"archive is encrypted cannot extract"
and exit

@gotson @beothorn
i plan to work on this issue this week, i will do it based on the source code of winrar. Is there anything i need to pay attention to

@beothorn
by the way ,is the code of this project is based on the source code of winrar.I read the code of winrar and I found that the two are very similar

[gotson]

It seems someone already did it in one of the fork, check here koroshiya/junrar@06bdd47

Maybe you can port the changes.

And yes the code is a port of the C code.

i am working on it. koroshiya/junrar is not based on the latest code,so It may take a few days to resolve this matter。

the feature is a fake,I found that his code was not executed.it is amazing that it can still run normally。
I'm still analyzing his code，when the feature is ready,i will push a PR.

I didn't test his fork yet, but i noticed it was using gnu crypto for the Rijndael algorithm (which is not implemented in our version). The jar is added directly in the project, which is bad practice. It seems the jar is available on Maven Central, but the project seems abandoned since 2014.

A good replacement could be Bouncy Castle, which is a well-known crypto library for Java.

I don't agree, i have tested it, and i found it can:

• list content of encrypted files, which is not possible in our version because the file listing is encrypted
• extract password protected files

However, i couldn't extract files from an encrypted archive, i get a CRC error.

hi gotson，I found the key point in koroshiya/junrar.now i unpack the encrypted successfully.
Next, I will replace gnu crypto according to your opinion and add the test case。
After all problems are solved, I will raise PR。
thank you for your advice.

[sunny-shu]

hi gotson，the api of Rijndael is different from the JDK.
I tried many times with jdk's api，It cannot decrypt correctly。
I integrated the original author's code，You do the rectification for Rijndael. is that ok?

[gotson]

You can make a PR, I'll have a look, thanks!
