I want to decrypt a file that is decrypted using this command line

openssl.exe enc -d -in input.ENC -out output.txt -pass file:keyfile.key -des3

I want to be able to decrypt it using Java. (JDK8)

Thanks in advance for tips.

    ...so are you expecting us to just give you a list of libraries, approaches, tips, tricks and code with unit tests that solves your problem? I do apologize if that came across as impolite, but I personally see it as impolite to ask a question as broad as this without any prior work done on your part. C'mon; we're volunteers here. Respect our time too. – Makoto Feb 20 '18 at 17:16

  • Usually [`EVP_BytesToKey`](http://wiki.openssl.org/index.php/Manual:EVP_BytesToKey(3)) is one of the issues.

  • @Makoto - OpenSSL gets so many of the *"write the code me for in {language}"* questions I have a cheat sheet with copy/paste for the dups... As soon as we figure out the match we can close it. – jww Feb 20 '18 at 19:25
