I am a software engineer by profession and a mathematics undergraduate in the evenings. I speak French, and I am generally interested in operating systems. My corner of the web is here and you might be interested in code I have written.

comment Assistance Cracking Classical Cipher
I agree with the others on providing a little explanation as to how you decoded this. I don't think it needs to be a step by step guide, but a brief overview of what you did would no doubt steer the OP in the right direction :)

comment How to encrypt a File using AES Algorithm?
If you're looking for how to perform file encryption using a programming language, you probably want Stack overflow - a quick search finds these recommended libraries (note: ignore the ROT13 and OTP one) - and the javax.crypto docs should also help. Do remember to search there first, and post what you've tried and are not understanding - as it stands, this will be closed on SO too :)

comment Applying multiple hash functions to improve security?
I've closed this for now as a duplicate of the other question, the discussion on there should help I hope :) If your question is different (and I'm just not seeing it), do feel free to edit/reply to me here and we can look at re-opening it.

comment After implementing a novel encryption algorithm, how would one go about analyzing its security or get help from others in doing so?
Guys, just a friendly note - if you're providing an answer to a question, use the answer box, not the comment box. Big hint - some of these comments are semi answers! :)

comment Why does my implementation of CBC mode only decrypt the first block correctly?
Hello - this is really off topic here and belongs on Stack Overflow; however, before I migrate it there it could really do with an edit - have you nailed down exactly where the issue is? SO likely don't need all of the code you've posted. If you flag when you've had a look at some of SO's questions and edited yours, I'll be able to migrate it there. Please don't cross post :)

comment ECIES protocol - what does the || operation mean?
@eXPi yep. It also means, in this case, that the output of the KDF is split into two parts - one part for each key.
