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.

May 5	revised	Search tool to identify which algorithm is in use Removed post signature - not needed.
May 4	revised	Do public/private pairs work both ways? Slight grammatical fix in the title :)

Apr 26	comment	Advantages of each encryption mode I'm closing this for now as it remains way too broad - we can't just list some advantages based on requirements that might or might not suit your case, because that's just not answerable. Rather than "what are some advantages", explain the situation you are likely to encounter - for example this question asks about maximum key sizes for CBC. Again, David's comments are excellent - you need to be specific. When you're done, flag for re-opening and we'll get the answers coming in again.
Apr 25	revised	How to sign a message using RSA? Change the title to reflect the use of RSA.
Apr 25	comment	cipher text only attack - how to know when to stop when brute-force attack? @gAsk in that case, can I make a suggestion? Give your question a quick edit - thoroughly demonstrate the relevant bits of your work so far. Walk us through it, with relevant examples. If you make an edit and then reply to us here, we can always re-open the question. Closure is not final. If you're struggling with what to add, feel free to grab us in chat.

Apr 23	comment	Can a proof be constructed to show there is no distinguisher? Welcome to crypto.se; your Q has been moved here on account of being more on topic here than on SO - do feel free to register an account to pick up your rep and more importantly responses here :)
Apr 23	revised	Can a proof be constructed to show there is no distinguisher? Some initial tags, tex'd.
Apr 23	comment	How secure is the Vigenère cipher in file encryption if you encrypt the password first? I've taken your "please explain downvoting" out of the question as it kinda gets in the way of the question - and the comment should do it. Unfortunately, there's no requirement on anyone to explain their voting - it's totally anonymous, even from moderators. There have been proposals to require comments and they've been declined - have a look here.
Apr 23	revised	How secure is the Vigenère cipher in file encryption if you encrypt the password first? Removed "explain downvote please" banner.
Apr 22	reviewed	Approve suggested edit on blind-signature tag wiki excerpt

Apr 21	comment	Does the Biclique attack on AES pose a credible risk to its security? Right - I've gone in with a fairly audacious edit - if you don't like it or it isn't what you meant, do feel free to edit/improve it. I have basically taken out the references to all attacks and asked about this specific one, which should help you get the answers you're looking for, I think. If you need help, do feel free to reply to me here, or via a flag, or ask on meta.
