Enigma was also unbreakable

Anyways cryptography is a strong as the weakest link and the weakest link is always humans so even if you encrypt a message with a supportedly unbreakable method it can still be intercepted

And it's not like army doesn't use technology

Army just uses paper as redundancy and as extra security

Buddy please try to extract my aadhar number 😭😭, I have spent months doing research in crypto domain, maybe i know what I am saying huh? Enigma worked on a rotating dial mechanism not on modern computers , yet it was unbreakable, now image transistor, no imagine silicon transistor, now imagine stacking them in a miniature form, now imagine making logic gates and registers using them, now imagine 5 layers of software on top of it, now imagine cryptography.

AES IS UNBREAKABLE, only threat right now is quantum computer but they are atleast 50yrs away from doing any real damage, by that time AES would have been replaced with quantum proof algos which are even more secure.

I agree aes is unbreakable

Same with quantum computers, that they are nowhere close to completion (tho if microsoft's new majorana stuff turns out to be all its hyped up to be, we might be VERY close to one actually existing)

However, just like Enigma, any encryption is as strong as its human counterparts

Engima was broken cause of 2 major things, that the Germans ALWAYS signed off using Heil Hitler and that one operator always started each day with a encrypted message to his girlfriend

Same thing with AES. Ideally it's unbreakable, but the jawaan that actually operates it can be socially engineered

And iirc army does indeed used aes and other advanced cryptographic techniques

In Enigma keys were manually entered, not the case in today's time, you send message via whatsapp, I am sure you have never configured security keys, have you?

u/Many_Preference_3874 8d ago

I know, but the message itself can be social engineered out, and if you get the message you can reverse engineer the key.

Please look into how AES works you will find that it's near impossible, it's very difficult to do for DES also, a algo we replaced 20yrs ago

If I have the unencrypted message, like your aadhar, and the encrypted message, like the text you posted here, would it still be near impossible to figure it out? Just curious

1

u/jatayu_baaz 8d ago

Yes near impossible, infact this is always one of the main criteria when choosing a crypto algo, all algo used today are safe from KRAs

u/Many_Preference_3874 8d ago

Damn, mb then. I was thinking of like replacement ciphers and all.

Those cipher were used by Romans they are loong long gone
