Can you reverse engineer private key from public key?
What you need to do is read up on Public-Key Cryptography. The short answer is it is based on an algorithm that allows one key to encrypt and the other key to do the decryption, which is why you cannot work backwards.
Can Bitcoin be reverse engineered?
A Bitcoin address is a quantum-proof one-way hash of the public key which is impossible to reverse engineer. Since approximately half of all bitcoin addresses have their public key revealed. Any quantum attack of this scale would likely prove fatal to the entire network.
Can we use public key to decrypt data?
In public key cryptography, every public key matches to only one private key. Together, they are used to encrypt and decrypt messages. If you encode a message using a person’s public key, they can only decode it using their matching private key.
Can a reverse engineer reverse engineer an encryption program?
If they have access to the decoding program for symmetric key encoding (like your XOR), or the encoding program of asymmetric key encoding, the encoding is most likely instantly defeated by reversing it. If you have access to a black box which does the encryption, you can get a lot of information by feeding it particular input values.
What can I use to reverse engineer a private API?
To implement a sniffing proxy used to reverse engineer the private API, I’ll use tool called mitmproxy. You can use any other transparent HTTPS proxy. Charles is another example with a nice GUI. To make this work we need to set up the following things:
How can I reverse engineer a dictionary attack?
A dictionary attack could already provide some insight in the XOR key used, where you’d XOR the 6 hexadecimal values with lots of words of 6 characters just to see which one return another word in your dictionary. The ones that seem to return valid words could be the keys you’ve used to XOR the original.
Why was reverse engineering important in World War 2?
This is where “reverse-engineering” really begins, because he can test his hypotheses about the algorithm against known input and output. In World War II, cryptanalysts worked hard to build extensive lists of “cribs”—words that were likely to appear in the enemy’s messages—to exploit known-plaintext attacks.
