I have a private key and I want to store a paper version of it. I would like to split it in 2 equal parts (first 32 numbers and last 32 numbers) and store them in 2 different locations. Let's assume I'm 100% sure no one can access both parts, but it's possible that someone can steal one of them.
How much am I compromised?
To explain the question: I understand the attacker needs to guess only 32 hexadecimal numbers instead of 64 to complete the private key. Is that so much easier than guessing 64? Does this seriously undermine the security of my account? And is there something I'm missing that makes it even easier than guessing the remaining 32 numbers (ex: given the first 32 numbers only a possible subset of all remaining 32 numbers is possible due to some constraint)?
