crack private key

How can we crack private key from public key?
Is it possible to do that or it is imposible?

Would like to know how to crack private key, can you teach me i would be so grateful what you feel

yes is it possible, but your computer must work for this 30, 50 mayby 100 years

You might as well read the entire dictionary, of all languages before you get a key opened.

Pretty impossible in your lifetime probably, so I suggest doing something else lol.

It's cryptographically and mathematically impossible with current technology.

unless you get a quantum computer atm with current technology its near impossible to do so. unless you somehow get access to a few of Googles Datacenters lol
