Hello everyone,

I want to know how I can find the public key (compressed or uncompressed) of any address, because i see there are too many addresses but they didn't have the public key so i check them blockchair.com and other explorer but they also didn't show the public key.

Here is the sample address: 1N45DoSuhiNi5dCqMTpC2k3tfSaHEw1uKk

Is there any way How to find the first 35 digits of bitcoin private key? anyone know the calculation ?
