For example, we want to hack an account：35hK24tcLEWcgNA4JxpvbkNkoAcDGqQPsP（12/7/2021 101451.70580859 BTC），

We have to try 1.1579209e+77 times to crack his private key.

Note that you don't have to try 2^256 times to crack an address' private key instead of the specific private key that was generated, but rather 2^160. The address is an encoding of a RIPEMD-160 hash result which is 160 bits (along with a network byte and a checksum). This means that for each address, there are around 2^96 valid private keys.

Data encrypted with the private key can only be decrypted with the public key, and data encrypted with the public key can only be decrypted with the private key.

Data encrypted with the private key cannot be decrypted by the public key in asymmetric encryption.

Understand, the public key only has the function of encryption. The private key only has the function of decryption
