i dont get the idea of range f6f543.
while all talk, range scanned to be empty
Lady, this has nothing to do with the prefix scan range. This is the HASH160 of a Bitcoin address.
And here is the correct sequence from private key to Bitcoin address:
Private Key
→ Public Key (via Elliptic Curve multiplication)
→ SHA-256 of the public key
→ RIPEMD-160 of the SHA-256 result (this gives the HASH160) ( this step )
they are talking about this as they want to get the public key for fast decryption and they will fail !
→ Add Network Byte (e.g., 0x00 for mainnet)
→ SHA-256 of that
→ SHA-256 again
→ Take first 4 bytes (checksum)
→ Append checksum to HASH160 + network byte
→ Base58Check encode
= Bitcoin Address
