The compression can only applied to the public key. Good explanation here: # https://www.reddit.com/r/Bitcoin/comments/2u0tin/why_are_private_keys_called_compressed_if_theyre/ # # We are now generating a random private key with pybitcointools library. # IMPORTANT: I CANNOT GUARANTEE THAT THE FOLLOWING GENERATED RANDOM KEY IS SECURE. I CAN ASSUME THOUGH. # # PLEASE USE IT ONLY FOR THIS DEMO. FOR YOUR REAL LIFE BITCOIN WALLETS, USE A PROPER # OFFLINE WALLET APP. # private_key_hex = pybitcointools.random_key() # Each cryptocurrency Private Key has their own prefix version number (Bitcoin= 0x80, Litecoin=0xB0, etc). # Prepend this version number in front of the private_key_hex value. # The prefix version number is always 1 byte in size and the private_key_hex is 32 bytes. # The private_key_with_version value is always (1+32=) 33 bytes or 66 characters long. private_key_with_version = '80' + private_key_hex # WIF ADDRESS FOR UNCOMPRESSED PUBLIC KEY # # The Private Key Wallet Import Format (WIF) is just the Private Key # with metadata and encoded with Base58 (check generate_addresses.wif_private_key # function for details). # # Sometimes The WIF key is referred as "compressed or uncompressed WIF". This is confusing because # the actual private key or derived WIF is never compressed. When people mention "compressed or uncompressed WIF"
