    Anyone how to calculate pub key length
    What do you mean? How many characters/digits in a pubkey? Compressed, Uncompressed?
    compressed, starts with 02 or 03:
    Code:
    03284635D3127EA5E6AFFAD7213BED1BBB63535D9B2B4E22F63ED5093CB30FDAA5

    uncompressed:
    Code:
    04284635D3127EA5E6AFFAD7213BED1BBB63535D9B2B4E22F63ED5093CB30FDAA5F30279671068A413636A6116F3E43CFB2B476067C8CF6F801EE68E8C3E6D5F4F

    I know difference from compress and uncompress i want to know how to check what is lenght and which range belong example i saw here 64 is from 8:f if you explain
    Ok, it sounds like you are talking private key versus public key. Because 64 bits is from 8000000000000000:FFFFFFFFFFFFFFFF . The pubkeys are always the same length, just start with different number, 02, 03, 04 (uncompressed) and there is no way of knowing what range a pubkey lies in, unless you have the private key.
    I see but how then you set a range when search with kangaroo you guessing a range or you know something also what about hash160 is there some converter to pub key
