and i wonder how is that possible without knowing the private key from the beginning ??

All those address can be derived from the RMD hash of the address, example:

Address 13zb1hQbWVsc2S7ZTZnP2G4undNNpdh5so decoded in to Hexadecimal is:

0020d45a6a762535700ce9e0b216e31994335db8a5ee6612b2

But first byte for btc address is alway 00 and last 4 bytes are te checksum: ee6612b2

So the Real hash160 of the address 20d45a6a762535700ce9e0b216e31994335db8a5

Example with Dogecoin is almost the same, address D88gYxMEoumtZSJAC9mwa2EWfm6g3uocon

Decodes is 1e20d45a6a762535700ce9e0b216e31994335db8a50d861875

1e is the prefix for Doge, the checksum are the last 4 bytes: 0d861875

So the Real hash160 of the address 20d45a6a762535700ce9e0b216e31994335db8a5

So for almost all altcoin you only need the original rmd160 hash check the next image:

I recommend you to read Chapter 4. Keys, Addresses, Wallets
