multiple ripedmd160 from a private key.

[Andre_25]

Hi everyone.
Friends, I want to understand why the following happens.
with the private key "4efa6c238595b26de667cc9ba23beed9906d4a9a319e93578fd85994f4169bf7" I get 5 addresses:
1. 1L5Ey3hpFzQqcEugomCSaPFH8ca9N2W2RN
2. 1HXaZVhSNH79X59e1oVWSsz1rrVP4YYKon
3. 32BJnWpLNKAEGFLPvut8GLNNSGYryiAxzU
4. bc1qk49grr4ezfacr9xduav9777t885l4qm4gl9w99
5. bc1q3pq88knxfufvhwk3zls6feupq70r0ud4yesha25qtcj6v9na6rmssyrwku

If I try the first 3 of those addresses, in the link https://blockchain.info/es/addresstohash/XXX to obtain the hash, I get 3 different hashes.

1. d137b65522710266fcc2cd8f0c8daf6b963fb72b
2. b54a818eb9127b8194cde7585f7bcb39e9fa8375
3. 0559b8e6183c729d2b9a1d74b4ac46b3dafd54b2

why does that happen? Is there more than one "process" to generate the hash and why can it be different?
I understand and I consider the hash of the address number 1 as "main" but I am left wondering if, perhaps, with another private, it can have the hash 2 and with another private, it can have the hash 3, and these , in turn, you can access these 5 addresses in this example.

I ask, because I am considering using Altcrack and so I don't know if appending options 2 and 3 to the "wanted" list will work.
Thanks in what can help me

That's because different inputs will produce different hash values:

• 1. Is the HASH160 of the uncompressed public key of that private key.
• 2. Is the HASH160 of the compressed public key of that private key.
• 3. Is the HASH160 of the Redeem Script which is OP_0 <length> HASH160 of the compressed public key.

There is only one process to generate a hash, however there are many ways to generate an address.

Assuming you are not one of those guys wasting your time checking all private keys, when you want to "recover" something you should already have your address or at the very least have an idea about its type. For example an old wallet created in 2016 would be P2PKH using compressed public key.

How can you think? no way   


Ok, thank you both very much for the answers
