Looking for a way to convert BTC addresses to HEX online

I need to change this BTC address into HEX format: 1PWo3JeB9jrGwfHDNpdGK54CRas7fsVzXU

Go through this links you will find what you are looking for. https://bitcointalk.org/index.php?topic=5413370.0 https://bitcointalk.org/index.php?topic=5477327.msg63304288#msg63304288

Thank you, could you do the conversion and write a response specifically about this BTC address? 1PWo3JeB9jrGwfHDNpdGK54CRas7fsVzXU

You mean reverse the bitcoin address to the public key's hex format? I don't believe that's doable. Same applies to the private key obviously. We could probably manage to help you more if you could describe what you're trying to achieve. Like what is it exactly you're trying to do with this hex? The above link is for people who have the private key's hex (the key that allows you to spend from the address). It's not going to be of any help here.

I need this because it needs to be placed in the test.txt file. This format is needed to run this program, with which I want to try my luck in opening puzzle number 71. https://github.com/Slait/Keyhuntbsgs/blob/main/BSGS_RU.md

There might be more simpler ways to do this, but this should be what you're looking: 0253f190353e719a74332b1037202e0477b73c663b9289fe0a65affc05b31cd919 0453f190353e719a74332b1037202e0477b73c663b9289fe0a65affc05b31cd9199113c1e290c21 8d03a9a029ace6b9377aa071bcecdb8f585b08defbf99009df6 - Take any transaction from this address, then click "details": https://mempool.space/tx/152210173d20a6945fe353d7cc4b02c431756a3009466dffd51723d55c6b4cc4 - Scroll down to ScriptSig (ASM) --> OP_PUSHBYTES_33 (That's your first HEX) - Use that in this compressor to get the second: https://iancoleman.io/bitcoin-key-compression/

I can't make a transaction because I don't have the private key; I'm just trying to find it. So the program I sent you a link to can only search for keys for wallets that have already had an outgoing transaction?

If I may get you right, you mean you don't have access to your private key? This is serious, Have you use brute forcing method and a software called Bitcoin Micro Collider, this software is use to find your lost private key. I haven't use it before or started it.

[/quote] this BTC address that I wrote is the address from puzzle number 71 and only the creator of the puzzle has the private key.

Just find tool or script that convert Base58 to HEX, such as this one https://learnmeabitcoin.com/technical/keys/base58/. That website also show step by step for the conversion process. Note that native SegWit address use Bech32 format, while Taproot adddress use Bech32m format. So you need to find different tool/script for those address format.

A little bit off topic, but this reminded me of this: Some time i ago need to convert transaction ID to hex. I had so much trouble finding it that i created a tool myself to do so: https://bitcoindata.science/bitcoin-raw-transaction-hex

Apologies. I mixed things up since the addresses look similar so the hexes I gave you above were for the addresses that sent the funds to the address you mentioned. And yes, from my understanding (and someone corrects me if I'm wrong) you can only get the HEX pubkey of an address, if it has at least one spent transaction (whether you were the one controlling the private key or not does not really matter). What are the hints for solving the puzzle exactly? did it mention anything about those pubkeys, or you just went your own way using this program?
