Bitcoin mind wallet
I wrote this demo to mess around with brain wallets https://github.com/timchurchard/twopasswords it can generate a seed from a passphrase. And it can generate a wallet from two passphrases. You can specify the number of iterations for the process and picking large numbers can make it take real time, reducing the risk of brute force. I do not recommend using this. I wrote it for fun and to demonstrate the idea.

My first bitcoin-related project: brainseed
Looks good. I wrote a similar thing for fun https://github.com/timchurchard/twopasswords it can make a seed from a password. And it accepts a second password to use as bip39 password. The user can specify the number of iterations. And it has a balance check & paper wallet example in a PR. I have a folded paper in my wallet with two passwords on that lead to 1.5M Sats just because.

What is your view on brain wallets.
I wrote a demo to mess around with turning passwords into seeds & addresses: https://github.com/timchurchard/twopasswords -- This demo takes one password and a number of iterations to make a seed. You can specify a second password which will be used for bip39, if you want to make an address. You can specify numbers of iterations that take real time to work out. 21,000,000 for example takes about 10s on my machine.

Keep it on-topic
And I wrote this https://github.com/timchurchard/twopasswords demo to explore making "brain" wallets. I've got this idea like: "What if I went to prison and could store nothing"..."how would I keep my Bitcoin". I'm thinking I may make an app that instantly forgets. So you enter your two passwords and the phone takes a few seconds of CPU work to hash them 21,000,000 times to produce the entropy for bip39. Then works like a normal wallet with send/receive. Once the app exits nothing is stored. A burner bitcoin wallet.

Generating and Working With ScriptPubKeys in Bitcoin Transactions
As mentioned previously, ScriptPubKeys are scripts that embody the locking conditions of bitcoins in a Bitcoin transaction. They are a crucial element of a Bitcoin transaction that specifies the requirements that must be met before an unspent transaction output (UTXO) is used. The ScriptPubKey, combined with the Amount, creates an output of a Bitcoin transaction. Like every other script, ScriptPubKeys are made up of operators and data. During the encoding of a transaction, both data and the operands are represented in hexadecimal format. You can find the hex representation for all operands used in Bitcoin Scripts here.
