Snippets

This folder is storing non-essential scripts (snippets, gists), which may however come in handy in a year or two.

These scripts do not need to have a high standard, but each of those should have a short description of what is it doing.

sign_tx.py

• signing of BTC transactions that can be spent with currently connected device
• need to specify the input UTXOs and the output address(es)
• generates a serialized transaction that can be then announced to the network

unify_test_files.py

• enforcing some readability practices in test files and possibly adding information about paths and addresses used
• need to specify all the files to be modified and optionally the path-to-address translation file
• rewrites the files in place, or just prints the intended changes when run with -c

monero_unused_functions

• Find functions from Monero cryptography that are not used.

eth_defs_unpack.py

• Unpacks the definitions from a definitions-sparse.zip that does not contain the Merkle proofs for space-saving. This format is not currently distributed.

recalc_optiga_for_emulator.py

• Takes a valid Infineon certificate from an Optiga and replaces its public key with a pubkey for private key 0x01000000..., so that the staging HSM can sign the resulting certificate.
