bitcoin-tool VS python-mnemonic

Download bitcoin-tool from https://github.com/matja/bitcoin-tool Compile it and follow the instructions

You can use bitcoin-tool to convert the key from Bitcoin WIF to hex, and then from hex to Litecoin WIF, then import into Electrum-ltc using p2wpkh-p2sh:T.... https://github.com/matja/bitcoin-tool

Obsolete, because it's not SegWit Try this: https://github.com/matja/bitcoin-tool

cd /usr/local/src curl https://github.com/matja/bitcoin-tool/archive/refs/heads/master.zip -O -L unzip master.zip cd bitcoin-tool-master make test <-- this compiles and tests the app cp -iv bitcoin-tool /usr/local/bin/

If you want to generate random keys, one at a time, and you have the knowledge and discipline to keep secure backup copies of all your keys, try bitcoin-tool https://github.com/matja/bitcoin-tool

There's a non-deterministic key generation tool, but only for people who understand how to make key-set backups, and when to make a new backup https://github.com/matja/bitcoin-tool Not suitable for engraving on metal

For many years, I have used bitcoin-tool for one-off Litecoin keys https://github.com/matja/bitcoin-tool

If you're using Linux, you might find this useful https://github.com/matja/bitcoin-tool

I use bitcoin-tool https://github.com/matja/bitcoin-tool But the same questions apply. How do you trust the C code in bitcoin-tool? I think if bitcoin-tool gives the same result as one of the javascript wallet generators, the developers of the different apps are unlikely to be conspiring

Yes. BIP39 defines a check word to ensure the previous words are correct. You can read the spec here: https://github.com/bitcoin/bips/blob/master/bip-0039.mediawiki

ColdCard follows the BIP-39 standard for encoding the wallet's seed as a series of 24 words (a.k.a. "seed menmonic", sometimes called a recovery phrase). If you followed the instructions you were given when initializing it and you've stored your seed mnemonic safely in the real world (not digitally where it can be more easily discovered), you're fine. In the event you lose or damage your ColdCard, you can initialize a new wallet--ANY wallet that follows the BIP-39 standard, which is pretty universal these days--and the wallet will regenerate the same private keysthat your original ColdCard did, in the same order.

... and BIP-39

Look-up "BIP32", "BIP39" and "BIP44", those will point you to documents describing precisely how seed phrases are converted into crypto keys.

i think bip39 is what you want to look up.
