Electrum 的自定義 Base43 - 尋找 2 路確定性十六進制轉換器

我正在尋找一個工具，適用於失憶的離線氣隙 Linux Live 主機

這將確定性地在原始十六進制和 Electrum 的自定義 Base43 格式之間進行雙向轉換，用於將 2900 多個字節的 BTC 交易數據放入 L-40 QR 碼中，

不需要我學習程式，拜託！

…來自 Electrum 的功能：

base_encode(tx_bytes, base=43)

base_decode(raw, base=43).hex()

…這個工具只解碼，不編碼

這似乎是一件有趣的事情。所以我創建了一個工具來做到這一點。

似乎還可以。

該程式碼非常簡單，幾乎任何人都可以閱讀並認為沒有任何惡意。我建議任何與加密貨幣相關的程序都應該在檢查程式碼後從原始碼編譯。go 編譯器可從 golang.org 免費下載。用於go build從原始碼創建程序。
