sigil bitcoin encoding

Encode a bytevector as lowercase hexadecimal text.

Decode an even-length hexadecimal string into a bytevector. Raises an error for odd-length input or invalid hex characters.

Encode a bytevector with Bitcoin's Base58 alphabet. Leading zero bytes are preserved as leading `1` characters.

Decode a Bitcoin Base58 string into a bytevector. Raises an error if the string contains characters outside the Bitcoin Base58 alphabet.

Encode a Base58Check payload with a one-byte version prefix. The checksum is the first four bytes of HASH256(version || payload).

Decode a Base58Check string. Returns `(version . payload)` and raises an error on checksum failure.

Encode a Bech32 string using the BIP173 checksum constant. `hrp` is the human-readable part and `data` is a bytevector of 5-bit values.

Decode a Bech32 string. Returns `(hrp . data)` where `data` excludes the six checksum values.

Encode a Bech32m string using the BIP350 checksum constant.

Decode a Bech32m string. Returns `(hrp . data)` where `data` excludes the six checksum values.

Encode a native SegWit address for a witness version and program. Version 0 uses Bech32. Versions 1 through 16 use Bech32m.

Decode a native SegWit address. Returns `(hrp version . program)` and validates the checksum variant required by the witness version.
