Internal function that computes the Bech32 checksum.

swh.alter.bech32.bech32_hrp_expand(hrp: str) List[int][source]#

Expand the HRP into values for checksum computation.

swh.alter.bech32.bech32_verify_checksum(hrp: str, data: List[int]) Optional[Encoding][source]#

Verify a checksum given HRP and converted data characters.

swh.alter.bech32.bech32_create_checksum(hrp: str, data: List[int], spec: Encoding) List[int][source]#

Compute the checksum values given HRP and data.

swh.alter.bech32.bech32_encode(hrp: str, data: List[int], spec: Encoding) str[source]#

Compute a Bech32 string given HRP and data values.

swh.alter.bech32.bech32_decode(bech: str) Tuple[str, List[int], Encoding][source]#

Validate a Bech32/Bech32m string, and determine HRP and data.
