Data.ByteString.Bech32m

The BIP350 bech32m checksummed base32 encoding, with checksum verification.

Encoding

encode

Arguments

:: ByteString

base255-encoded human-readable part

-> ByteString

base255-encoded data part

-> Maybe ByteString

bech32m-encoded bytestring

Encode a base255 human-readable part and input as bech32m.

>>> let Just bech32m = encode "bc" "my string"
>>> bech32m
"bc1d4ujqum5wf5kuecwqlxtg"

Checksum

verify

Arguments

:: ByteString

bech32m-encoded bytestring

-> Bool

Verify that a bech32m string has a valid checksum.

>>> verify "bc1d4ujqum5wf5kuecwqlxtg"
True
>>> verify "bc1d4ujquw5wf5kuecwqlxtg" -- s/m/w
False
