Data.ByteString.Bech32

The BIP0173 bech32 checksummed base32 encoding, with checksum verification.

Encoding

encode

Arguments

:: ByteString

base255-encoded human-readable part

-> ByteString

base255-encoded data part

-> Maybe ByteString

bech32-encoded bytestring

Encode a base255 human-readable part and input as bech32.

>>> let Just bech32 = encode "bc" "my string"
>>> bech32
"bc1d4ujqum5wf5kuecmu02w2"

Checksum

verify

Arguments

:: ByteString

bech32-encoded bytestring

-> Bool

Verify that a bech32 string has a valid checksum.

>>> verify "bc1d4ujqum5wf5kuecmu02w2"
True
>>> verify "bc1d4ujquw5wf5kuecmu02w2" -- s/m/w
False
