Bech32 Rust

Rust implementation of the Bech32 encoding format described in BIP-0173. You can find some usage examples in the documentation.

Bitcoin-specific address encoding is handled by the bitcoin-bech32 crate.

lib.rs:

Encoding and decoding Bech32 format

Bech32 is a 5-bit (base-32) encoding scheme that produces strings that comprise a human-readable part, a separator, a data part, and a checksum. The encoding implements a BCH code that guarantees error detection of up to four characters with less than 1 in 1 billion chance of failing to detect more errors.

The Bech32 encoding was originally formulated in BIP-0173

Examples

use bech32::{self, FromBase32, ToBase32};

let encoded = bech32::encode("bech32", vec![0x00, 0x01, 0x02].to_base32()).unwrap();
assert_eq!(encoded, "bech321qqqsyrhqy2a".to_string());

let (hrp, data) = bech32::decode(&encoded).unwrap();
assert_eq!(hrp, "bech32");
assert_eq!(Vec::<u8>::from_base32(&data).unwrap(), vec![0x00, 0x01, 0x02]);
