Crate bech32 [−] [src]

Encoding and decoding Bech32 Bitcoin Segwit Addresses

Encoding and decoding for Bech32 strings and Bitcoin Segregated Witness addresses. 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 library contains bech32 utilities for generic encoding of Bech32 strings and wit_prog for converting witness programs to Bitcoin addresses and back.

Examples

use bech32::wit_prog::WitnessProgram;
 
let witness_program = WitnessProgram {
    version: 0,
    program: vec![
                0x00, 0x00, 0x00, 0xc4, 0xa5, 0xca, 0xd4, 0x62, 
                0x21, 0xb2, 0xa1, 0x87, 0x90, 0x5e, 0x52, 0x66, 
                0x36, 0x2b, 0x99, 0xd5, 0xe9, 0x1c, 0x6c, 0xe2, 
                0x4d, 0x16, 0x5d, 0xab, 0x93, 0xe8, 0x64, 0x33]
};
 
let enc_result = witness_program.to_address("tb".to_string());
assert_eq!(enc_result.unwrap(), 
    "tb1qqqqqp399et2xygdj5xreqhjjvcmzhxw4aywxecjdzew6hylgvsesrxh6hy".to_string());
