Added

  • Added bech32 command-line for easy conversions in the console.

    Usage: bech32 [PREFIX]
  Convert to and from bech32 strings. Data are read from standard input.

Available options:
  -h,--help                Show this help text
  PREFIX                   An optional human-readable prefix (e.g. 'addr').
                             - When provided, the input text is decoded from various encoding formats and re-encoded to bech32 using the given prefix.
                             - When omitted, the input text is decoded from bech32 to base16.

Supported encoding formats: Base16, Bech32 & Base58.

Examples:
  To Bech32:
    $ bech32 base16_ <<< 706174617465
    base16_1wpshgct5v5r5mxh0

    $ bech32 base58_ <<< Ae2tdPwUPEYy
    base58_1p58rejhd9592uusa8pzj2

    $ bech32 new_prefix <<< old_prefix1wpshgcg2s33x3
