This is an implementation of Base58 encode/decode check/uncheck algorithm.

Example:

import Base58

/// Encoding to Base58
/// 1. convert string to bytes (utf8 format)
let bytes = "Hello, World!".makeBytes()
/// 2. encode bytes using base58 algorithm
let encodedBytes = Base58.encode(bytes)
/// 3. converting bytes back to string
let encodedString = try String(encoded) // "72k1xXWG59fYdzSNoA"


/// Decoding from Base58
/// 1. convert string to bytes (utf8 format)
let bytes = "72k1xXWG59fYdzSNoA".makeBytes()
/// 2. decode bytes using base58 algorithm
let decodedBytes = try Base58.decode(bytes)
/// 3. converting bytes back to string
let decodedString = try String(encoded) // "Hello, World!"


/// Encoding to Base58Check
/// 1. convert string to bytes (utf8 format)
let bytes = "Hello, World!".makeBytes()
/// 2. encode bytes using base58Check algorithm
let encodedBytes = Base58.check(bytes)
/// 3. converting bytes back to string
let encodedString = try String(encoded) // "gTazoqFvnegwaKM8v2MZsVw"


/// Decoding from Base58Check
/// 1. convert string to bytes (utf8 format)
let bytes = "gTazoqFvnegwaKM8v2MZsVw".makeBytes()
/// 2. decode bytes using base58Check algorithm
let decodedBytes = try Base58.uncheck(bytes)
/// 3. converting bytes back to string
let decodedString = try String(encoded) // "Hello, World!"

Importing Base58:

To include Base58 in your project, you need to add the following to the dependencies attribute defined in your Package.swift file.

dependencies: [
  .package(url: "https://github.com/alja7dali/swift-base58.git", from: "1.0.0")
]
