Base58Check

public struct Base58Check

A set of Base58Check coding methods.

// Encode bytes to address
let address = Base58Check.encode([versionByte] + pubkeyHash)

// Decode address to bytes
guard let payload = Base58Check.decode(address) else {
    // Invalid checksum or Base58 coding
    throw SomeError()
}
let versionByte = payload[0]
let pubkeyHash = payload.dropFirst()

  • Encodes the data to Base58Check encoded string

    Puts checksum bytes to the original data and then, encode the combined data to Base58 string.

    let address = Base58Check.encode([versionByte] + pubkeyHash)

    Declaration

    Swift

    public static func encode(_ payload: Data) -> String

  • Decode the Base58 encoded String value to original payload

    First validate if checksum bytes are the first 4 bytes of the sha256(sha256(payload)). If it’s valid, returns the original payload.

    let payload = Base58Check.decode(base58checkText)

    Declaration

    Swift

    public static func decode(_ string: String) -> Data?

  • Base58 encode an array of bytes and add the supplied prefix

    Declaration

    Swift

    public static func encode(message: [UInt8], prefix: [UInt8]) -> String

  • Base58 decode a message, removing the supplied prefix

    Declaration

    Swift

    public static func decode(string: String, prefix: [UInt8]) -> [UInt8]?

  • Base58 encode an array of bytes and add the appropriate prefix base on the ellipticalCurve

    Declaration

    Swift

    public static func encode(message: [UInt8], ellipticalCurve: EllipticalCurve) -> String
