Base encoding / decoding of any given alphabet using bitcoin style leading zero compression.
This is an rewrite of the multi base codec library base-x from javascript to Swift.
Add the following to your Cartfile
github "uport-project/SwiftBaseX"To encode a Data object we include the hexEncodedString() and base58EncodedString() methods as an extension
import SwiftBaseX
let data: Data = ....
let encoded:String = data.hexEncodedString()For cases where you need a full hex string without leading zero compression we've also included the following variation.
let encoded:String = data.fullHexEncodedString()Hex strings are commonly prefixed with 0x in the crypto world. 0x prefixes are automatically stripped when decoding. To automatically add 0x during hex encoding pass in true to either hexEncodedString() or fullHexEncodedString().
For String we include the decodeHex() and decodeBase58() methods as an extension.
import SwiftBaseX
let decoded: Data = "Cn8eVZg".decodeBase58()For cases where you need to decode a full hex string without leading zero compression we've also included the following variation.
let encoded:String = data.decodeFullHex()
