Crockford

class Crockford : Base32<Base32.Crockford.Config> (source)

Base32 encoding/decoding in accordance with the Crockford Spec

e.g.

val crockford = Base32.Crockford.Builder {
    isLenient(enable = true)
    encodeLowercase(enable = false)
    hyphen(interval = 5)
    check(symbol = '~')
    backFillBuffers(enable = true)
}

val text = "Hello World!"
val bytes = text.encodeToByteArray()
val encoded = bytes.encodeToString(crockford)
println(encoded) // 91JPR-V3F41-BPYWK-CCGGG~

// Alternatively, use the static implementation containing
// pre-configured settings, instead of creating your own.
val decoded = encoded.decodeToByteArray(Base32.Crockford).decodeToString()
assertEquals(text, decoded)
