multibase

This is a port of Protocol Labs' Kotlin/JVM multibase implementation to Kotlin multiplatform with significant help from Matthew Nelson's awesome encoding library and Uglješa Jovanović's KMP bignum library.

This project includes the original Protocol Labs repository as a git submodule for it's test vectors, but does not incorporate any code form it in releases.

multi²–_base supports the following multibase encodings:

• BASE10

• BASE16

• BASE16_UPPER

• BASE32

• BASE32_UPPER

• BASE32_PAD

• BASE32_PAD_UPPER

• BASE32_HEX

• BASE32_HEX_UPPER

• BASE32_HEX_PAD

• BASE32_HEX_PAD_UPPER

• BASE58_FLICKR

• BASE58_BTC

• BASE64

• BASE64_URL

• BASE64_PAD

• BASE64_URL_PAD

Using in your Projects

This library is available at maven central.

Gradle

dependencies {
    implementation("at.asitplus:multibase:$version")
}

Note: This library exposes Matthew Nelson's Base64, Base32, and Base16 encoders as API dependency!

API

Simply MultiBase.decode(from_multibase_string) or MutltiBase.encode(Base.<desired>, any_byte_array) to a multibase string or use the extension functions:

• multibase_string.multibaseDecode()

• byteArray.multibaseEncode(Base.<desired>)

Note: Base10 and Base58 don't perform well. Only use those on small (<4KiB) data.
