cryptography-kotlin

A cryptography library for Kotlin Multiplatform, which wraps well-known future-proof platform-native solutions like OpenSSL, CryptoKit, WebCrypto or JCA with a type-safe uniform API, aligned defaults as well as tested for cross-compatibility between platforms.

Quick start

Add dependencies:

kotlin {
    sourceSets {
        commonMain.dependencies {
            implementation("dev.whyoleg.cryptography:cryptography-core:0.6.0")
            implementation("dev.whyoleg.cryptography:cryptography-provider-optimal:0.6.0")
        }
    }
}

Use the library:

// get a hasher
val sha = CryptographyProvider.Default.get(SHA512).hasher()
// hash a message
sha.hash("Kotlin is Awesome".encodeToByteArray())

For more, see the Getting Started guide and API Reference.
