Type-safe cryptography library offering secure random generation, common cryptographic operations (ciphers, digests, signatures), and multiple algorithm supports (AES, RSA, ECDSA, SHA) with various providers like OpenSSL and WebCrypto.
Surfaced from shared tags and platforms — no rankings paid for.
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.
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.
Detailed documentation is available on the project website, including the full provider support matrix.
