Modern cryptographic library enabling secure key generation, encryption, and digital signatures. Integrates platform-specific security features and offers a unified API for cryptographic operations.
A modern Kotlin Multiplatform cryptographic library for secure key generation, encryption, and digital signatures across Android and iOS platforms. This library provides a unified API for cryptographic operations while leveraging platform-specific security features like Android Keystore and iOS Keychain.

This library provides cryptographic functionality for Kotlin Multiplatform applications:
The library provides a unified interface for cryptographic operations across platforms:
// Common interface (shared-domain/src/commonMain/kotlin/dev/sdkforge/crypto/domain/KeyGenerator.kt)
expect object KeyGenerator {
suspend fun generate(
algorithm: KeyAlgorithm,
identifier: String,
keySize: Int,
): KeyPair
}
// Supported algorithms
enum class KeyAlgorithm {
RSA,
EC,
}
// Generate a 2048-bit RSA key pair
val keyPair = KeyGenerator.generate(
algorithm = KeyAlgorithm.RSA,
identifier = "my-rsa-key",
keySize = 2048
)
println("Public Key: ${keyPair.publicKey.algorithm}")
println("Private Key: ${keyPair.privateKey.algorithm}")
// Generate an EC key pair (typically 256-bit)
val ecKeyPair = KeyGenerator.generate(
algorithm = KeyAlgorithm.EC,
identifier = "my-ec-key",
keySize = 256
)
The library automatically uses platform-specific security features:
