secure-random

Kotlin Multiplatform library for obtaining cryptographically secure random data from the system.

NOTE: For Jvm, SecureRandom extends java.security.SecureRandom for interoperability.

The Linux/AndroidNative implementation was heavily inspired by
rust-random/getrandom.

Example Usages

fun main() {
    val sRandom = SecureRandom()

    val bytes: ByteArray = try {
        sRandom.nextBytesOf(count = 20)
    } catch (e: SecRandomCopyException) {
        e.printStackTrace()
        return
    }

    println(bytes.toList())
}

fun main() {
    val sRandom = SecureRandom()
    val bytes = ByteArray(20)
    
    try {
        sRandom.nextBytesCopyTo(bytes)
    } catch (e: SecRandomCopyException) {
        e.printStackTrace()
        return
    }

    println(bytes.toList())
}

Get Started

The best way to keep KotlinCrypto dependencies up to date is by using the version-catalog. Alternatively, see below.

// build.gradle.kts
dependencies {
    implementation("org.kotlincrypto:secure-random:0.3.1")
}

// build.gradle
dependencies {
    implementation "org.kotlincrypto:secure-random:0.3.1"
}
