Usage

Import

Replace ${version} with the current version!

Gradle KTS

repositories {
    maven("https://jitpack.io")
}

dependencies {
    implementation("com.github.Lyzev:RSA4K:${version}")
}

Gradle Groovy

repositories {
	maven { url 'https://jitpack.io' }
}

dependencies {
    implementation 'com.github.Lyzev:RSA4K:${version}'
}

Maven


    
        jitpack.io
        https://jitpack.io
    



    
        com.github.Lyzev
        RSA4K
        ${version}

Raw Jar

Go to the release page.
Download RSA4K-${version}-all.jar.
Add the jar to your classpath.

Example

${keys.first.exp}") println("public modulus -> ${keys.first.mod}") println("private exponent -> ${keys.second.exp}") println("private modulus -> ${keys.second.mod}") println("encrypted -> $encrypted") println("decrypted -> $decrypted") }">

fun main() {
    val keys = RSAKeyFactory.genKeyPair()
    val cipher = RSA(keys.first, keys.second)
    val msg = "Test"

    val encrypted = cipher.encrypt(msg.encodeToByteArray())
    val decrypted = String(cipher.decrypt(encrypted!!))

    println("public exponent -> ${keys.first.exp}")
    println("public modulus -> ${keys.first.mod}")
    println("private exponent -> ${keys.second.exp}")
    println("private modulus -> ${keys.second.mod}")
    println("encrypted -> $encrypted")
    println("decrypted -> $decrypted")
}
