RSA4K

A RSA Cipher implementation for Kotlin/Java.

Usage

Import

Replace ${version} with the current version!

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

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

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

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

Example

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")
}
