Kotlin js definitions and extensions for libsodium.js Meant to be used with gradle based kotlin javascript projects.
Add this to your dependencies:
dependencies {
implementation("com.bitbreeds.crypto","sodium-kt-ext","0.0.1")
}
Download the sodium.js file, and add it to your html like this.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
</body>
<script src="{YOUR_APPLICATION_NAME}.js"></script>
<script src="sodium.js" async></script>
</html>
Then to use libsodium, in the main method, do:
fun main() {
SodiumWindow.sodium = object :
SodiumHandler {
override var onload: (Sodium) -> dynamic = { sodium ->
val key = sodium.from_hex("724b092810ec86d7e35c9d067702b31ef90bc43a7b598626749914d6a3e033ed")
val nonce = sodium.randombytes_buf(sodium.crypto_secretbox_NONCEBYTES);
val cipherTxt = sodium.crypto_secretbox_easy(sodium.from_string("Hei hei!"),nonce,key)
console.log("Encrypted: $cipherTxt")
val resp = sodium.crypto_secretbox_open_easy(cipherTxt,nonce,key)
console.log("Decrypted: $resp")
}
}
}
An extension that allows creation of encrypted boxes with several recipients.
An example with 1 recipient:
fun main() {
SodiumWindow.sodium = object :
SodiumHandler {
override var onload: (Sodium) -> dynamic = { sodium ->
val keyPair = sodium.crypto_box_keypair()
val data = sodium.createMultiBox("Wat Wat Wat!", listOf(
Recipient(
keyPair.publicKey
)
))
console.log("Encrypted: $data")
val out = sodium.openMultiBox(data,keyPair.privateKey)
console.log("Decrypted: $out")
}
}
}
The definitions for libsodium goes in libsodium.kt, while
extensions that implement things on top of libsodium goes on their own
.kt file. See privatebox.kt
