Type-safe Multiplatform cryptography library for Kotlin
```kotlin
CryptographyProvider.Default
.get(SHA512)
.hasher()
.hash("Kotlin is Awesome".encodeToByteArray())
```
Detailed documentation can be found on
[project website](https://whyoleg.github.io/cryptography-kotlin/) as well as in
[API reference](https://whyoleg.github.io/cryptography-kotlin/api/)
## Overview
cryptography-kotlin provides multiplatform API which consists of multiple components:
* [Secure random][Secure random] with [kotlin.Random][kotlin.Random] like API which can be used independently of other modules
* common API to use different cryptography operations,
like [ciphers][ciphers], [digests][digests], [signatures][signatures], [key derivation][key derivation], [Key agreement][Key agreement]
* multiple algorithms definitions, like [AES][AES], [RSA][RSA], [ECDSA][ECDSA], [ECDH][ECDH], [SHA][SHA256], [HMAC][HMAC]
and [PBKDF2][PBKDF2]
* multiple cryptography [providers][providers], like [OpenSSL][OpenSSL], [WebCrypto][WebCrypto] and [JDK][JDK]
The library doesn't implement any cryptography algorithm on its own, but wraps well-known future-proof solutions
like [OpenSSL 3.x](https://www.openssl.org), [WebCrypto](https://developer.mozilla.org/en-US/docs/Web/API/Web_Crypto_API)
or [JCA](https://docs.oracle.com/en/java/javase/17/security/java-cryptography-architecture-jca-reference-guide.html)
with type-safe multiplatform API providing uniform experience with aligned default behavior,
and same expected results using identical parameters while allowing to use platform-specific capabilities.
For supported algorithms, primitives and targets, please consult [Providers documentation][providers]
## Using in your projects
Make sure that you use Kotlin 2.0.20+.
Using an earlier Kotlin version could still work, but not tested.
Additionally, it's possible to use [BOM][BOM] or [Gradle version catalog][Gradle version catalog] to add dependencies easier.
The library is published to Maven Central, so make sure, that it’s added to repositories.
```kotlin
kotlin {
sourceSets {
commonMain.dependencies {
implementation("dev.whyoleg.cryptography:cryptography-core:0.4.0")
}
// or androidMain
jvmMain.dependencies {
implementation("dev.whyoleg.cryptography:cryptography-provider-jdk:0.4.0")
}
appleMain.dependencies {
implementation("dev.whyoleg.cryptography:cryptography-provider-apple:0.4.0")
// or openssl3 provider with better algorithms coverage and other native targets support
// implementation("dev.whyoleg.cryptography:cryptography-provider-openssl3-prebuilt:0.4.0")
}
wasmJsMain.dependencies {
implementation("dev.whyoleg.cryptography:cryptography-provider-webcrypto:0.4.0")
}
}
}
```
Snapshots of the development version are available in Sonatype's snapshot repository.
```kotlin
repositories {
maven("https://s01.oss.sonatype.org/content/repositories/snapshots/")
}
dependencies {
implementation("dev.whyoleg.cryptography:cryptography-core:0.4.1-SNAPSHOT")
}
```
