Module cryptography-core

Provides multiplatform API to build, get and use cryptography primitives

Core entities:

• CryptographyProvider provides a way to get specific CryptographyAlgorithm by its id
• CryptographyProvider.Default is the default provider which is just a link to the first registered provider. After adding dependency to provider (like openssl3) it will be automatically registered as default
• inheritors of CryptographyAlgorithm (like f.e. AES) provides access to operations (like f.e. cipher)

Example

CryptographyProvider.Default
    .get(SHA512)
    .hasher()
    .hash("Kotlin is Awesome".encodeToByteArray())

Using in your projects

dependencies {
    implementation("dev.whyoleg.cryptography:cryptography-core:0.4.0")
}

Package dev.whyoleg.cryptography

Provides core primitives for creating and accessing CryptographyAlgorithm and CryptographyProvider

Package dev.whyoleg.cryptography.algorithms

Provides common algorithms:

• digests (e.g SHA256 and SHA512)
• symmetric ciphers (AES)
• asymmetric encryption and signature (RSA and ECDSA)
• MAC (HMAC)
• Key derivation (PBKDF2 and HKDF)
• Key agreement (ECDH)

Package dev.whyoleg.cryptography.operations

Provides APIs to perform cryptography operations:

• hashing
• encryption/decryption and Authenticated encryption/decryption
• signature verification and generation
• secret derivation (KDF/PRF) and shared secret derivation (Key agreement)

Package dev.whyoleg.cryptography.materials.key

Provides API for working with keys: encoding, decoding and generation
