OAEP

@SubclassOptInRequired(markerClass = [CryptographyProviderApi::class])

interface OAEP : RSA<RSA.OAEP.PublicKey, RSA.OAEP.PrivateKey, RSA.OAEP.KeyPair> (source)

RSA with Optimal Asymmetric Encryption Padding (OAEP) as defined in RFC 8017 Section 7.1.

Provides asymmetric encryption with support for associated data (labels).

val keys = provider.get(RSA.OAEP).keyPairGenerator().generateKey()
val ciphertext = keys.publicKey.encryptor().encrypt(plaintext)
val decrypted = keys.privateKey.decryptor().decrypt(ciphertext)

Types

Companion

object Companion : CryptographyAlgorithmId<RSA.OAEP>

KeyPair

@SubclassOptInRequired(markerClass = [CryptographyProviderApi::class])

interface KeyPair : RSA.KeyPair<RSA.OAEP.PublicKey, RSA.OAEP.PrivateKey>

PrivateKey

@SubclassOptInRequired(markerClass = [CryptographyProviderApi::class])

interface PrivateKey : RSA.PrivateKey<RSA.OAEP.PublicKey>

An RSA-OAEP private key that provides decryption via decryptor.

PublicKey

@SubclassOptInRequired(markerClass = [CryptographyProviderApi::class])

interface PublicKey : RSA.PublicKey

An RSA-OAEP public key that provides encryption via encryptor.

Properties

open override val id: CryptographyAlgorithmId<RSA.OAEP>

The typed identifier that uniquely distinguishes this algorithm and is used to look it up from a CryptographyProvider.

Functions

keyPairGenerator

abstract fun keyPairGenerator(keySize: BinarySize = 4096.bits, digest: CryptographyAlgorithmId<Digest> = SHA512, publicExponent: BigInt = 65537.toBigInt()): KeyGenerator<RSA.OAEP.KeyPair>

Returns a KeyGenerator that generates RSA key pairs with the given parameters.

privateKeyDecoder

abstract fun privateKeyDecoder(digest: CryptographyAlgorithmId<Digest>): Decoder<RSA.PrivateKey.Format, RSA.OAEP.PrivateKey>

Returns a Decoder that decodes RSA private keys for the given digest from the specified PrivateKey.Format.

publicKeyDecoder

abstract fun publicKeyDecoder(digest: CryptographyAlgorithmId<Digest>): Decoder<RSA.PublicKey.Format, RSA.OAEP.PublicKey>

Returns a Decoder that decodes RSA public keys for the given digest from the specified PublicKey.Format.
