RAW

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

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

Raw RSA without padding (textbook RSA).

Performs the raw RSA primitive without any padding scheme.

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

Unsafe for general use — prefer OAEP for encryption and PSS for signatures.

Types

Companion

object Companion : CryptographyAlgorithmId<RSA.RAW>

KeyPair

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

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

PrivateKey

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

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

A raw RSA private key that provides decryption via decryptor.

PublicKey

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

interface PublicKey : RSA.PublicKey

A raw RSA public key that provides encryption via encryptor.

Properties

open override val id: CryptographyAlgorithmId<RSA.RAW>

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.RAW.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.RAW.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.RAW.PublicKey>

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