RSA

class RSA constructor(val publicKey: CryptoPublicKey.RSA, val privateKey: BigInteger, val prime1: BigInteger, val prime2: BigInteger, val prime1exponent: BigInteger, val prime2exponent: BigInteger, val crtCoefficient: BigInteger, val otherPrimeInfos: List<CryptoPrivateKey.RSA.PrimeInfo>?, val attributes: List<Asn1Element>? = null) : CryptoPrivateKey.Impl, CryptoPrivateKey.WithPublicKey<CryptoPublicKey.RSA>

PKCS#1 RSA Private key representation as per RFC 8017 augmented with optional attributes. Attributes are never PKCS#1 encoded, but are relevant when PKCS#8-encoding a private key.

Constructors

constructor(publicKey: CryptoPublicKey.RSA, privateKey: BigInteger, prime1: BigInteger, prime2: BigInteger, prime1exponent: BigInteger, prime2exponent: BigInteger, crtCoefficient: BigInteger, otherPrimeInfos: List<CryptoPrivateKey.RSA.PrimeInfo>?, attributes: List<Asn1Element>? = null)

Types

object Companion : PemDecodable<Asn1Sequence, CryptoPrivateKey.RSA>

object FromPKCS1 : Asn1Decodable<Asn1Sequence, CryptoPrivateKey.RSA>

data class PrimeInfo(val prime: BigInteger, val exponent: BigInteger, val coefficient: BigInteger) : Asn1Encodable<Asn1Sequence>

OtherPrimeInfos as per PKCS#1

Properties

val asPKCS1: PemEncodable<Asn1Sequence>

Encodes this private key into a PKCS#1-encoded private key

open val asPKCS8: PemEncodable<Asn1Sequence>

Encodes this private key into a PKCS#8-encoded private key. This is the default.

open override val attributes: List<Asn1Element>?

optional attributes relevant when PKCS#8-encoding a private key

canonicalPEMBoundary

open override val canonicalPEMBoundary: String

val crtCoefficient: BigInteger

qInv: the factors' CRT coefficient (q^(-1) mod p)

open override val oid: ObjectIdentifier

otherPrimeInfos

val otherPrimeInfos: List<CryptoPrivateKey.RSA.PrimeInfo>?

information about additional prime factors: triples (r_i, d_i, t_i) of prime factor, exponent, coefficient

val prime1: BigInteger

p: the first prime factor

val prime1exponent: BigInteger

dP: the first factor's CRT exponent

val prime2: BigInteger

q: the second prime factor

val prime2exponent: BigInteger

dQ: the second factor's CRT exponent

val privateKey: BigInteger

d: the private key such that d*e = 1 mod phi(n)

open override val publicKey: CryptoPublicKey.RSA

The CryptoPublicKey.RSA (n,e) matching this private key
