PKCS#1 RSA Private Keys as defined in RFC 8017 Appendix 1.2.

ASN.1 structure containing a serialized RSA private key:

RSAPrivateKey ::= SEQUENCE {
    version           Version,
    modulus           INTEGER,  -- n
    publicExponent    INTEGER,  -- e
    privateExponent   INTEGER,  -- d
    prime1            INTEGER,  -- p
    prime2            INTEGER,  -- q
    exponent1         INTEGER,  -- d mod (p-1)
    exponent2         INTEGER,  -- d mod (q-1)
    coefficient       INTEGER,  -- (inverse of q) mod p
    otherPrimeInfos   OtherPrimeInfos OPTIONAL
}

Note: the version field is selected automatically based on the absence or presence of the other_prime_infos field.

Fields

modulus: UintRef<'a>

n: RSA modulus.

public_exponent: UintRef<'a>

e: RSA public exponent.

private_exponent: UintRef<'a>

d: RSA private exponent.

prime1: UintRef<'a>

p: first prime factor of n.

prime2: UintRef<'a>

q: Second prime factor of n.

exponent1: UintRef<'a>

First exponent: d mod (p-1).

exponent2: UintRef<'a>

Second exponent: d mod (q-1).

coefficient: UintRef<'a>

CRT coefficient: (inverse of q) mod p.

other_prime_infos: Option<OtherPrimeInfos<'a>>

Additional primes r_3, …, r_u, in order, if this is a multi-prime RSA key (i.e. version is multi).
