RSAKey Type

Contains the typical parameters for the RSA algorithm.

Remarks

This type is made up of fields that represent the private and public key parameters used by the RSA algorithm.

RSA Keys

A RSA key is made up of a number of individual parameters.

The public key consists of the following parameters:

The class also includes the PublicKey property which holds the PEM formatted public key for ease of use. This is helpful if you are in control of both sides of the encryption/signing and decryption/signature verification process. When sending the public key to a recipient note that not all implementations will support using the PEM formatted value in PublicKey in which case the individual parameters must be sent.

The private key may be represented in one of two ways. Both are mathematically equivalent. Private key format 1:

Private key format 2 is simpler but has decreased performance when decrypting and signing. This format is: The class also include the PrivateKey property which holds the PEM formatted private key for ease of use. This is helpful for storing the private key more easily.

Fields

dB
Data

Represents the D parameter for the RSA algorithm.

d
String

Represents the D parameter for the RSA algorithm.

dpB
Data

Represents the DP parameter for the RSA algorithm.

dp
String

Represents the DP parameter for the RSA algorithm.

dqB
Data

Represents the DQ parameter for the RSA algorithm.

dq
String

Represents the DQ parameter for the RSA algorithm.

exponentB
Data

Represents the Exponent parameter for the RSA algorithm.

exponent
String

Represents the Exponent parameter for the RSA algorithm.

inverseQB
Data

Represents the InverseQ parameter for the RSA algorithm. This parameter is optional and is automatically calculated as necessary.

inverseQ
String

Represents the InverseQ parameter for the RSA algorithm. This parameter is optional and is automatically calculated as necessary.

modulusB
Data

Represents the Modulus parameter for the RSA algorithm.

modulus
String

Represents the Modulus parameter for the RSA algorithm.

pB
Data

Represents the P parameter for the RSA algorithm.

p
String

Represents the P parameter for the RSA algorithm.

privateKey
String

This property is a PEM formatted private key. The purpose of this property is to allow easier management of the private key parameters by using only a single value.

publicKey
String

This property is a PEM formatted public key. The purpose of this property is to allow easier management of the public key parameters by using only a single value.

qB
Data

Represents the Q parameter for the RSA algorithm.

q
String

Represents the Q parameter for the RSA algorithm.

Constructors

public init()

The default constructor creates a new RSAKey instance but does not assign a public or private key.

public init(modulus: Data, exponent: Data)

The public key constructor assigns an existing public key.

public init(modulus: Data, d: Data, p: Data, q: Data, dP: Data, dQ: Data)

The private key constructor assigns an existing private key. Any valid combination of parameters representing a private key may be supplied. See the description at the top of this page for details on RSA private key formats.
