Implements RSA public-key cryptography to encrypt/decrypt and sign/verify messages.

Syntax

IPWorksEncrypt.RSA

Remarks

The RSA class implements RSA public-key cryptography to encrypt/decrypt messages and sign/verify hash signatures.

To begin you must either specify an existing key or create a new key. Existing private keys may be specified by setting Key. To create a new key call CreateKey. Alternatively an existing certificate may be specified by setting Certificate

Signing

To sign data first set Key or Certificate. Specify the input data using InputFile or InputMessage. Next call Sign. The class will populate HashValue and HashSignature. After calling Sign the public key must be sent to the recipient along with HashSignature.

Encrypting

To encrypt data set RecipientKey or RecipientCert. Specify the input data using InputFile or InputMessage. Next call Encrypt. The class will populate OutputMessage, or write to the file specified by OutputFile.

Signature Verification

To verify a signature specify the input data using InputFile or InputMessage. Set SignerKey or SignerCert. Next set HashSignature and call VerifySignature. The VerifySignature method will return True if the signature was successfully verified.

Decrypting

To decrypt data first set Key or Certificate. Specify the input data using InputFile or InputMessage. Next call Decrypt. The class will populate OutputMessage, or write to the file specified by OutputFile.

Input and Output Properties

The class will determine the source and destination of the input and output based on which properties are set.

The order in which the input properties are checked is as follows:

When a valid source is found, the search stops. The order in which the output properties are checked is as follows:

RSA Keys

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

The public key consists of the following parameters:

  • KeyModulus
  • KeyExponent

The class also includes the KeyPublicKey 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 KeyPublicKey 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:

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

Default Value

False

Remarks

This property specifies a certificate for signature verification.

This may be set instead of SignerKey. This allows a Certificate object to be used instead of a RSAKey object. This certificate is used when calling VerifySignature.

If both this property and SignerKey are specified, SignerKey will be used and this property will be ignored.

SignerKey Property (RSA Module)

The public key used to verify the signature.

Syntax

public var signerKey: RSAKey {
  get {...}
  set {...}
}


@property (nonatomic,readwrite,assign,getter=signerKeyExponent,setter=setSignerKeyExponent:) NSString* signerKeyExponent;

- (NSString*)signerKeyExponent;
- (void)setSignerKeyExponent :(NSString*)newSignerKeyExponent;

- (NSData*)signerKeyModulusB;
- (void)setSignerKeyModulusB :(NSData*)newSignerKeyModulus;
@property (nonatomic,readwrite,assign,getter=signerKeyPublicKey,setter=setSignerKeyPublicKey:) NSString* signerKeyPublicKey;

- (NSString*)signerKeyPublicKey;
- (void)setSignerKeyPublicKey :(NSString*)newSignerKeyPublicKey;

Default Value

False

Remarks

This property specifies the public key used to verify the signature. This public key corresponds to the private key used when creating the signature. This must be set before calling VerifySignature. Alternatively, a certificate may be specified by setting SignerCert

RSA Keys

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

The public key consists of the following parameters:

  • KeyModulus
  • KeyExponent

The class also includes the KeyPublicKey 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 KeyPublicKey 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:

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

UseHex Property (RSA Module)

Whether input or output is hex encoded.

Syntax

public var useHex: Bool {
  get {...}
  set {...}
}


@property (nonatomic,readwrite,assign,getter=useHex,setter=setUseHex:) BOOL useHex;

- (BOOL)useHex;
- (void)setUseHex :(BOOL)newUseHex;

Default Value

False

Remarks

This property specifies whether the encrypted data, HashValue, and HashSignature are hex encoded.

If set to True, when Encrypt is called the class will perform the encryption as normal and then hex encode the output. OutputMessage or OutputFile will hold hex encoded data.

If set to True, when Decrypt is called the class will expect InputMessage or InputFile to hold hex encoded data. The class will then hex decode the data and perform decryption as normal.

If set to True, when Sign is called the class will compute the hash for the specified file and populate HashValue with the hex encoded hash value. It will then create the hash signature and populate HashSignature with the hex encoded hash signature value. If HashValue is specified directly, it must be a hex encoded value.

If set to True, when VerifySignature is called the class will compute the hash value for the specified file and populate HashValue with the hex encoded hash value. It will then hex decode HashSignature and verify the signature. HashSignature must hold a hex encoded value. If HashValue is specified directly, it must be a hex encoded value.

UseOAEP Property (RSA Module)

Whether to use Optimal Asymmetric Encryption Padding (OAEP).

Syntax

public var useOAEP: Bool {
  get {...}
  set {...}
}


@property (nonatomic,readwrite,assign,getter=useOAEP,setter=setUseOAEP:) BOOL useOAEP;

- (BOOL)useOAEP;
- (void)setUseOAEP :(BOOL)newUseOAEP;

Default Value

False

Remarks

Note: When set to True the HashAlgorithm is also applicable when calling Encrypt and Decrypt.

UsePSS Property (RSA Module)

Whether to use RSA-PSS during signing and verification.

Syntax

public var usePSS: Bool {
  get {...}
  set {...}
}


@property (nonatomic,readwrite,assign,getter=usePSS,setter=setUsePSS:) BOOL usePSS;

- (BOOL)usePSS;
- (void)setUsePSS :(BOOL)newUsePSS;

Default Value

False

Remarks

This property specifies whether RSA-PSS will be used when signing and verifying messages. The default value is False.

Config Method (RSA Module)

Sets or retrieves a configuration setting.

Syntax

public func config(configurationString: String) throws -> String

- (NSString*)config:(NSString*)configurationString;

Remarks

Config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

CreateKey Method (RSA Module)

Creates a new key.

Syntax

public func createKey() throws -> Void

- (void)createKey;

Remarks

This method creates a new public and private key.

When calling CreateKey the Key property is populated with a new private and public key.

RSA Keys

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

The public key consists of the following parameters:

  • KeyModulus
  • KeyExponent

The class also includes the KeyPublicKey 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 KeyPublicKey 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:

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

Decrypt Method (RSA Module)

- (void)decrypt;

Remarks

This method decrypts the input data using the private key specified in Key. Alternatively, a certificate may be specified by setting Certificate.

Input and Output Properties

The class will determine the source and destination of the input and output based on which properties are set.

The order in which the input properties are checked is as follows:

When a valid source is found, the search stops. The order in which the output properties are checked is as follows:

Key Size and the Maximum Length of Data

RSA has an upper limit to the amount of data that can be encrypted or decrypted, also known as message length. This can typically be calculated as the size of the key minus the size of the RSA header and padding.

When not using OAEP, the following formula and table can be referenced. (RSA Key Bytes) - (Header Bytes) = Length of data, where Header Bytes is always 11.

RSA Key Length (bits)Length (bits)Length (bytes)
1024 936 117
2048 1960 245
3072 2984 373
4096 4008 501

When using OAEP, the following formula and table can be referenced. (RSA Key Bytes) - (2 * Hash Length Bytes) - 2 = Length of data. The table below assumes SHA-256 for the hash, so Hash Length Bytes is 32.

RSA Key Length (bits)Length (bits)Length (bytes)
1024 496 62
2048 1520 190
3072 2544 318
4096 3568 446

Encrypt Method (RSA Module)

Encrypts the input data using the recipient's public key.

Syntax

public func encrypt() throws -> Void

- (void)encrypt;

Remarks

This method encrypts the input data using the public key specified in RecipientKey. Alternatively, a certificate may be specified by setting RecipientCert.

Sign Method (RSA Module)

Creates a hash signature.

Syntax

public func sign() throws -> Void

- (void)sign;

Remarks

This method will create a hash signature.

Before calling this method specify the input file by setting InputFile or InputMessage.

A key is required to create the hash signature. You may create a new key by calling CreateKey, or specify an existing key pair in Key. Alternatively, a certificate may be specified by setting Certificate. When this method is called the class will compute the hash for the specified file and populate HashValue. It will then create the hash signature using the specified Key and populate HashSignature.

To create the hash signature without first computing the hash simply specify HashValue before calling this method.

The Progress event will fire with updates for the hash computation progress only. The hash signature creation process is quick and does not require progress updates.

Syntax

public func verifySignature() throws -> Bool

- (BOOL)verifySignature;

Remarks

This method will verify a hash signature.

Before calling this method specify the input file by setting InputFile or InputMessage.

A public key and the hash signature are required to perform the signature verification. Specify the public key in SignerKey. Alternatively, a certificate may be specified by setting SignerCert. Specify the hash signature in HashSignature.

When this method is called the class will compute the hash for the specified file and populate HashValue. It will verify the signature using the specified SignerKey and HashSignature.

To verify the hash signature without first computing the hash simply specify HashValue before calling this method.

The Progress event will fire with updates for the hash computation progress only. The hash signature verification process is quick and does not require progress updates.

    subject
    String
    Default Value: ""

    The subject of the certificate used for client authentication.

    This property must be set after all other certificate properties are set. When this property is set, a search is performed in the current certificate store to locate a certificate with a matching subject.

    If a matching certificate is found, the property is set to the full subject of the matching certificate.

    If an exact match is not found, the store is searched for subjects containing the value of the property.

    If a match is still not found, the property is set to an empty string, and no certificate is selected.

    The special value "*" picks a random certificate in the certificate store.

    The certificate subject is a comma-separated list of distinguished name fields and values. For instance, "CN=www.server.com, OU=test, C=US, E=support@nsoftware.com". Common fields and their meanings are as follows:

    FieldMeaning
    CNCommon Name. This is commonly a hostname like www.server.com.

    Constructors

    public init()

    Creates a instance whose properties can be set. This is useful for use with when generating new certificates. 

    public init(encoded: )

    Parses Encoded as an X.509 public key. 

    public init(storeType: , store: , storePassword: , subject: )

    StoreType identifies the type of certificate store to use. See for descriptions of the different certificate stores. Store is a file containing the certificate store. StorePassword is the password used to protect the store.

    After the store has been successfully opened, the component will attempt to find the certificate identified by Subject . This can be either a complete or a substring match of the X.509 certificate's subject Distinguished Name (DN). The Subject parameter can also take an MD5, SHA-1, or SHA-256 thumbprint of the certificate to load in a "Thumbprint=value" format. 

    public init(storeType: , store: , storePassword: , subject: )

    StoreType identifies the type of certificate store to use. See for descriptions of the different certificate stores. Store is a byte array containing the certificate data. StorePassword is the password used to protect the store.

    After the store has been successfully opened, the component will attempt to find the certificate identified by Subject . This can be either a complete or a substring match of the X.509 certificate's subject Distinguished Name (DN). The Subject parameter can also take an MD5, SHA-1, or SHA-256 thumbprint of the certificate to load in a "Thumbprint=value" format.

    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:

    • KeyModulus
    • KeyExponent

    The class also includes the KeyPublicKey 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 KeyPublicKey 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:

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

    The following fields are available:
  • D
  • DP
  • DQ
  • Exponent
  • InverseQ
  • Modulus
  • P
  • PrivateKey
  • PublicKey
  • Q

    Constructors

    public init()

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

    public init(modulus: , exponent: )

    The public key constructor assigns an existing public key. 

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

    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.

    Config Settings (RSA Module)

    The class accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.

    RSA Config Settings

    KeyFormat:   How the public and private key are formatted.

    This setting controls the format of KeyPublicKey and KeyPrivateKey. By default these properties hold PEM formatted public and private key data. When set to 1 (XML) the keys are stored in a XML format. This only affects the values returned by the class; the actual keys remain the same regardless of this setting. Possible values are:

    • 0 (PEM - PKCS#1)
    • 1 (XML)
    • 2 (PEM - PKCS#8 - default)
    The default value is 2 (PEM - PKCS#8).
    KeySize:   The size, in bits, of the secret key.

    This specifies the size, in bits, of the secret key. The minimum key size for RSA is 384. The maximum key size is 4096. Note that large values such as 4096 will impact performance. The default value is 1024.

    OAEPMGF1HashAlgorithm:   The MGF1 hash algorithm used with OAEP.

    This configuration setting specifies the MGF1 hash algorithm used when UseOAEP is set to True. The default value is SHA256. Possible values are as follows:

    • "SHA1"
    • "SHA224"
    • "SHA256" (default)
    • "SHA384"
    • "SHA512"
    • "RIPEMD160"
    • "MD2"
    • "MD5"
    • "MD5SHA1"

    Note: This setting is not applicable when UseFIPSCompliantAPI is set to or when the private key of the signing certificate is not exportable since the underlying system implementation does not support separate OAEPRSAHashAlgorithm and OAEPMGF1HashAlgorithm values. In this case the OAEPRSAHashAlgorithm is also used for MGF1.

    OAEPParams:   The hex encoded OAEP parameters.

    This configuration setting optionally specifies Optimal Asymmetric Encryption Padding (OAEP) parameters to be used when UseOAEP is set to True. The specified value should be hex encoded.

    OAEPRSAHashAlgorithm:   The RSA hash algorithm used with OAEP.

    This configuration setting specifies that RSA hash algorithm used when UseOAEP is set to True. The default value is SHA256. Possible values are as follows:

    • "SHA1"
    • "SHA224"
    • "SHA256" (default)
    • "SHA384"
    • "SHA512"
    • "RIPEMD160"
    • "MD2"
    • "MD5"
    • "MD5SHA1"

    Base Config Settings

    BuildInfo:   Information about the product's build.

    When queried, this setting will return a string containing information about the product's build.

    CodePage:   The system code page used for Unicode to Multibyte translations.

    The default code page is Unicode UTF-8 (65001).
