The DSA (Digital Signature Algorithm) module enables users to generate DSA hash signatures.

Syntax

IPWorksEncrypt.Dsa

Remarks

The DSA (Digital Signature Algorithm) class enables users to generate DSA hash signatures.

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

Signing

To sign data first set Key or Certificate. Select the input file by setting InputFile or InputMessage. Next call Sign. The Sign method will automatically compute the hash, and then sign the hash with the specified key.

Send the public key (see CreateKey for details), file, and HashSignature to the recipient.

To sign a hash without recomputing the hash simply set HashValue to the pre-computed hash value before calling Sign.

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.

To verify a hash signature without recomputing the hash simply set HashValue to the pre-computed hash value before calling VerifySignature.

Hash Notes

The class will determine whether or not to recompute the hash based on the properties that are set. If a file is specified by InputFile or InputMessage the hash will be recomputed when calling Sign or VerifySignature. If the HashValue property is set the class will only sign the hash or verify the hash signature. Setting InputFile or InputMessage clears the HashValue property. Setting the HashValue property clears the input file selection.

DSA Key Notes

A DSA key is made up of a number of individual parameters. When calling CreateKey the Key* properties are populated with a new private and public key.

After calling Sign the public key must be sent to the recipient along with HashSignature so they may perform signature verification. Likewise you must obtain the public key along with HashSignature in order to perform signature verification.

The public key consists of the following parameters:

  • KeyP
  • KeyQ
  • KeyG
  • KeyY

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 signature creation and 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 consists of the following parameters:

  • KeyP
  • KeyQ
  • KeyG
  • KeyY
  • KeyX
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..

- (NSData*)certEncodedB;
- (void)setCertEncodedB :(NSData*)newCertEncoded;

Default Value

""

Remarks

This is the certificate (PEM/base64 encoded). This property is used to assign a specific certificate. The CertStore and CertSubject properties also may be used to specify a certificate.

When CertEncoded is set, a search is initiated in the current CertStore for the private key of the certificate. If the key is found, CertSubject is updated to reflect the full subject of the selected certificate; otherwise, CertSubject is set to an empty string.

If an error occurs when setting this property an error will not be thrown. This property has a related method which will throw an error:

public func setCertEncodedB(certEncoded: Data) throws
public func setCertEncoded(certEncoded: String) throws

CertStore Property (DSA Module)

This is the name of the certificate store for the client certificate.

Syntax

public var certStore: String {

Default Value

"MY"

Remarks

This is the name of the certificate store for the client certificate.

The CertStoreType property denotes the type of the certificate store specified by CertStore. If the store is password protected, specify the password in CertStorePassword.

CertStore is used in conjunction with the CertSubject property to specify client certificates. If CertStore has a value, and CertSubject or CertEncoded is set, a search for a certificate is initiated. Please see the CertSubject property for details.

Designations of certificate stores are platform-dependent.

The following are designations of the most common User and Machine certificate stores in Windows:

MYA certificate store holding personal certificates with their associated private keys.
CACertifying authority certificates.
ROOTRoot certificates.

When the certificate store type is PFXFile, this property must be set to the name of the file. When the type is PFXBlob, the property must be set to the binary contents of a PFX file (i.e. PKCS12 certificate store).

Default Value

0

Remarks

This is the type of certificate store for this certificate.

The class supports both public and private keys in a variety of formats. When the cstAuto value is used the class will automatically determine the type. This property can take one of the following values:

0 (cstUser - default)For Windows, this specifies that the certificate store is a certificate store owned by the current user. Note: this store type is not available in Java.
1 (cstMachine)For Windows, this specifies that the certificate store is a machine store. Note: this store type is not available in Java.
2 (cstPFXFile)The certificate store is the name of a PFX (PKCS12) file containing certificates.

Remarks

This is the subject of the certificate used for client authentication.

This property must be set after all other certificate properites are set. When this property is set, a search is performed in the current certificate store certificate with 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 displayed below.

19 (cstJWKBlob)The certificate store is a string that contains a JWK (JSON Web Key).
20 (cstSecurityKey)The certificate is present on a physical security key accessible via a PKCS11 interface.

To use a security key the necessary data must first be collected using the CertMgr class. The ListStoreCertificates method may be called after setting CertStoreType to cstSecurityKey, CertStorePassword to the PIN, and CertStore to the full path of the PKCS11 dll. The certificate information returned in the CertList event's CertEncoded parameter may be saved for later use.

When using a certificate, pass the previously saved security key information as the SignerCertStore and set SignerCertStorePassword to the PIN.

Code Example: SSH Authentication with Security Key certmgr.CertStoreType = CertStoreTypes.cstSecurityKey; certmgr.OnCertList += (s, e) => { secKeyBlob = e.CertEncoded; }; certmgr.CertStore = @"C:\Program Files\OpenSC Project\OpenSC\pkcs11\opensc-pkcs11.dll"; certmgr.CertStorePassword = "123456"; //PIN certmgr.ListStoreCertificates(); sftp.SSHCert = new Certificate(CertStoreTypes.cstSecurityKey, secKeyBlob, "123456", "*"); sftp.SSHUser = "test"; sftp.SSHLogon("myhost", 22);

21 (cstBCFKSFile)The certificate store is the name of a file that contains a BCFKS (Bouncy Castle FIPS Key Store). Note: this store type is only available in Java and .NET.

False

Remarks

This property specifies whether HashValue and HashSignature are hex encoded.

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.

Config Method (DSA 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 (DSA Module)

Creates a new key.

Syntax

public func createKey() throws -> Void
- (void)createKey;

Remarks

This method creates a new public and private key.

DSA Key Notes

A DSA key is made up of a number of individual parameters. When calling CreateKey the Key* properties are populated with a new private and public key.

After calling Sign the public key must be sent to the recipient along with HashSignature so they may perform signature verification. Likewise you must obtain the public key along with HashSignature in order to perform signature verification.

The public key consists of the following parameters:

  • KeyP
  • KeyQ
  • KeyG
  • KeyY

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 signature creation and 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 consists of the following parameters:

  • KeyP
  • KeyQ
  • KeyG
  • KeyY
  • KeyX
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.

Reset Method (DSA Module)

Resets the component.

Syntax

public func reset() throws -> Void
- (void)reset;

Remarks

When called, the class will reset all of its properties to their default values.

Sign Method (DSA 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.

VerifySignature Method (DSA Module)

Verifies the signature for the specified data.

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.

Error Event (DSA Module)

Information about errors during data delivery.

Syntax

func onError(errorCode: Int32, description: String)
- (void)onError:(int)errorCode :(NSString*)description;

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the class .

ErrorCode contains an error code and Description contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

Progress Event (DSA Module)

Fired as progress is made.

Syntax

func onProgress(bytesProcessed: Int64, percentProcessed: Int32)
- (void)onProgress:(long long)bytesProcessed :(int)percentProcessed;

Remarks

This event is fired automatically as data is processed by the class.

The PercentProcessed parameter indicates the current status of the operation.

The BytesProcessed parameter holds the total number of bytes processed so far.

DSAKey Type

Contains the parameters for the DSA algorithm.

Remarks

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

DSA Key Notes

A DSA key is made up of a number of individual parameters. When calling CreateKey the Key* properties are populated with a new private and public key.

public init(p: , q: , g: , y: , x: )

The private key constructor assigns an existing private key.

Config Settings (DSA 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.

DSA Config Settings

HashSignatureFormat:   The format of the HashSignature.

This setting specifies the format of HashSignature when calling Sign. The way the HashSignature parameters are represented can be changed to be interoperable with other implementations. Possible values are:

0 (Concatenated - default) Compatible with Windows/.NET
1 (ASN) Compatible with OpenSSL/Mac/iOS

The default value is 0 (Concatenated). This setting is only applicable when calling Sign. When calling VerifySignature the format is automatically determined by the class.

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 DSA is 512. The maximum key size is 4096. Note that large values such as 4096 will impact performance. The default value is 1024.

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).
