# DSA Component The DSA (Digital Signature Algorithm) class enables users to generate DSA hash signatures. ## Syntax ```text ipworksencrypt.DSA ``` ## Remarks The DSA (Digital Signature Algorithm) struct 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 Key. To create a new key call [CreateKey](#createkey-method-dsa-component). Alternatively an existing certificate may be specified by setting Certificate **Signing** To sign data first set Key or Certificate. Select the input file by setting [InputFile](#inputfile-property-dsa-component) or [InputMessage](#inputmessage-property-dsa-component). Next call [Sign](#sign-method-dsa-component). The [Sign](#sign-method-dsa-component) method will automatically compute the hash, and then sign the hash with the specified key. Send the public key (see [CreateKey](#createkey-method-dsa-component) for details), file, and [HashSignature](#hashsignature-property-dsa-component) to the recipient. To sign a hash without recomputing the hash simply set [HashValue](#hashvalue-property-dsa-component) to the pre-computed hash value before calling [Sign](#sign-method-dsa-component). **Signature Verification** To verify a signature specify the input data using [InputFile](#inputfile-property-dsa-component) or [InputMessage](#inputmessage-property-dsa-component). Set SignerKey or SignerCert. Next set [HashSignature](#hashsignature-property-dsa-component) and call [VerifySignature](#verifysignature-method-dsa-component). The [VerifySignature](#verifysignature-method-dsa-component) method will return True if the signature was successfully verified. To verify a hash signature without recomputing the hash simply set [HashValue](#hashvalue-property-dsa-component) to the pre-computed hash value before calling [VerifySignature](#verifysignature-method-dsa-component). **Hash Notes** The struct will determine whether or not to recompute the hash based on the properties that are set. If a file is specified by [InputFile](#inputfile-property-dsa-component) or [InputMessage](#inputmessage-property-dsa-component), the hash will be recomputed when calling [Sign](#sign-method-dsa-component) or [VerifySignature](#verifysignature-method-dsa-component). If the [HashValue](#hashvalue-property-dsa-component) property is set, the struct will only sign the hash or verify the hash signature. Setting [InputFile](#inputfile-property-dsa-component) or [InputMessage](#inputmessage-property-dsa-component) clears the [HashValue](#hashvalue-property-dsa-component) property. Setting the [HashValue](#hashvalue-property-dsa-component) property clears the input file selection. **DSA Key Notes** A DSA key is made up of a number of individual parameters. When calling [CreateKey](#createkey-method-dsa-component) the key property is populated with a new private and public key. After calling [Sign](#sign-method-dsa-component) the public key must be sent to the recipient along with [HashSignature](#hashsignature-property-dsa-component) so they may perform signature verification. Likewise you must obtain the public key along with [HashSignature](#hashsignature-property-dsa-component) in order to perform signature verification. The public key consists of the following parameters: - [KeyP](#keyp-property-dsa-component) - [KeyQ](#keyq-property-dsa-component) - [KeyG](#keyg-property-dsa-component) - [KeyY](#keyy-property-dsa-component) The struct also includes the [KeyPublicKey](#keypublickey-property-dsa-component) 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](#keypublickey-property-dsa-component) in which case the individual parameters must be sent. The private key consists of the following parameters: - [KeyP](#keyp-property-dsa-component) - [KeyQ](#keyq-property-dsa-component) - [KeyG](#keyg-property-dsa-component) - [KeyY](#keyy-property-dsa-component) - [KeyX](#keyx-property-dsa-component) The struct also include the [KeyPrivateKey](#keyprivatekey-property-dsa-component) property which holds the PEM formatted private key for ease of use. This is helpful for storing the private key more easily.. ## Property List *The following is the full list of the properties of the component with short descriptions.

The value of [SignerCertUsageFlags](#signercertusageflags-property-dsa-component) is a combination of the following flags: | | | | --- | --- | | 0x80 | Digital Signature | | 0x40 | Non-Repudiation | | 0x20 | Key Encipherment | | 0x10 | Data Encipherment | | 0x08 | Key Agreement | | 0x04 | Certificate Signing | | 0x02 | CRL Signing | | 0x01 | Encipher Only | Please see the [SignerCertUsage](#signercertusage-property-dsa-component) property for a text representation of [SignerCertUsageFlags](#signercertusageflags-property-dsa-component). This functionality currently is not available when the provider is OpenSSL. This property is read-only. ## Data Type **int32** # SignerCertVersion Property ([DSA](#dsa-component) Component) The certificate's version number. ## Syntax *Go Syntax* ```text func (obj *DSA) SignerCertVersion() (string, error) ``` ## Default Value "" ## Remarks The certificate's version number. The possible values are the strings "V1", "V2", and "V3". This property is read-only. ## Data Type **string** # SignerCertSubject Property ([DSA](#dsa-component) Component) The subject of the certificate used for client authentication. ## Syntax *Go Syntax* ```text func (obj *DSA) SignerCertSubject() (string, error)func (obj *DSA) SetSignerCertSubject(value string) error ``` ## Default Value "" ## Remarks 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=example@email.com". Common fields and their meanings are as follows: | Field | Meaning | | --- | --- | | CN | Common Name. This is commonly a hostname like www.server.com. | | O | Organization | | OU | Organizational Unit | | L | Locality | | S | State | | C | Country | | E | Email Address | If a field value contains a comma, it must be quoted. ## Data Type **string** # SignerCertEncoded Property ([DSA](#dsa-component) Component) The certificate (PEM/Base64 encoded). ## Syntax *Go Syntax* ```text func (obj *DSA) SignerCertEncoded() ([]byte, error)func (obj *DSA) SetSignerCertEncoded(value []byte) error ``` ## Default Value "" ## Remarks The certificate (PEM/Base64 encoded). This property is used to assign a specific certificate. The [SignerCertStore](#signercertstore-property-dsa-component) and [SignerCertSubject](#signercertsubject-property-dsa-component) properties also may be used to specify a certificate. When [SignerCertEncoded](#signercertencoded-property-dsa-component) is set, a search is initiated in the current [SignerCertStore](#signercertstore-property-dsa-component) for the private key of the certificate. If the key is found, [SignerCertSubject](#signercertsubject-property-dsa-component) is updated to reflect the full subject of the selected certificate; otherwise, [SignerCertSubject](#signercertsubject-property-dsa-component) is set to an empty string. ## Data Type **[]byte** # SignerKeyG Property ([DSA](#dsa-component) Component) Represents the G parameter for the DSA algorithm. ## Syntax *Go Syntax* ```text func (obj *DSA) SignerKeyG() ([]byte, error)func (obj *DSA) SetSignerKeyG(value []byte) error ``` ## Default Value "" ## Remarks Represents the G parameter for the DSA algorithm. ## Data Type **[]byte** # SignerKeyP Property ([DSA](#dsa-component) Component) Represents the P parameter for the DSA algorithm. ## Syntax *Go Syntax* ```text func (obj *DSA) SignerKeyP() ([]byte, error)func (obj *DSA) SetSignerKeyP(value []byte) error ``` ## Default Value "" ## Remarks Represents the P parameter for the DSA algorithm. ## Data Type **[]byte** # SignerKeyPublicKey Property ([DSA](#dsa-component) Component) This property is a PEM formatted public key. ## Syntax *Go Syntax* ```text func (obj *DSA) SignerKeyPublicKey() (string, error)func (obj *DSA) SetSignerKeyPublicKey(value string) error ``` ## Default Value "" ## Remarks 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. ## Data Type **string** # SignerKeyQ Property ([DSA](#dsa-component) Component) Represents the Q parameter for the DSA algorithm. ## Syntax *Go Syntax* ```text func (obj *DSA) SignerKeyQ() ([]byte, error)func (obj *DSA) SetSignerKeyQ(value []byte) error ``` ## Default Value "" ## Remarks Represents the Q parameter for the DSA algorithm. ## Data Type **[]byte** # SignerKeyY Property ([DSA](#dsa-component) Component) Represents the Y parameter for the DSA algorithm. ## Syntax *Go Syntax* ```text func (obj *DSA) SignerKeyY() ([]byte, error)func (obj *DSA) SetSignerKeyY(value []byte) error ``` ## Default Value "" ## Remarks Represents the Y parameter for the DSA algorithm. ## Data Type **[]byte** # UseHex Property ([DSA](#dsa-component) Component) Whether HashValue and HashSignature are hex encoded. ## Syntax *Go Syntax* ```text func (obj *DSA) UseHex() (bool, error)func (obj *DSA) SetUseHex(value bool) error ``` ## Default Value false ## Remarks This property specifies whether [HashValue](#hashvalue-property-dsa-component) and [HashSignature](#hashsignature-property-dsa-component) are hex encoded. If set to True, when [Sign](#sign-method-dsa-component) is called the struct will compute the hash for the specified file and populate [HashValue](#hashvalue-property-dsa-component) with the hex encoded hash value. It will then create the hash signature and populate [HashSignature](#hashsignature-property-dsa-component) with the hex encoded hash signature value. If [HashValue](#hashvalue-property-dsa-component) is specified directly, it must be a hex encoded value. If set to True, when [VerifySignature](#verifysignature-method-dsa-component) is called the struct will compute the hash value for the specified file and populate [HashValue](#hashvalue-property-dsa-component) with the hex encoded hash value. It will then hex decode [HashSignature](#hashsignature-property-dsa-component) and verify the signature. [HashSignature](#hashsignature-property-dsa-component) must hold a hex encoded value. If [HashValue](#hashvalue-property-dsa-component) is specified directly, it must be a hex encoded value. ## Data Type **bool** # Config Method ([DSA](#dsa-component) Component) Sets or retrieves a configuration setting. ## Syntax *Go Syntax* ```text func (obj *DSA) Config(ConfigurationString string) (string, error) ``` ## Remarks Config is a generic method available in every struct. It is used to set and retrieve [configuration settings](#config-settings-dsa-component) for the struct. These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the struct, 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](#config-settings-dsa-component), you must call *Config("PROPERTY")*. The value will be returned as a string. # CreateKey Method ([DSA](#dsa-component) Component) Creates a new key. ## Syntax *Go Syntax* ```text func (obj *DSA) CreateKey() error ``` ## 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 property is populated with a new private and public key. After calling [Sign](#sign-method-dsa-component) the public key must be sent to the recipient along with [HashSignature](#hashsignature-property-dsa-component) so they may perform signature verification. Likewise you must obtain the public key along with [HashSignature](#hashsignature-property-dsa-component) in order to perform signature verification. The public key consists of the following parameters: - [KeyP](#keyp-property-dsa-component) - [KeyQ](#keyq-property-dsa-component) - [KeyG](#keyg-property-dsa-component) - [KeyY](#keyy-property-dsa-component) The struct also includes the [KeyPublicKey](#keypublickey-property-dsa-component) 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](#keypublickey-property-dsa-component) in which case the individual parameters must be sent. The private key consists of the following parameters: - [KeyP](#keyp-property-dsa-component) - [KeyQ](#keyq-property-dsa-component) - [KeyG](#keyg-property-dsa-component) - [KeyY](#keyy-property-dsa-component) - [KeyX](#keyx-property-dsa-component) The struct also include the [KeyPrivateKey](#keyprivatekey-property-dsa-component) 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](#dsa-component) Component) Resets the class. ## Syntax *Go Syntax* ```text func (obj *DSA) Reset() error ``` ## Remarks When called, the struct will reset all of its properties to their default values. # Sign Method ([DSA](#dsa-component) Component) Creates a hash signature. ## Syntax *Go Syntax* ```text func (obj *DSA) Sign() error ``` ## Remarks This method will create a hash signature. Before calling this method specify the input file by setting [InputFile](#inputfile-property-dsa-component) or [InputMessage](#inputmessage-property-dsa-component). A key is required to create the hash signature. You may create a new key by calling [CreateKey](#createkey-method-dsa-component), or specify an existing key pair in Key. Alternatively, a certificate may be specified by setting Certificate. When this method is called the struct will compute the hash for the specified file and populate [HashValue](#hashvalue-property-dsa-component). It will then create the hash signature using the specified Key and populate [HashSignature](#hashsignature-property-dsa-component). To create the hash signature without first computing the hash simply specify [HashValue](#hashvalue-property-dsa-component) before calling this method. The [Progress](#progress-event-dsa-component) 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](#dsa-component) Component) Verifies the signature for the specified data. ## Syntax *Go Syntax* ```text func (obj *DSA) VerifySignature() (bool, error) ``` ## Remarks This method will verify a hash signature. Before calling this method specify the input file by setting [InputFile](#inputfile-property-dsa-component) or [InputMessage](#inputmessage-property-dsa-component). 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](#hashsignature-property-dsa-component). When this method is called the struct will compute the hash for the specified file and populate [HashValue](#hashvalue-property-dsa-component). It will verify the signature using the specified SignerKey and [HashSignature](#hashsignature-property-dsa-component). To verify the hash signature without first computing the hash simply specify [HashValue](#hashvalue-property-dsa-component) before calling this method. The [Progress](#progress-event-dsa-component) 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](#dsa-component) Component) Fired when information is available about errors during data delivery. ## Syntax *Go Syntax* ```text // DSAErrorEventArgs carries the DSA Error event's parameters. type DSAErrorEventArgs struct {...} func (args *DSAErrorEventArgs) ErrorCode() int32 func (args *DSAErrorEventArgs) Description() string // DSAErrorEvent defines the signature of the DSA Error event's handler function. type DSAErrorEvent func(sender *DSA, args *DSAErrorEventArgs) func (obj *DSA) GetOnErrorHandler() DSAErrorEvent func (obj *DSA) SetOnErrorHandler(handlerFunc DSAErrorEvent) ``` ## Remarks The Error event is fired in case of exceptional conditions during message processing. Normally the struct fails with an error. The *ErrorCode* parameter contains an error code, and the *Description* parameter contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the [Error Codes](#trappable-errors-dsa-component) section. # Progress Event ([DSA](#dsa-component) Component) Fired as progress is made. ## Syntax *Go Syntax* ```text // DSAProgressEventArgs carries the DSA Progress event's parameters. type DSAProgressEventArgs struct {...} func (args *DSAProgressEventArgs) BytesProcessed() int64 func (args *DSAProgressEventArgs) PercentProcessed() int32 // DSAProgressEvent defines the signature of the DSA Progress event's handler function. type DSAProgressEvent func(sender *DSA, args *DSAProgressEventArgs) func (obj *DSA) GetOnProgressHandler() DSAProgressEvent func (obj *DSA) SetOnProgressHandler(handlerFunc DSAProgressEvent) ``` ## Remarks This event is fired automatically as data is processed by the struct. The *PercentProcessed* parameter indicates the current status of the operation. The *BytesProcessed* parameter holds the total number of bytes processed so far. # Config Settings ([DSA](#dsa-component) Component) The struct 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 struct, access to these *internal properties* is provided through the [Config](#config-method-dsa-component) method. ### DSA Config Settings **HashSignatureFormat**: The format of the HashSignature.This setting specifies the format of [HashSignature](#hashsignature-property-dsa-component) when calling [Sign](#sign-method-dsa-component). The way the [HashSignature](#hashsignature-property-dsa-component) 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](#sign-method-dsa-component). When calling [VerifySignature](#verifysignature-method-dsa-component) the format is automatically determined by the struct. **KeyFormat**: How the public and private key are formatted.This setting controls the format of [KeyPublicKey](#keypublickey-property-dsa-component) and [KeyPrivateKey](#keyprivatekey-property-dsa-component). 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 struct; 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).

It will return the following information: - Product: The product the license is for. - Product Key: The key the license was generated from. - License Source: Where the license was found (e.g., RuntimeLicense, License File). - License Type: The type of license installed (e.g., Royalty Free, Single Server). - Last Valid Build: The last valid build number for which the license will work. **MaskSensitiveData**: Whether sensitive data is masked in log messages.In certain circumstances it may be beneficial to mask sensitive data, like passwords, in log messages. Set this to *true* to mask sensitive data. The default is *true*. **UseInternalSecurityAPI**: Whether or not to use the system security libraries or an internal implementation. When set to *false*, the struct will use the system security libraries by default to perform cryptographic functions where applicable. Setting this configuration setting to *true* tells the struct to use the internal implementation instead of using the system security libraries. On Windows, this setting is set to *false* by default. On Linux/macOS, this setting is set to *true* by default. To use the system security libraries for Linux, OpenSSL support must be enabled. For more information on how to enable OpenSSL, please refer to the [OpenSSL Notes](platforms.md) section. # Trappable Errors ([DSA](#dsa-component) Component) ### DSA Errors | | | | --- | --- | | 102 | No Key specified. | | 104 | Cannot read or write file. | | 105 | Key parameters incorrect. | | 106 | Cannot create hash. | | 113 | Input data or HashValue must be specified. | | 121 | Invalid certificate. | | 124 | HashSignature must be specified. | | 304 | Cannot write file. | | 305 | Cannot read file. | | 1201 | Specified DSA parameters are invalid. | | 1202 | Missing hash value. | | 1203 | Public key must be specified. | | 1204 | Key must be specified. | | 1205 | HashSignature must be specified. | | 1206 | Invalid key size. |
