# JWS Class Create, Sign and Verify JSON Web Signatures (JWS). ## Syntax **ipworksencrypt.jws()** ## Remarks The JWS class supports signing and verifying JSON Web Signatures (JWS). Specify any payload via input properties and use [Sign](#jwssign-method) to create a JWS message using a variety of algorithms including HMAC, RSA, and ECDSA. Use [Verify](#jwsverify-method) to verify the signature of any received JWS message. The following algorithms are supported: - HS256 - HS384 - HS512 - RS256 - RS384 - RS512 - PS256 - PS384 - PS512 - ES256 - ES384 - ES512 - None See [Algorithm](#jwsalgorithm-property) for more details about supported algorithms. ## Signing The [Sign](#jwssign-method) method may be used to sign a payload with a variety of algorithms. Before calling the [Sign](#jwssign-method) method set [Algorithm](#jwsalgorithm-property) to the algorithm which will be used to sign the message. The result of signing is a compact serialized JWS string. For instance: *eyJhbGciOiJIUzI1NiJ9.dGVzdA.o_JihJlCwvBO1AgY_Ao3_VBivdFmj3ufv3ZWAqYF4Ow* The class is agnostic of the payload that is signed. Any value may be signed. [KeyId](#jwskeyid-property) may be set to include an identifier to help the receiving party identify the key used to sign the message. The following properties are applicable when calling this method: - [Algorithm](#jwsalgorithm-property) (required) - [Certificate](#jwscertificate-property) (conditional - required for ECDSA and RSA) - [Key](#jwskey-property) (conditional - required for HMAC) - [HeaderParams](#jwsheaderparams-property) - [KeyId](#jwskeyid-property) - [Overwrite](#jwsoverwrite-property) **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: - [InputFile](#jwsinputfile-property) - [InputMessage](#jwsinputmessage-property) When a valid source is found, the search stops. The order in which the output properties are checked is as follows: - [OutputFile](#jwsoutputfile-property) - [OutputMessage](#jwsoutputmessage-property): The output data is written to this property if no other destination is specified. **Notes for HMAC Algorithms (HS256, HS384, HS512)** When [Algorithm](#jwsalgorithm-property) is set to a HMAC algorithm [Key](#jwskey-property) must be set to a key of appropriate length for the algorithm. The [Key](#jwskey-property) should be the same number of bits as the algorithm being used. For instance a 256 bit key would be used for HS256. The example code below uses the [EzRand](EzRand.md#EzRand) class to generate a key, but the key may be created using any means. The key must be known by both parties in order for signing and verification to take place. ```csharp //Generate a 256 bit (32 byte) key Ezrand ezrand = new Ezrand(); ezrand.RandBytesLength = 32; ezrand.GetNextBytes(); byte[] key = ezrand.RandBytesB; //Sign the payload using HS256 Jws jws = new Jws(); jws.Algorithm = JwsAlgorithms.jwsHS256; jws.InputMessage = "test data"; jws.KeyB = key; jws.Sign(); string signedData = jws.OutputMessage; ``` To use an existing HMAC key provide the bytes to the [Key](#jwskey-property) property. For instance: ```csharp //HMAC SHA-256 Key byte[] key = new byte[] { 170, 171, 221, 209, 7, 181, 48, 178, 48, 118, 242, 132, 36, 218, 74, 140, 216, 165, 161, 70, 11, 42, 246, 205, 235, 231, 19, 48, 87, 141, 122, 10 }; //Sign the payload using HS256 Jws jws = new Jws(); jws.Algorithm = JwsAlgorithms.jwsHS256; jws.InputMessage = "test data"; jws.KeyB = key; jws.Sign(); string signedData = jws.OutputMessage; ``` **Notes for RSA Algorithms (RS256, RS384, RS512, PS256, PS384, PS512)** The RSA based algorithms use asymmetric encryption. Signing is done with a private key and verification is done with a public key. The private key may be in PFX or PEM format. ```csharp Jws jws = new Jws(); jws.Algorithm = JwsAlgorithms.jwsRS256; jws.Certificate = new Certificate(CertStoreTypes.cstPFXFile, "..\\jwt.pfx", "test", "*"); jws.InputMessage = "test"; jws.Sign(); string signedMessage = jws.OutputMessage; ``` **Notes for ECDSA Algorithms (ES256, ES384, ES512)** ECDSA algorithms require a valid ECC private key to sign. The [ECC](ECC.md#ECC) class can be used to create or import an ECC key into the *Certificate* format accepted by the *JWS* class. ```csharp //Create an ECC key with SHA-256 Ecc ecc = new Ecc(); ecc.HashAlgorithm = EccHashAlgorithms.ehaSHA256; ecc.CreateKey(); string privKey = ecc.Key.PrivateKey; //Sign the payload using ES256 Jws jws = new Jws(); jws.Algorithm = JwsAlgorithms.jwsES256; jws.Certificate = new Certificate(CertStoreTypes.cstPEMKeyBlob, privKey, "", "*"); jws.InputMessage = "test"; jws.Sign(); string signedMessage = jws.OutputMessage; ``` To use an existing ECC Key populate the *Rx*, *Ry*, and *K* values of *Key* property in the [ECC](ECC.md#ECC) class first. For instance: ```csharp //Import an existing ECC private key Ecc ecc = new Ecc(); byte[] x_bytes = new byte[] { 171, 170, 196, 151, 94, 196, 231, 12, 128, 232, 17, 61, 45, 105, 41, 209, 192, 187, 112, 242, 110, 178, 95, 240, 36, 55, 83, 171, 190, 176, 78, 13 }; byte[] y_bytes = new byte[] { 197, 75, 134, 245, 245, 28, 199, 9, 7, 117, 1, 54, 49, 178, 135, 252, 62, 89, 35, 180, 117, 80, 231, 23, 110, 250, 28, 124, 219, 253, 224, 156 }; byte[] k_bytes = new byte[] { 81, 65, 201, 24, 235, 249, 162, 148, 169, 150, 109, 181, 61, 238, 145, 122, 31, 30, 151, 94, 239, 90, 222, 217, 63, 103, 54, 2, 176, 232, 248, 168 }; ecc.Key.RxB = x_bytes; ecc.Key.RyB = y_bytes; ecc.Key.KB = k_bytes; string privKey = ecc.Key.PrivateKey; //Sign the payload using ES256 Jws jws = new Jws(); jws.Algorithm = JwsAlgorithms.jwsES256; jws.Certificate = new Certificate(CertStoreTypes.cstPEMKeyBlob, privKey, "", "*"); jws.InputMessage = "test"; jws.Sign(); string signedMessage = jws.OutputMessage; ``` **Notes for Unsecured (none)** To create a JWS token without any security set [Algorithm](#jwsalgorithm-property) to *jwsNone*. ```csharp Jws jws = new Jws(); jws.Algorithm = JwsAlgorithms.jwsNone; jws.InputMessage = "test"; jws.Sign(); string unsecuredMessage = jws.OutputMessage; ``` ## Signature Verification The [Verify](#jwsverify-method) method may be used to verify a received JWS message. Before calling the [Verify](#jwsverify-method) method set [InputMessage](#jwsinputmessage-property) or [InputFile](#jwsinputfile-property) to a valid compact serialized JWS string. For instance: *eyJhbGciOiJIUzI1NiJ9.dGVzdA.o_JihJlCwvBO1AgY_Ao3_VBivdFmj3ufv3ZWAqYF4Ow* [Key](#jwskey-property) or [Certificate](#jwscertificate-property) should be set to the HMAC key or public certificate respectively. If the correct [Key](#jwskey-property) or [Certificate](#jwscertificate-property) is not known ahead of time the *KeyId* parameter of the [SignerInfo](#jwssignerinfo-event) event may be used to identify the correct key. If this method returns without error verification was successful. If verification fails then this method . After calling this method the payload will be present in the [OutputMessage](#jwsoutputmessage-property) or file specified by [OutputFile](#jwsoutputfile-property) and the [HeaderParams](#jwsheaderparams-property) property will contain the headers. Headers of the parsed message are also available through the [HeaderParam](#jwsheaderparam-event) event. The following properties are applicable when calling this method: - [Key](#jwskey-property) (conditional - required for HMAC) - [Certificate](#jwscertificate-property) (conditional - required for ECDSA and RSA) - [Algorithm](#jwsalgorithm-property) (only if [StrictValidation](#StrictValidation) is True) - [Overwrite](#jwsoverwrite-property) - [StrictValidation](#StrictValidation) **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: - [InputFile](#jwsinputfile-property) - [InputMessage](#jwsinputmessage-property) When a valid source is found, the search stops. The order in which the output properties are checked is as follows: - [OutputFile](#jwsoutputfile-property) - [OutputMessage](#jwsoutputmessage-property): The output data is written to this property if no other destination is specified. **Notes for HMAC Algorithms (HS256, HS384, HS512)** When verifying a message originally signed with a HMAC algorithm [Key](#jwskey-property) must be set to the same key used during signing. The key must be known by both parties in order for signing and verification to take place. ```csharp byte[] key = new byte[] { 170, 171, 221, 209, 7, 181, 48, 178, 48, 118, 242, 132, 36, 218, 74, 140, 216, 165, 161, 70, 11, 42, 246, 205, 235, 231, 19, 48, 87, 141, 122, 10 }; Jws jws = new Jws(); jws.KeyB = key; jws.InputMessage = signedData; jws.Verify(); string verifiedPayload = jws.OutputMessage; ``` **Notes for RSA Algorithms (RS256, RS384, RS512, PS256, PS384, PS512)** The RSA based algorithms use asymmetric encryption. Signing is done with a private key and verification is done with a public key. The public key is typically in PEM format. ```csharp Jws jws = new Jws(); jws.Certificate = new Certificate("..\\jwt.cer"); jws.InputMessage = signedData; jws.Verify(); string verifiedPayload = jws.OutputMessage; ``` **Notes for ECDSA Algorithms (ES256, ES384, ES512)** ECDSA algorithms require a valid ECC public key to verify the message. If the key was originally created with the [ECC](ECC.md#ECC) class the PEM encoded *PublicKey* may be used directly with the [Certificate](#jwscertificate-property) property. An example PEM encoded public certificate created by the [ECC](ECC.md#ECC) class: ```text -----BEGIN PUBLIC KEY----- MIIBMjCB7AYHKoZIzj0CATCB4AIBATAsBgcqhkjOPQEBAiEA/////wAAAAEAAAAAAAAAAAAA AAD///////////////8wRAQg/////wAAAAEAAAAAAAAAAAAAAAD///////////////wEIFrG NdiqOpPns+u9VXaYhrxlHQawzFOw9jvOPD4n0mBLBEEEaxfR8uEsQkf4vOblY6RA8ncDfYEt 6zOg9KE5RdiYwpZP40Li/hp/m47n60p8D54WK84zV2sxXs7LtkBoN79R9QIhAP////8AAAAA //////////+85vqtpxeehPO5ysL8YyVRAgEBA0EEIC5rbLp11Mnz6cBXLLriaDIov3rm8RAY x/OR0bOKiff0cQy+sLVaxjseqFk/+Xvl4ORSv5Z6HdHv5GyEpA0UoA== -----END PUBLIC KEY----- ``` ```csharp Jws jws = new Jws(); jws.Certificate = new Certificate(CertStoreTypes.cstPublicKeyFile, pubKey, "", "*"); jws.InputMessage = signedData; jws.Verify(); string verifiedPayload = jws.OutputMessage; ``` To use an ECC public key created by other means the [ECC](ECC.md#ECC) class may be used to import the key parameters. Populate the *Rx* and *Ry* of the [ECC](ECC.md#ECC) class first to obtain the PEM formatted public key. For instance: ```csharp //Import an existing ECC public key Ecc ecc = new Ecc(); byte[] x_bytes = new byte[] { 171, 170, 196, 151, 94, 196, 231, 12, 128, 232, 17, 61, 45, 105, 41, 209, 192, 187, 112, 242, 110, 178, 95, 240, 36, 55, 83, 171, 190, 176, 78, 13 }; byte[] y_bytes = new byte[] { 197, 75, 134, 245, 245, 28, 199, 9, 7, 117, 1, 54, 49, 178, 135, 252, 62, 89, 35, 180, 117, 80, 231, 23, 110, 250, 28, 124, 219, 253, 224, 156 }; ecc.Key.RxB = x_bytes; ecc.Key.RyB = y_bytes; string pubKey = ecc.Key.PublicKey; Jws jws = new Jws(); jws.Certificate = new Certificate(CertStoreTypes.cstPublicKeyFile, pubKey, "", "*"); jws.InputMessage = signedData; jws.Verify(); string verifiedPayload = jws.OutputMessage; ``` **Notes for Unsecured (none)** To parse a JWS token without any security call the [Sign](#jwssign-method) method without setting [Key](#jwskey-property) or [Certificate](#jwscertificate-property). ```csharp Jws jws = new Jws(); jws.InputMessage = signedData; jws.Verify(); string unsecuredPayload = jws.OutputMessage; ``` ## Other Functionality In addition to standard signing and verifying the class also supports a variety of other features including: - Adding custom header parameters with [AddHeaderParam](#jwsaddheaderparam-method) - Enforcing algorithm restrictions when verifying by setting [StrictValidation](#StrictValidation) - Inspect the JWS without verifying by calling [Parse](#jwsparse-method) ## Property List *The following is the full list of the properties of the class with short descriptions.

When signing with an HMAC algorithm [Key](#jwskey-property) must be specified. When an RSA or ECDSA algorithm is selected [Certificate](#jwscertificate-property) must be set before calling [Sign](#jwssign-method) and [Certificate](#jwscertificate-property) must be set before calling [Verify](#jwsverify-method). The following values are supported: | Algorithm | Description | Private Key Location | | --- | --- | --- | | 0 (jwsHS256 - default) | HMAC using SHA-256 | [Key](#jwskey-property) | | 1 (jwsHS384) | HMAC using SHA-384 | [Key](#jwskey-property) | | 2 (jwsHS512) | HMAC using SHA-512 | [Key](#jwskey-property) | | 3 (jwsRS256) | RSASSA-PKCS1-v1_5 using SHA-256 | [Certificate](#jwscertificate-property) | | 4 (jwsRS384) | RSASSA-PKCS1-v1_5 using SHA-384 | [Certificate](#jwscertificate-property) | | 5 (jwsRS512) | RSASSA-PKCS1-v1_5 using SHA-512 | [Certificate](#jwscertificate-property) | | 6 (jwsPS256) | RSASSA-PSS using SHA-256 and MGF1 with SHA-256 | [Certificate](#jwscertificate-property) | | 7 (jwsPS384) | RSASSA-PSS using SHA-384 and MGF1 with SHA-384 | [Certificate](#jwscertificate-property) | | 8 (jwsPS512) | RSASSA-PSS using SHA-512 and MGF1 with SHA-512 | [Certificate](#jwscertificate-property) | | 9 (jwsES256) | ECDSA using P-256 and SHA-256 | [Certificate](#jwscertificate-property) | | 10 (jwsES384) | ECDSA using P-384 and SHA-384 | [Certificate](#jwscertificate-property) | | 11 (jwsES512) | ECDSA using P-521 and SHA-512 | [Certificate](#jwscertificate-property) | | 12 (jwsES256K) | ECDSA using secp256k1 curve and SHA-256 | [Certificate](#jwscertificate-property) | | 99 (jwsNone) | None (unprotected) | Not Applicable | Note: This setting is also applicable when [StrictValidation](#StrictValidation) is enabled before calling [Verify](#jwsverify-method). # [JWS](#jws-class).Certificate Property The certificate used for signing or verification. ## Syntax ```text getCertificate(): Certificate; setCertificate(certificate: Certificate): void; ``` ## Default Value ## Remarks This property specifies a certificate used for signing or verification. When calling [Sign](#jwssign-method) and [Algorithm](#jwsalgorithm-property) is set to an RSA or ECDSA algorithm this property must be set to a certificate with private key. When calling [Verify](#jwsverify-method) and the algorithm used is RSA or ECDSA this property must be set to the public certificate of the signer. Please refer to the [Certificate](#certificate-type) type for a complete list of fields. # [JWS](#jws-class).HeaderParams Property The JOSE header parameters. ## Syntax ```text getHeaderParams(): HeaderParamList; ``` ## Default Value ## Remarks This property specifies the JOSE header parameters. This may be populated before calling [Sign](#jwssign-method) or Encrypt. This is populated with the parsed header values after calling [Verify](#jwsverify-method), Decrypt, or [Parse](#jwsparse-method). This property is not available at design time. Please refer to the [HeaderParam](#headerparam-type) type for a complete list of fields. # [JWS](#jws-class).InputFile Property The file to process. ## Syntax ```text getInputFile(): string; setInputFile(inputFile: string): void; ``` ## Default Value "" ## Remarks This property specifies the file to be processed. Set this property to the full or relative path to the file which will be processed. **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: - InputFile - [InputMessage](#jwsinputmessage-property) When a valid source is found, the search stops. The order in which the output properties are checked is as follows: - [OutputFile](#jwsoutputfile-property) - [OutputMessage](#jwsoutputmessage-property): The output data is written to this property if no other destination is specified. # [JWS](#jws-class).InputMessage Property The message to process. ## Syntax ```text getInputMessage(): Uint8Array; setInputMessage(inputMessage: Uint8Array): void; ``` ## Default Value "" ## Remarks This property specifies the message to be processed. **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: - [InputFile](#jwsinputfile-property) - InputMessage When a valid source is found, the search stops. The order in which the output properties are checked is as follows: - [OutputFile](#jwsoutputfile-property) - [OutputMessage](#jwsoutputmessage-property): The output data is written to this property if no other destination is specified. # [JWS](#jws-class).Key Property The secret key for the hash algorithm. ## Syntax ```text getKey(): Uint8Array; setKey(key: Uint8Array): void; ``` ## Default Value "" ## Remarks This property holds the secret key used when creating the hash. The key can be arbitrarily long. Note: This property is only applicable when [Algorithm](#jwsalgorithm-property) is set to an HMAC algorithm. It is recommended that the length of the key be equal to or larger than the hash size of the algorithm. Use of keys shorter than the hash size is discouraged. **Sizes (in bytes)** | | | | | | | | | | --- | --- | --- | --- | --- | --- | --- | --- | | | SHA1 | SHA224 | SHA256 | SHA384 | SHA512 | MD5 | RIPEMD160 | | Recommended Key Size | 20 | 28 | 32 | 48 | 64 | 16 | 20 | | Hash Size | 20 | 28 | 32 | 48 | 64 | 16 | 20 | | Block Size | 64 | 64 | 64 | 128 | 128 | 64 | 64 | **Key Length Details** As mentioned above it is recommended to use a key size equal to the hash size. Use of keys larger than the hash size does not typically significantly increase the function strength. Keys of any length are technically valid however see the below processing rules to understand how keys of varying lengths are treated: - If the key length is equal to the hash size (recommended) it is used without modification. - If the key length is less than the hash size it is used without modification. - If the key length is less than or equal to the block size it is used without modification. - If the key length is larger than the block size it is first hashed with the same algorithm. # [JWS](#jws-class).KeyId Property The Id of the key used to sign the message. ## Syntax ```text getKeyId(): string; setKeyId(keyId: string): void; ``` ## Default Value "" ## Remarks This property optionally specifies the Id of the key used to sign the message. Any string value may be supplied here to help the other party identify the key used to sign the message. This may be set before calling the [Sign](#jwssign-method) method. # [JWS](#jws-class).OutputFile Property The output file when encrypting or decrypting. ## Syntax ```text getOutputFile(): string; setOutputFile(outputFile: string): void; ``` ## Default Value "" ## Remarks This property specifies the file to which the output will be written when Encrypt or Decrypt is called. This may be set to an absolute or relative path. This property is only applicable to Encrypt and Decrypt. **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: - [InputFile](#jwsinputfile-property) - [InputMessage](#jwsinputmessage-property) When a valid source is found, the search stops. The order in which the output properties are checked is as follows: - OutputFile - [OutputMessage](#jwsoutputmessage-property): The output data is written to this property if no other destination is specified. # [JWS](#jws-class).OutputMessage Property The output message after processing. ## Syntax ```text getOutputMessage(): Uint8Array; ``` ## Default Value "" ## Remarks This property will be populated with the output from the operation if [OutputFile](#jwsoutputfile-property) is not set. **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: - [InputFile](#jwsinputfile-property) - [InputMessage](#jwsinputmessage-property) When a valid source is found, the search stops. The order in which the output properties are checked is as follows: - [OutputFile](#jwsoutputfile-property) - OutputMessage: The output data is written to this property if no other destination is specified. This property is read-only and not available at design time. # [JWS](#jws-class).Overwrite Property Indicates whether or not the class should overwrite files. ## Syntax ```text isOverwrite(): boolean; setOverwrite(overwrite: boolean): void; ``` ## Default Value FALSE ## Remarks This property indicates whether or not the class will overwrite [OutputFile](#jwsoutputfile-property). If Overwrite is False, an error will be thrown whenever [OutputFile](#jwsoutputfile-property) exists before an operation. The default value is False. # [JWS](#jws-class).addHeaderParam Method Adds additional header parameters. ## Syntax ```text async jws.addHeaderParam(name : string, value : string, dataType : number): Promise< void> ``` ## Remarks This method is used to add additional header parameters before calling [Sign](#jwssign-method). The *Name* and *Value* parameters define the name and value of the parameter respectively. The *DataType* parameter specifies the JSON data type of the value. Possible values for *DataType* are: - 0 (Object) - 1 (Array) - 2 (String) - 3 (Number) - 4 (Bool) - 5 (Null) To add additional parameters to the JOSE header use this method. For instance to create this header: ```text { "alg": "HS512", "crit": [ "exp" ], "exp": 12345687, "kid": "myKeyId", "type": "JWT" } ``` The following code can be used: ```csharp jws.Algorithm = JwsAlgorithms.jwsHS512; jws.KeyId = "myKeyId"; jws.KeyB = key; jws.AddHeaderParam("type", "JWT", 2); jws.AddHeaderParam("crit", "[\"exp\"]", 1); jws.AddHeaderParam("exp", "12345687", 3); jws.InputMessage = "test"; jws.Sign(); string signedData = jws.OutputMessage; ``` Note: when calling [Sign](#jwssign-method) the class will automatically add some headers based on properties that are set. **Parameters Automatically Set:** | Header Param | Property | | --- | --- | | alg | [Algorithm](#jwsalgorithm-property) | | kid | [KeyId](#jwskeyid-property) | # [JWS](#jws-class).config Method Sets or retrieves a configuration setting. ## Syntax ```text async jws.config(configurationString : string): Promise< string> ``` ## Remarks Config is a generic method available in every class. It is used to set and retrieve [configuration settings](#config-settings-class-ipworksencryptjws) 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](#config-settings-class-ipworksencryptjws), you must call *Config("PROPERTY")*. The value will be returned as a string. # [JWS](#jws-class).parse Method Parses the compact serialized JWS string. ## Syntax ```text async jws.parse(): Promise< void> ``` ## Remarks This method parses, but does not verify, the JWS string. Take care when using this method as no signature verification is performed. This method may be helpful in cases where information about the signature is contained within the payload, or for any other reason where the signature is not important. If verification is desired, use [Verify](#jwsverify-method) instead. It is not necessary to call this method before calling [Verify](#jwsverify-method). [Verify](#jwsverify-method) will both parse and verify the message. When calling this method the headers and payload are parsed. The [HeaderParam](#jwsheaderparam-event) and [SignerInfo](#jwssignerinfo-event) events will fire and the [HeaderParams](#jwsheaderparams-property) property will be populated. The payload will be written to the specified output location. **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: - [InputFile](#jwsinputfile-property) - [InputMessage](#jwsinputmessage-property) When a valid source is found, the search stops. The order in which the output properties are checked is as follows: - [OutputFile](#jwsoutputfile-property) - [OutputMessage](#jwsoutputmessage-property): The output data is written to this property if no other destination is specified. # [JWS](#jws-class).reset Method Resets the class. ## Syntax ```text async jws.reset(): Promise< void> ``` ## Remarks When called, the class will reset all of its properties to their default values. # [JWS](#jws-class).setInputStream Method Sets the stream from which the class will read data. ## Syntax ```text async jws.setInputStream(inputStream : ReadableStream): Promise< void> ``` ## Remarks This method may be used to set a stream from which data will be read. **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: - [InputFile](#jwsinputfile-property) - [InputMessage](#jwsinputmessage-property) When a valid source is found, the search stops. The order in which the output properties are checked is as follows: - [OutputFile](#jwsoutputfile-property) - [OutputMessage](#jwsoutputmessage-property): The output data is written to this property if no other destination is specified. # [JWS](#jws-class).setOutputStream Method Sets the stream to which the class will write data. ## Syntax ```text async jws.setOutputStream(outputStream : WriteableStream): Promise< void> ``` ## Remarks This method may be used to specify a stream to which data will be written. **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: - [InputFile](#jwsinputfile-property) - [InputMessage](#jwsinputmessage-property) When a valid source is found, the search stops. The order in which the output properties are checked is as follows: - [OutputFile](#jwsoutputfile-property) - [OutputMessage](#jwsoutputmessage-property): The output data is written to this property if no other destination is specified. # [JWS](#jws-class).sign Method Signs the payload with the specified algorithm. ## Syntax ```text async jws.sign(): Promise< void> ``` ## Remarks This method signs the input with the specified [Algorithm](#jwsalgorithm-property). Before calling the Sign method set [Algorithm](#jwsalgorithm-property) to the algorithm which will be used to sign the message. The result of signing is a compact serialized JWS string. For instance: *eyJhbGciOiJIUzI1NiJ9.dGVzdA.o_JihJlCwvBO1AgY_Ao3_VBivdFmj3ufv3ZWAqYF4Ow* The class is agnostic of the payload that is signed. Any value may be signed. [KeyId](#jwskeyid-property) may be set to include an identifier to help the receiving party identify the key used to sign the message. The following properties are applicable when calling this method: - [Algorithm](#jwsalgorithm-property) (required) - [Certificate](#jwscertificate-property) (conditional - required for ECDSA and RSA) - [Key](#jwskey-property) (conditional - required for HMAC) - [HeaderParams](#jwsheaderparams-property) - [KeyId](#jwskeyid-property) - [Overwrite](#jwsoverwrite-property) **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: - [InputFile](#jwsinputfile-property) - [InputMessage](#jwsinputmessage-property) When a valid source is found, the search stops. The order in which the output properties are checked is as follows: - [OutputFile](#jwsoutputfile-property) - [OutputMessage](#jwsoutputmessage-property): The output data is written to this property if no other destination is specified. **Notes for HMAC Algorithms (HS256, HS384, HS512)** When [Algorithm](#jwsalgorithm-property) is set to a HMAC algorithm [Key](#jwskey-property) must be set to a key of appropriate length for the algorithm. The [Key](#jwskey-property) should be the same number of bits as the algorithm being used. For instance a 256 bit key would be used for HS256. The example code below uses the [EzRand](EzRand.md#EzRand) class to generate a key, but the key may be created using any means. The key must be known by both parties in order for signing and verification to take place. ```csharp //Generate a 256 bit (32 byte) key Ezrand ezrand = new Ezrand(); ezrand.RandBytesLength = 32; ezrand.GetNextBytes(); byte[] key = ezrand.RandBytesB; //Sign the payload using HS256 Jws jws = new Jws(); jws.Algorithm = JwsAlgorithms.jwsHS256; jws.InputMessage = "test data"; jws.KeyB = key; jws.Sign(); string signedData = jws.OutputMessage; ``` To use an existing HMAC key provide the bytes to the [Key](#jwskey-property) property. For instance: ```csharp //HMAC SHA-256 Key byte[] key = new byte[] { 170, 171, 221, 209, 7, 181, 48, 178, 48, 118, 242, 132, 36, 218, 74, 140, 216, 165, 161, 70, 11, 42, 246, 205, 235, 231, 19, 48, 87, 141, 122, 10 }; //Sign the payload using HS256 Jws jws = new Jws(); jws.Algorithm = JwsAlgorithms.jwsHS256; jws.InputMessage = "test data"; jws.KeyB = key; jws.Sign(); string signedData = jws.OutputMessage; ``` **Notes for RSA Algorithms (RS256, RS384, RS512, PS256, PS384, PS512)** The RSA based algorithms use asymmetric encryption. Signing is done with a private key and verification is done with a public key. The private key may be in PFX or PEM format. ```csharp Jws jws = new Jws(); jws.Algorithm = JwsAlgorithms.jwsRS256; jws.Certificate = new Certificate(CertStoreTypes.cstPFXFile, "..\\jwt.pfx", "test", "*"); jws.InputMessage = "test"; jws.Sign(); string signedMessage = jws.OutputMessage; ``` **Notes for ECDSA Algorithms (ES256, ES384, ES512)** ECDSA algorithms require a valid ECC private key to sign. The [ECC](ECC.md#ECC) class can be used to create or import an ECC key into the *Certificate* format accepted by the *JWS* class. ```csharp //Create an ECC key with SHA-256 Ecc ecc = new Ecc(); ecc.HashAlgorithm = EccHashAlgorithms.ehaSHA256; ecc.CreateKey(); string privKey = ecc.Key.PrivateKey; //Sign the payload using ES256 Jws jws = new Jws(); jws.Algorithm = JwsAlgorithms.jwsES256; jws.Certificate = new Certificate(CertStoreTypes.cstPEMKeyBlob, privKey, "", "*"); jws.InputMessage = "test"; jws.Sign(); string signedMessage = jws.OutputMessage; ``` To use an existing ECC Key populate the *Rx*, *Ry*, and *K* values of *Key* property in the [ECC](ECC.md#ECC) class first. For instance: ```csharp //Import an existing ECC private key Ecc ecc = new Ecc(); byte[] x_bytes = new byte[] { 171, 170, 196, 151, 94, 196, 231, 12, 128, 232, 17, 61, 45, 105, 41, 209, 192, 187, 112, 242, 110, 178, 95, 240, 36, 55, 83, 171, 190, 176, 78, 13 }; byte[] y_bytes = new byte[] { 197, 75, 134, 245, 245, 28, 199, 9, 7, 117, 1, 54, 49, 178, 135, 252, 62, 89, 35, 180, 117, 80, 231, 23, 110, 250, 28, 124, 219, 253, 224, 156 }; byte[] k_bytes = new byte[] { 81, 65, 201, 24, 235, 249, 162, 148, 169, 150, 109, 181, 61, 238, 145, 122, 31, 30, 151, 94, 239, 90, 222, 217, 63, 103, 54, 2, 176, 232, 248, 168 }; ecc.Key.RxB = x_bytes; ecc.Key.RyB = y_bytes; ecc.Key.KB = k_bytes; string privKey = ecc.Key.PrivateKey; //Sign the payload using ES256 Jws jws = new Jws(); jws.Algorithm = JwsAlgorithms.jwsES256; jws.Certificate = new Certificate(CertStoreTypes.cstPEMKeyBlob, privKey, "", "*"); jws.InputMessage = "test"; jws.Sign(); string signedMessage = jws.OutputMessage; ``` **Notes for Unsecured (none)** To create a JWS token without any security set [Algorithm](#jwsalgorithm-property) to *jwsNone*. ```csharp Jws jws = new Jws(); jws.Algorithm = JwsAlgorithms.jwsNone; jws.InputMessage = "test"; jws.Sign(); string unsecuredMessage = jws.OutputMessage; ``` # [JWS](#jws-class).verify Method Verifies the signature of the JWS token. ## Syntax ```text async jws.verify(): Promise< void> ``` ## Remarks This method verifies the signature of the JWS token. Before calling the Verify method set [InputMessage](#jwsinputmessage-property) or [InputFile](#jwsinputfile-property) to a valid compact serialized JWS string. For instance: *eyJhbGciOiJIUzI1NiJ9.dGVzdA.o_JihJlCwvBO1AgY_Ao3_VBivdFmj3ufv3ZWAqYF4Ow* [Key](#jwskey-property) or [Certificate](#jwscertificate-property) should be set to the HMAC key or public certificate respectively. If the correct [Key](#jwskey-property) or [Certificate](#jwscertificate-property) is not known ahead of time the *KeyId* parameter of the [SignerInfo](#jwssignerinfo-event) event may be used to identify the correct key. If this method returns without error verification was successful. If verification fails then this method . After calling this method the payload will be present in the [OutputMessage](#jwsoutputmessage-property) or file specified by [OutputFile](#jwsoutputfile-property) and the [HeaderParams](#jwsheaderparams-property) property will contain the headers. Headers of the parsed message are also available through the [HeaderParam](#jwsheaderparam-event) event. The following properties are applicable when calling this method: - [Key](#jwskey-property) (conditional - required for HMAC) - [Certificate](#jwscertificate-property) (conditional - required for ECDSA and RSA) - [Algorithm](#jwsalgorithm-property) (only if [StrictValidation](#StrictValidation) is True) - [Overwrite](#jwsoverwrite-property) - [StrictValidation](#StrictValidation) **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: - [InputFile](#jwsinputfile-property) - [InputMessage](#jwsinputmessage-property) When a valid source is found, the search stops. The order in which the output properties are checked is as follows: - [OutputFile](#jwsoutputfile-property) - [OutputMessage](#jwsoutputmessage-property): The output data is written to this property if no other destination is specified. **Notes for HMAC Algorithms (HS256, HS384, HS512)** When verifying a message originally signed with a HMAC algorithm [Key](#jwskey-property) must be set to the same key used during signing. The key must be known by both parties in order for signing and verification to take place. ```csharp byte[] key = new byte[] { 170, 171, 221, 209, 7, 181, 48, 178, 48, 118, 242, 132, 36, 218, 74, 140, 216, 165, 161, 70, 11, 42, 246, 205, 235, 231, 19, 48, 87, 141, 122, 10 }; Jws jws = new Jws(); jws.KeyB = key; jws.InputMessage = signedData; jws.Verify(); string verifiedPayload = jws.OutputMessage; ``` **Notes for RSA Algorithms (RS256, RS384, RS512, PS256, PS384, PS512)** The RSA based algorithms use asymmetric encryption. Signing is done with a private key and verification is done with a public key. The public key is typically in PEM format. ```csharp Jws jws = new Jws(); jws.Certificate = new Certificate("..\\jwt.cer"); jws.InputMessage = signedData; jws.Verify(); string verifiedPayload = jws.OutputMessage; ``` **Notes for ECDSA Algorithms (ES256, ES384, ES512)** ECDSA algorithms require a valid ECC public key to verify the message. If the key was originally created with the [ECC](ECC.md#ECC) class the PEM encoded *PublicKey* may be used directly with the [Certificate](#jwscertificate-property) property. An example PEM encoded public certificate created by the [ECC](ECC.md#ECC) class: ```text -----BEGIN PUBLIC KEY----- MIIBMjCB7AYHKoZIzj0CATCB4AIBATAsBgcqhkjOPQEBAiEA/////wAAAAEAAAAAAAAAAAAA AAD///////////////8wRAQg/////wAAAAEAAAAAAAAAAAAAAAD///////////////wEIFrG NdiqOpPns+u9VXaYhrxlHQawzFOw9jvOPD4n0mBLBEEEaxfR8uEsQkf4vOblY6RA8ncDfYEt 6zOg9KE5RdiYwpZP40Li/hp/m47n60p8D54WK84zV2sxXs7LtkBoN79R9QIhAP////8AAAAA //////////+85vqtpxeehPO5ysL8YyVRAgEBA0EEIC5rbLp11Mnz6cBXLLriaDIov3rm8RAY x/OR0bOKiff0cQy+sLVaxjseqFk/+Xvl4ORSv5Z6HdHv5GyEpA0UoA== -----END PUBLIC KEY----- ``` ```csharp Jws jws = new Jws(); jws.Certificate = new Certificate(CertStoreTypes.cstPublicKeyFile, pubKey, "", "*"); jws.InputMessage = signedData; jws.Verify(); string verifiedPayload = jws.OutputMessage; ``` To use an ECC public key created by other means the [ECC](ECC.md#ECC) class may be used to import the key parameters. Populate the *Rx* and *Ry* of the [ECC](ECC.md#ECC) class first to obtain the PEM formatted public key. For instance: ```csharp //Import an existing ECC public key Ecc ecc = new Ecc(); byte[] x_bytes = new byte[] { 171, 170, 196, 151, 94, 196, 231, 12, 128, 232, 17, 61, 45, 105, 41, 209, 192, 187, 112, 242, 110, 178, 95, 240, 36, 55, 83, 171, 190, 176, 78, 13 }; byte[] y_bytes = new byte[] { 197, 75, 134, 245, 245, 28, 199, 9, 7, 117, 1, 54, 49, 178, 135, 252, 62, 89, 35, 180, 117, 80, 231, 23, 110, 250, 28, 124, 219, 253, 224, 156 }; ecc.Key.RxB = x_bytes; ecc.Key.RyB = y_bytes; string pubKey = ecc.Key.PublicKey; Jws jws = new Jws(); jws.Certificate = new Certificate(CertStoreTypes.cstPublicKeyFile, pubKey, "", "*"); jws.InputMessage = signedData; jws.Verify(); string verifiedPayload = jws.OutputMessage; ``` **Notes for Unsecured (none)** To parse a JWS token without any security call the [Sign](#jwssign-method) method without setting [Key](#jwskey-property) or [Certificate](#jwscertificate-property). ```csharp Jws jws = new Jws(); jws.InputMessage = signedData; jws.Verify(); string unsecuredPayload = jws.OutputMessage; ``` # [JWS](#jws-class).Error Event Fired when information is available about errors during data delivery. ## Syntax ```text jws.on('Error', listener: (e: {readonly errorCode: number, readonly description: string}) => void ) ``` ## Remarks The Error event is fired in case of exceptional conditions during message processing. Normally the class . 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-class-ipworksencryptjws) section. # [JWS](#jws-class).HeaderParam Event Fires once for each JOSE header parameter. ## Syntax ```text jws.on('HeaderParam', listener: (e: {readonly name: string, readonly value: string, readonly dataType: number}) => void ) ``` ## Remarks When [Verify](#jwsverify-method) or [Parse](#jwsparse-method) is called this event will fire once for each JOSE header parameter. *Name* is the name of the parameter. *Value* is the value of the parameter. *DataType* specifies the JSON data type of the value. Possible values are: - 0 (Object) - 1 (Array) - 2 (String) - 3 (Number) - 4 (Bool) - 5 (Null) # [JWS](#jws-class).SignerInfo Event Fires with information about the signature. ## Syntax ```text jws.on('SignerInfo', listener: (e: {readonly keyId: string, readonly algorithm: string}) => void ) ``` ## Remarks This event fires with information about the signature. This may be used to help identify the [Key](#jwskey-property) or [Certificate](#jwscertificate-property) to load in order to verify the signature. This event fires when [Verify](#jwsverify-method) or [Parse](#jwsparse-method) is called. *KeyId* is the Id of the key as supplied by the signer that created the message. This may be empty. *Algorithm* is the signature algorithm used to sign the message. # Certificate Type This is the digital certificate being used. ## Remarks This type describes the current digital certificate. The certificate may be a public or private key. The fields are used to identify or select certificates. The following fields are available: - [EffectiveDate](#Certificate_f_EffectiveDate) - [ExpirationDate](#Certificate_f_ExpirationDate) - [ExtendedKeyUsage](#Certificate_f_ExtendedKeyUsage) - [Fingerprint](#Certificate_f_Fingerprint) - [FingerprintSHA1](#Certificate_f_FingerprintSHA1) - [FingerprintSHA256](#Certificate_f_FingerprintSHA256) - [Issuer](#Certificate_f_Issuer) - [KeyPassword](#Certificate_f_KeyPassword) - [PrivateKey](#Certificate_f_PrivateKey) - [PrivateKeyAvailable](#Certificate_f_PrivateKeyAvailable) - [PrivateKeyContainer](#Certificate_f_PrivateKeyContainer) - [PublicKey](#Certificate_f_PublicKey) - [PublicKeyAlgorithm](#Certificate_f_PublicKeyAlgorithm) - [PublicKeyLength](#Certificate_f_PublicKeyLength) - [SerialNumber](#Certificate_f_SerialNumber) - [SignatureAlgorithm](#Certificate_f_SignatureAlgorithm) - [Store](#Certificate_f_Store) - [StorePassword](#Certificate_f_StorePassword) - [StoreType](#Certificate_f_StoreType) - [SubjectAltNames](#Certificate_f_SubjectAltNames) - [ThumbprintMD5](#Certificate_f_ThumbprintMD5) - [ThumbprintSHA1](#Certificate_f_ThumbprintSHA1) - [ThumbprintSHA256](#Certificate_f_ThumbprintSHA256) - [Usage](#Certificate_f_Usage) - [UsageFlags](#Certificate_f_UsageFlags) - [Version](#Certificate_f_Version) - [Subject](#Certificate_f_Subject) - [Encoded](#Certificate_f_Encoded) ## Fields **EffectiveDate** *string (read-only)* *Default Value: ""* The date on which this certificate becomes valid. Before this date, it is not valid. The date is localized to the system's time zone. The following example illustrates the format of an encoded date: 23-Jan-2000 15:00:00. **ExpirationDate** *string (read-only)* *Default Value: ""* The date on which the certificate expires. After this date, the certificate will no longer be valid. The date is localized to the system's time zone.

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](#jwsconfig-method) method. ### JWS Config Settings **AllowedSigningAlgorithms**: Allowed signing algorithms when StrictValidation is set to True.This setting specifics a comma separated list of algorithms that are allowed when [StrictValidation](#StrictValidation) is set to *true*. This allows multiple signing algorithms to be considered acceptable during validation. This setting is only applicable when [StrictValidation](#StrictValidation) is set to *true*. Possible values: - *HS256* - *HS384* - *HS512* - *RS256* - *RS384* - *RS512* - *ES256* - *ES384* - *ES512* - *PS256* - *PS384* - *PS512* Example value: *HS512,HS256*. **IncludeCertificateFormat**: The certificate values to include in the signed message (if any).This setting specifies whether information about the [Certificate](#jwscertificate-property) is included in the signed message. When specified, the value here determines the format of the included certificate information. The certificate information is included as a standard JWS header parameter. Multiple formats may be included in the signed message. The value specified should be the binary 'OR' of one or more of the following values: | Value | Description | JWS Header Param | | --- | --- | --- | | 0 (0x00 - default) | None | | | 1 (0x01) | X.509 Certificate Chain | x5c | | 2 (0x02) | X.509 Certificate SHA-1 Thumbprint (Base64-URL encoded) | x5t | | 4 (0x04) | X.509 Certificate SHA-256 Thumbprint (Base64-URL encoded) | x5t#S256 | Note: When including the certificate chain (*0x01*) the public certificate of [Certificate](#jwscertificate-property) property will automatically be included. [IssuerCerts](#IssuerCerts) may also be set to the public issuer certificates that will be used when building the chain to include. For instance, to include both the certificate chain and SHA-256 thumbprint of the [Certificate](#jwscertificate-property) set this to *5*. **IssuerCerts**: A collection of issuer certificates used with IncludeCertificateFormat.This setting optionally specifies one or more issuer certificates that may be used by the class when [IncludeCertificateFormat](#IncludeCertificateFormat) is specified. Note that the issuer certificates specified here are used as a store of potential issuer certificates. At runtime the class will inspect the [Certificate](#jwscertificate-property) value and add the relevant issuer certificates that are present in this property. The format of the value must be one or more PEM encoded certificates with headers and footers. For instance to include 2 issuer certificates the value may be: ```text -----BEGIN CERTIFICATE----- MIIBujCCASOgAwIBAgICA+kwDQYJKoZIhvcNAQELBQAwHTEbMBkGA1UEAxMSbnVuaXRDZXJ0 Q2hhaW5Sb290MCAXDTE4MTAxNTA5MDAxN1oYDzIxMTgwOTIxMDkwMDE3WjAmMSQwIgYDVQQD ...

The [Key](#jwskey-property) is typically represented as an array of bytes, however in some cases the key value may have been encoded. As a matter of convenience the class will accept the key with an encoding already applied. The class will decode the key value according the to the value specified here before processing. Possible values are: - 0 (none - default) - 1 (Base64) - 2 (Hex) - 3 (Base64URL) **RawHeader**: Holds the raw JOSE header.This setting may be queried after calling [Sign](#jwssign-method) or [Verify](#jwsverify-method) to obtain the raw JOSE header. This returns a JSON string like: *{"alg":"ES384","kid":"myKeyId"}* **SerializationType**: Determines the serialization type to use when reading and writing JWS content.This setting is used to control the serialization type the class uses when reading and writing JWS content. Possible values are: - *0* *(default)*: Compact serialization (content is serialized as a single base64url-encoded string). - *1*: Standard JSON serialization. - *2*: Flattened JSON serialization. **StrictValidation**: Requires a specific algorithm when verifying signatures.If set to True the class will validate that the Algorithm in the JWS message matches the value specified in the [Algorithm](#jwsalgorithm-property) property. If it does not an error is thrown. By default this is False and the algorithm is read and used automatically from the message. Enabling this setting provides a way to require a specific algorithm when calling VerifySignature. ### 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 class will use the system security libraries by default to perform cryptographic functions where applicable. Setting this configuration setting to *true* tells the class to use the internal implementation instead of using the system security libraries. This setting is set to *false* by default on all platforms. # Trappable Errors (*class *ipworksencrypt.[jws](#jws-class)) ### JWS Errors | | | | --- | --- | | 201 | Invalid JWS value.
