Syntax

JWS

Remarks

The JWS class supports signing and verifying JSON Web Signatures (JWS).

Specify any payload via input properties and use Sign to create a JWS message using a variety of algorithms including HMAC, RSA, and ECDSA. Use Verify 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 for more details about supported algorithms.

Signing

The Sign method may be used to sign a payload with a variety of algorithms. Before calling the Sign method set Algorithm 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 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 (required)
• Certificate (conditional - required for ECDSA and RSA)
• Key (conditional - required for HMAC)
• HeaderParams
• KeyId
• Overwrite

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:

• SetInputStream
• InputFile
• InputMessage

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

• SetOutputStream
• OutputFile
• OutputMessage: The output data is written to this property if no other destination is specified.

When using streams, you may need to additionally set CloseInputStreamAfterProcessing or CloseOutputStreamAfterProcessing.

Notes for HMAC Algorithms (HS256, HS384, HS512)

When Algorithm is set to a HMAC algorithm Key must be set to a key of appropriate length for the algorithm. The Key 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 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.

//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 property. For instance:

//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.

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 class can be used to create or import an ECC key into the Certificate format accepted by the JWS class.

//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 class first. For instance:

//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 to jwsNone.

Jws jws = new Jws(); jws.Algorithm = JwsAlgorithms.jwsNone; jws.InputMessage = "test"; jws.Sign(); string unsecuredMessage = jws.OutputMessage;

Signature Verification

The Verify method may be used to verify a received JWS message. Before calling the Verify method set InputMessage or InputFile to a valid compact serialized JWS string. For instance:

eyJhbGciOiJIUzI1NiJ9.dGVzdA.o_JihJlCwvBO1AgY_Ao3_VBivdFmj3ufv3ZWAqYF4Ow

Key or Certificate should be set to the HMAC key or public certificate respectively. If the correct Key or Certificate is not known ahead of time the KeyId parameter of the SignerInfo event may be used to identify the correct key.

If this method returns without error verification was successful. If verification fails then this method fails with an error. After calling this method the payload will be present in the OutputMessage or file specified by OutputFile and the HeaderParams property will contain the headers. Headers of the parsed message are also available through the HeaderParam event.

The following properties are applicable when calling this method:

• Key (conditional - required for HMAC)
• Certificate (conditional - required for ECDSA and RSA)
• Algorithm (only if StrictValidation is True)
• Overwrite
• 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:

• SetInputStream
• InputFile
• InputMessage

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

• SetOutputStream
• OutputFile
• OutputMessage: The output data is written to this property if no other destination is specified.

When using streams, you may need to additionally set CloseInputStreamAfterProcessing or CloseOutputStreamAfterProcessing.

Notes for HMAC Algorithms (HS256, HS384, HS512)

When verifying a message originally signed with a HMAC algorithm Key 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.

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.

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 class the PEM encoded PublicKey may be used directly with the Certificate property. An example PEM encoded public certificate created by the ECC class:

-----BEGIN PUBLIC KEY-----

-----END PUBLIC KEY-----

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 class may be used to import the key parameters. Populate the Rx and Ry of the ECC class first to obtain the PEM formatted public key. For instance:

//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 method without setting Key or Certificate.

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
• Enforcing algorithm restrictions when verifying by setting StrictValidation
• Inspect the JWS without verifying by calling Parse

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 is it first hashed with the same algorithm.

Remarks

This property indicates whether or not the class will overwrite OutputFile. If Overwrite is False, an error will be thrown whenever OutputFile exists before an operation. The default value is False.

Data Type

Boolean

AddHeaderParam Method (JWS Class)

Adds additional header parameters.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int AddHeaderParam(const char* lpszname, const char* lpszvalue, int idataType);

Unicode (Windows)
INT AddHeaderParam(LPCWSTR lpszname, LPCWSTR lpszvalue, INT idataType);

int ipworksencrypt_jws_addheaderparam(void* lpObj, const char* lpszname, const char* lpszvalue, int idataType);

int AddHeaderParam(const QString& qsname, const QString& qsvalue, int idataType);

Remarks

This method is used to add additional header parameters before calling Sign.

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)

{
  "alg": "HS512",
  "crit": [
    "exp"
  ],
  "exp": 12345687,
  "kid": "myKeyId",
  "type": "JWT"
}

The following code can be used:

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 the class will automatically add some headers based on properties that are set.

Parameters Automatically Set:

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

Config Method (JWS Class)

Sets or retrieves a configuration setting.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
char* Config(const char* lpszConfigurationString);

Unicode (Windows)
LPWSTR Config(LPCWSTR lpszConfigurationString);

char* ipworksencrypt_jws_config(void* lpObj, const char* lpszConfigurationString);

QString Config(const QString& qsConfigurationString);

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.

Error Handling (C++)

This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

Parse Method (JWS Class)

Parses the compact serialized JWS string.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int Parse();

Unicode (Windows)
INT Parse();

int ipworksencrypt_jws_parse(void* lpObj);

int Parse();

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 instead. It is not necessary to call this method before calling Verify. Verify will both parse and verify the message.

When calling this method the headers and payload are parsed. The HeaderParam and SignerInfo events will fire and the HeaderParams 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:

• SetInputStream
• InputFile
• InputMessage

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

• SetOutputStream
• OutputFile
• OutputMessage: The output data is written to this property if no other destination is specified.

When using streams, you may need to additionally set CloseInputStreamAfterProcessing or CloseOutputStreamAfterProcessing.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

Reset Method (JWS Class)

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int Reset();

Unicode (Windows)
INT Reset();

int ipworksencrypt_jws_reset(void* lpObj);

int Reset();

Remarks

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

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

SetInputStream Method (JWS Class)

Sets the stream from which the class will read data.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int SetInputStream(IPWorksEncryptStream* sInputStream);

Unicode (Windows)
INT SetInputStream(IPWorksEncryptStream* sInputStream);

int ipworksencrypt_jws_setinputstream(void* lpObj, IPWorksEncryptStream* sInputStream);

int SetInputStream(IPWorksEncryptStream* sInputStream);

Remarks

This method may be used to set a stream from which data will be read.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int SetOutputStream(IPWorksEncryptStream* sOutputStream);

Unicode (Windows)
INT SetOutputStream(IPWorksEncryptStream* sOutputStream);

int ipworksencrypt_jws_setoutputstream(void* lpObj, IPWorksEncryptStream* sOutputStream);

int SetOutputStream(IPWorksEncryptStream* sOutputStream);

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:

• SetInputStream
• InputFile
• InputMessage

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

• SetOutputStream

• OutputMessage: The output data is written to this property if no other destination is specified.

When using streams, you may need to additionally set CloseInputStreamAfterProcessing or CloseOutputStreamAfterProcessing.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

Sign Method (JWS Class)

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int Sign();

Unicode (Windows)
INT Sign();

int ipworksencrypt_jws_sign(void* lpObj);

int Sign();

Remarks

This method signs the input with the specified Algorithm.

Before calling the Sign method set Algorithm 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 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 (required)
• Certificate (conditional - required for ECDSA and RSA)
• Key (conditional - required for HMAC)
• HeaderParams
• KeyId
• Overwrite

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:

• SetInputStream
• InputFile
• InputMessage

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

• SetOutputStream
• OutputFile
• OutputMessage: The output data is written to this property if no other destination is specified.

When using streams, you may need to additionally set CloseInputStreamAfterProcessing or CloseOutputStreamAfterProcessing.

Notes for HMAC Algorithms (HS256, HS384, HS512)

When Algorithm is set to a HMAC algorithm Key must be set to a key of appropriate length for the algorithm. The Key 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 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.

//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 property. For instance:

//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.

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 class can be used to create or import an ECC key into the Certificate format accepted by the JWS class.

//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 class first. For instance:

//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 to jwsNone.

Jws jws = new Jws(); jws.Algorithm = JwsAlgorithms.jwsNone; jws.InputMessage = "test"; jws.Sign(); string unsecuredMessage = jws.OutputMessage;

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

Verify Method (JWS Class)

Verifies the signature of the JWS token.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int Verify();

Unicode (Windows)
INT Verify();

int ipworksencrypt_jws_verify(void* lpObj);

int Verify();

Remarks

This method verifies the signature of the JWS token.

Before calling the Verify method set InputMessage or InputFile to a valid compact serialized JWS string. For instance:

eyJhbGciOiJIUzI1NiJ9.dGVzdA.o_JihJlCwvBO1AgY_Ao3_VBivdFmj3ufv3ZWAqYF4Ow

Key or Certificate should be set to the HMAC key or public certificate respectively. If the correct Key or Certificate is not known ahead of time the KeyId parameter of the SignerInfo event may be used to identify the correct key.

If this method returns without error verification was successful. If verification fails then this method fails with an error. After calling this method the payload will be present in the OutputMessage or file specified by OutputFile and the HeaderParams property will contain the headers. Headers of the parsed message are also available through the HeaderParam event.

The following properties are applicable when calling this method:

• Key (conditional - required for HMAC)
• Certificate (conditional - required for ECDSA and RSA)
• Algorithm (only if StrictValidation is True)
• Overwrite
• 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:

• SetInputStream
• InputFile
• InputMessage

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

• SetOutputStream
• OutputFile
• OutputMessage: The output data is written to this property if no other destination is specified.

When using streams, you may need to additionally set CloseInputStreamAfterProcessing or CloseOutputStreamAfterProcessing.

Notes for HMAC Algorithms (HS256, HS384, HS512)

When verifying a message originally signed with a HMAC algorithm Key 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.

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.

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 class the PEM encoded PublicKey may be used directly with the Certificate property. An example PEM encoded public certificate created by the ECC class:

-----BEGIN PUBLIC KEY-----
MIIBMjCB7AYHKoZIzj0CATCB4AIBATAsBgcqhkjOPQEBAiEA/////wAAAAEAAAAAAAAAAAAA

-----END PUBLIC KEY-----

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 class may be used to import the key parameters. Populate the Rx and Ry of the ECC class first to obtain the PEM formatted public key. For instance:

//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 method without setting Key or Certificate.

Jws jws = new Jws(); jws.InputMessage = signedData; jws.Verify(); string unsecuredPayload = jws.OutputMessage;

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
