See EncryptionAlgorithm for more details about supported algorithms.
Encrypting
The Encrypt method may be used to encrypt a payload with a variety of algorithms. JSON Web Encryption (JWE) is performed by first generating a random key used to encrypt the content. The content encryption key is used to encrypt the content using the algorithm specified by ContentEncryptionAlgorithm. The content encryption key is then encrypted itself using the algorithm specified by EncryptionAlgorithm. The content encryption key is not directly exposed in the API as it is randomly generated.
After calling this method the compact serialized JWE string is written to the specified output location. For instance:
eyJhbGciOiJBMjU2R0NNS1ciLCJlbmMiOiJBMTI4Q0JDLUhTMjU2IiwiaXYiOiJMa0tNeTZ5Qlpfbzh6QW92IiwidGFnIjoiSmpMTkRsV3l3bWt3V2pMa0NLU0xxQSJ9.wiwySYm6fXZre-3IdT1tb_02KMQDrMICwUawVf7Gjhc.k84s7ne8J41QnA5BQ31k_A.kjIveRjjNYV4x92CVE9Agw.uAygkyeO2KWeFQIy9JLU0A
The class is agnostic of the payload that is encrypted. Any value may be encrypted. KeyId may be set to include an identifier to help the receiving party identify the key or certificate used to encrypt the data. The following properties are applicable when calling this method:
- EncryptionAlgorithm (required)
- Key (conditional - required for AES)
- KeyPassword (conditional - required for PBES)
- Certificate (conditional - required for ECDH and RSA)
- ContentEncryptionAlgorithm
- CompressionAlgorithm
- Header*
- 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:
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 AES Algorithms (A128KW, A192KW, A256KW, A128GCMKW, A192GCMKW, A256GCMKW)
When EncryptionAlgorithm is set to a AES algorithm Key must be set to a key of appropriate length for the algorithm. For instance a 256 bit key would be used for A256KW.
The example below uses the EzRand class to generate a key, but the key may be created using any method. The key must be known by both parties in order for encryption and decryption to take place.
//Generate a 256 bit (32 byte) key
Ezrand rand = new Ezrand();
rand.RandBytesLength = 32;
rand.GetNextBytes();
byte[] key = rand.RandBytesB;
//Encrypt the payload using A256KW
Jwe jwe = new Jwe();
jwe.KeyB = key;
jwe.InputMessage = "test data";
jwe.EncryptionAlgorithm = JweEncryptionAlgorithms.eaA256KW;
jwe.Encrypt();
string encryptedData = jwe.OutputMessage;
To use an existing AES key provide the bytes to the Key property. For instance:
byte[] key = new byte[] { 164, 60, 194, 0, 161, 189, 41, 38, 130, 89, 141, 164, 45, 170, 159, 209, 69, 137, 243, 216, 191, 131, 47, 250, 32, 107, 231, 117, 37, 158, 225, 234 };
//Encrypt the payload using A256KW
Jwe jwe = new Jwe();
jwe.KeyB = key;
jwe.InputMessage = "test data";
jwe.EncryptionAlgorithm = JweEncryptionAlgorithms.eaA256KW;
jwe.Encrypt();
string encryptedData = jwe.OutputMessage;
Notes for RSA Algorithms (RSA1_5, RSA-OEAP, RSA-OAEP-256)
The RSA based algorithms use asymmetric encryption. Encrypting is done with a public key and decryption is done with a private key. The public certificate should be in PEM (base64) format. For instance:
Jwe jwe = new Jwe();
jwe.Certificate = new Certificate("..\\recipient.cer");
jwe.InputMessage = "test data";
jwe.EncryptionAlgorithm = JweEncryptionAlgorithms.eaRSA_OAEP;
jwe.Encrypt();
string encryptedData = jwe.OutputMessage;
Notes for ECDH Algorithms (ECDH-ES, ECDH-ES+A128KW, ECDH-ES+A192KW, ECDH-ES+A256KW)
ECDH algorithms require a valid ECC public key to encrypt 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 component:
-----BEGIN PUBLIC KEY----- MIIBMjCB7AYHKoZIzj0CATCB4AIBATAsBgcqhkjOPQEBAiEA/////wAAAAEAAAAAAAAAAAAA AAD///////////////8wRAQg/////wAAAAEAAAAAAAAAAAAAAAD///////////////wEIFrG NdiqOpPns+u9VXaYhrxlHQawzFOw9jvOPD4n0mBLBEEEaxfR8uEsQkf4vOblY6RA8ncDfYEt 6zOg9KE5RdiYwpZP40Li/hp/m47n60p8D54WK84zV2sxXs7LtkBoN79R9QIhAP////8AAAAA //////////+85vqtpxeehPO5ysL8YyVRAgEBA0EEIC5rbLp11Mnz6cBXLLriaDIov3rm8RAY x/OR0bOKiff0cQy+sLVaxjseqFk/+Xvl4ORSv5Z6HdHv5GyEpA0UoA== -----END PUBLIC KEY-----
Jwe jwe = new Jwe();
jwe.Certificate = new Certificate(CertStoreTypes.cstPublicKeyFile, pubKeyFile, "", "*");
jwe.InputMessage = "test data";
jwe.EncryptionAlgorithm = JweEncryptionAlgorithms.eaECDH_ES_A256KW;
jwe.Encrypt();
string encryptedData = jwe.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 properties of the ECC component first to obtain the PEM formatted public key. For instance:
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 ecc = new Ecc();
ecc.Key.RxB = x_bytes;
ecc.Key.RyB = y_bytes;
string pubKey = ecc.Key.PublicKey;
Jwe jwe = new Jwe();
jwe.Certificate = new Certificate(CertStoreTypes.cstPublicKeyFile, pubKey, "", "*");
jwe.InputMessage = "test data";
jwe.EncryptionAlgorithm = JweEncryptionAlgorithms.eaECDH_ES_A256KW;
jwe.Encrypt();
string encryptedData = jwe.OutputMessage;
Notes for PBES Algorithms (PBES2-HS256+A128KW, PBES2-HS384+A192KW, PBES2-HS512+A256KW
PBES algorithms derive a content encryption key from the KeyPassword property. Set KeyPassword to a shared secret.
Jwe jwe = new Jwe();
jwe.KeyPassword = "secret";
jwe.InputMessage = "test data";
jwe.EncryptionAlgorithm = JweEncryptionAlgorithms.eaPBES2_HS512_A256KW;
jwe.Encrypt();
string encryptedData = jwe.OutputMessage;
Notes for Direct Shared Keys
When EncryptionAlgorithm is set to Direct the Key property must be set to a valid symmetric key that will be used directly by the ContentEncryptionAlgorithm. In this case a content encryption key is not generated randomly, the Key is used instead. The length of the specified Key must be valid for the selected ContentEncryptionAlgorithm. For instance:
//Generate a 256 bit (32 byte) key
Ezrand rand = new Ezrand();
rand.RandBytesLength = 32;
rand.GetNextBytes();
byte[] key = rand.RandBytesB;
Jwe jwe = new Jwe();
jwe.EncryptionAlgorithm = JweEncryptionAlgorithms.eaDir;
jwe.ContentEncryptionAlgorithm = JweContentEncryptionAlgorithms.ceaA256GCM;
jwe.KeyB = key;
jwe.InputMessage = "test data";
jwe.Encrypt();
string encryptedData = jwe.OutputMessage;
Decrypting
The Decrypt method may be used to decrypt a received JWE message. Before calling the Decrypt method set InputMessage or InputFile to a valid compact serialized JWE string. For instance:
eyJhbGciOiJBMjU2R0NNS1ciLCJlbmMiOiJBMTI4Q0JDLUhTMjU2IiwiaXYiOiJMa0tNeTZ5Qlpfbzh6QW92IiwidGFnIjoiSmpMTkRsV3l3bWt3V2pMa0NLU0xxQSJ9.wiwySYm6fXZre-3IdT1tb_02KMQDrMICwUawVf7Gjhc.k84s7ne8J41QnA5BQ31k_A.kjIveRjjNYV4x92CVE9Agw.uAygkyeO2KWeFQIy9JLU0A
The type and format of the private key depends on the algorithm used to encrypt the data. The following table summarizes the relationship:
Algorithm | Private Key Location |
AES | Key |
RSA and ECDH | Certificate |
PBES | KeyPassword |
If this method returns without error decryption was successful. If decryption 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 Header* properties 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:
- Certificate (conditional - required for RSA and ECDH)
- Key (conditional - required for AES)
- ContentEncryptionAlgorithm (only if StrictValidation is True)
- EncryptionAlgorithm (only if StrictValidation is True)
- Header*
- 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:
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 AES Algorithms (A128KW, A192KW, A256KW, A128GCMKW, A192GCMKW, A256GCMKW)
To decrypt messages that use AES encryption Key must be set to a key of appropriate length for the algorithm. For instance a 256 bit key would be used for A256KW.
The key must be known by both parties in order for encryption and decryption to take place.
byte[] key = new byte[] { 164, 60, 194, 0, 161, 189, 41, 38, 130, 89, 141, 164, 45, 170, 159, 209, 69, 137, 243, 216, 191, 131, 47, 250, 32, 107, 231, 117, 37, 158, 225, 234 };
Jwe jwe = new Jwe();
jwe.KeyB = key;
jwe.InputMessage = encryptedData;
jwe.Decrypt();
string decryptedData = jwe.OutputMessage;
Notes for RSA Algorithms (RSA1_5, RSA-OEAP, RSA-OAEP-256)
The RSA based algorithms use asymmetric encryption. Encrypting is done with a public key and decryption is done with a private key. The certificate with private key must be specified. For instance:
Jwe jwe = new Jwe();
jwe.Certificate = new Certificate(CertStoreTypes.cstPFXFile, "..\\jwt.pfx", "password", "*");
jwe.InputMessage = encryptedData;
jwe.Decrypt();
string decryptedData = jwe.OutputMessage;
Notes for ECDH Algorithms (ECDH-ES, ECDH-ES+A128KW, ECDH-ES+A192KW, ECDH-ES+A256KW)
ECDH algorithms require a valid ECC private key to decrypt the message. If the key was originally created with the ECC class the PEM encoded PrivateKey may be used directly with the Certificate property.
Jwe jwe = new Jwe();
jwe.Certificate = new Certificate(CertStoreTypes.cstPEMKeyFile, privKeyFile, "", "*");
jwe.InputMessage = encryptedData;
jwe.Decrypt();
string decryptedData = jwe.OutputMessage;
To use an ECC private key created by other means the ECC class may be used to import the key parameters. Populate the Rx, Ry, and KB properties of the ECC component first to obtain the PEM formatted public key. For instance:
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;
Jwe jwe = new Jwe();
jwe.Certificate = new Certificate(CertStoreTypes.cstPEMKeyBlob, privKey, "", "*");
jwe.InputMessage = encryptedData;
jwe.Decrypt();
string decryptedData = jwe.OutputMessage;
Notes for PBES Algorithms (PBES2-HS256+A128KW, PBES2-HS384+A192KW, PBES2-HS512+A256KW
PBES algorithms derive a content encryption key from the KeyPassword property. Set KeyPassword to the shared secret.
Jwe jwe = new Jwe();
jwe.KeyPassword = "secret";
jwe.InputMessage = encryptedData;
jwe.Decrypt();
string decryptedData = jwe.OutputMessage;
Notes for Direct Shared Keys
When Direct encryption is used the Key property must be set to a valid symmetric key that will be used directly by the ContentEncryptionAlgorithm. For instance:
byte[] key = new byte[] { 164, 60, 194, 0, 161, 189, 41, 38, 130, 89, 141, 164, 45, 170, 159, 209, 69, 137, 243, 216, 191, 131, 47, 250, 32, 107, 231, 117, 37, 158, 225, 234 };
Jwe jwe = new Jwe();
jwe.KeyB = key;
jwe.InputMessage = encryptedData;
jwe.Decrypt();
string decryptedData = jwe.OutputMessage;
Other Functionality

Note: This store type is only available in Java and .NET. |
23 (cstPKCS11) | The certificate is present on a physical security key accessible via a PKCS#11 interface.
To use a security key, the necessary data must first be collected using the CertMgr class. The ListStoreCertificates method may be called after setting CertStoreType to cstPKCS11, CertStorePassword to the PIN, and CertStore to the full path of the PKCS#11 DLL. The certificate information returned in the CertList event's CertEncoded parameter may be saved for later use. When using a certificate, pass the previously saved security key information as the CertStore and set CertStorePassword to the PIN. Code Example. SSH Authentication with Security Key:

QString GetCertSubject();
int SetCertSubject(QString qsCertSubject);
Default Value
""
Remarks
This is the subject of the certificate used for client authentication.
This property must be set after all other certificate properties are set. When this property is set, a search is performed in the current certificate store to locate a certificate with a matching subject.
If a matching certificate is found, the property is set to the full subject of the matching certificate.
If an exact match is not found, the store is searched for subjects containing the value of the property.
If a match is still not found, the property is set to an empty string, and no certificate is selected.
The special value "*" picks a random certificate in the certificate store.
The certificate subject is a comma-separated list of distinguished name fields and values. For instance, "CN=www.server.com, OU=test, C=US, E=support@nsoftware.com". Common fields and their meanings are as follows:
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.

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 (JWE Class)
Sets or retrieves a configuration setting.
Syntax
ANSI (Cross Platform) char* Config(const char* lpszConfigurationString); Unicode (Windows) LPWSTR Config(LPCWSTR lpszConfigurationString);
char* ipworksencrypt_jwe_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.
Decrypt Method (JWE Class)
Decrypts the payload.
Syntax
ANSI (Cross Platform) int Decrypt(); Unicode (Windows) INT Decrypt();
int ipworksencrypt_jwe_decrypt(void* lpObj);
int Decrypt();
Remarks
This method decrypts the input data.
Before calling the Decrypt method set InputMessage or InputFile to a valid compact serialized JWE string. For instance:
eyJhbGciOiJBMjU2R0NNS1ciLCJlbmMiOiJBMTI4Q0JDLUhTMjU2IiwiaXYiOiJMa0tNeTZ5Qlpfbzh6QW92IiwidGFnIjoiSmpMTkRsV3l3bWt3V2pMa0NLU0xxQSJ9.wiwySYm6fXZre-3IdT1tb_02KMQDrMICwUawVf7Gjhc.k84s7ne8J41QnA5BQ31k_A.kjIveRjjNYV4x92CVE9Agw.uAygkyeO2KWeFQIy9JLU0A
The type and format of the private key depends on the algorithm used to encrypt the data. The following table summarizes the relationship:
Algorithm | Private Key Location |
AES | Key |
RSA and ECDH | Certificate |
PBES | KeyPassword |
If this method returns without error decryption was successful. If decryption 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 Header* properties 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:
- Certificate (conditional - required for RSA and ECDH)
- Key (conditional - required for AES)
- ContentEncryptionAlgorithm (only if StrictValidation is True)
- EncryptionAlgorithm (only if StrictValidation is True)
- Header*
- 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:
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 AES Algorithms (A128KW, A192KW, A256KW, A128GCMKW, A192GCMKW, A256GCMKW)
To decrypt messages that use AES encryption Key must be set to a key of appropriate length for the algorithm. For instance a 256 bit key would be used for A256KW.
The key must be known by both parties in order for encryption and decryption to take place.
byte[] key = new byte[] { 164, 60, 194, 0, 161, 189, 41, 38, 130, 89, 141, 164, 45, 170, 159, 209, 69, 137, 243, 216, 191, 131, 47, 250, 32, 107, 231, 117, 37, 158, 225, 234 };
Jwe jwe = new Jwe();
jwe.KeyB = key;
jwe.InputMessage = encryptedData;
jwe.Decrypt();
string decryptedData = jwe.OutputMessage;
Notes for RSA Algorithms (RSA1_5, RSA-OEAP, RSA-OAEP-256)
The RSA based algorithms use asymmetric encryption. Encrypting is done with a public key and decryption is done with a private key. The certificate with private key must be specified. For instance:
Jwe jwe = new Jwe();
jwe.Certificate = new Certificate(CertStoreTypes.cstPFXFile, "..\\jwt.pfx", "password", "*");
jwe.InputMessage = encryptedData;
jwe.Decrypt();
string decryptedData = jwe.OutputMessage;
Notes for ECDH Algorithms (ECDH-ES, ECDH-ES+A128KW, ECDH-ES+A192KW, ECDH-ES+A256KW)
ECDH algorithms require a valid ECC private key to decrypt the message. If the key was originally created with the ECC class the PEM encoded PrivateKey may be used directly with the Certificate property.
Jwe jwe = new Jwe();
jwe.Certificate = new Certificate(CertStoreTypes.cstPEMKeyFile, privKeyFile, "", "*");
jwe.InputMessage = encryptedData;
jwe.Decrypt();
string decryptedData = jwe.OutputMessage;
To use an ECC private key created by other means the ECC class may be used to import the key parameters. Populate the Rx, Ry, and KB properties of the ECC component first to obtain the PEM formatted public key. For instance:

Notes for PBES Algorithms (PBES2-HS256+A128KW, PBES2-HS384+A192KW, PBES2-HS512+A256KW
PBES algorithms derive a content encryption key from the KeyPassword property. Set KeyPassword to the shared secret.
Jwe jwe = new Jwe();
jwe.KeyPassword = "secret";
jwe.InputMessage = encryptedData;
jwe.Decrypt();
string decryptedData = jwe.OutputMessage;
Notes for Direct Shared Keys
When Direct encryption is used the Key property must be set to a valid symmetric key that will be used directly by the ContentEncryptionAlgorithm. For instance:
byte[] key = new byte[] { 164, 60, 194, 0, 161, 189, 41, 38, 130, 89, 141, 164, 45, 170, 159, 209, 69, 137, 243, 216, 191, 131, 47, 250, 32, 107, 231, 117, 37, 158, 225, 234 };
Jwe jwe = new Jwe();
jwe.KeyB = key;
jwe.InputMessage = encryptedData;
jwe.Decrypt();
string decryptedData = jwe.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.)
Encrypt Method (JWE Class)
Encrypts the payload with the specified algorithms.
Syntax
ANSI (Cross Platform) int Encrypt(); Unicode (Windows) INT Encrypt();
int ipworksencrypt_jwe_encrypt(void* lpObj);
int Encrypt();
Remarks
This method encrypts the input data using the specified algorithms.
JSON Web Encryption (JWE) is performed by first generating a random key used to encrypt the content. The content encryption key is used to encrypt the content using the algorithm specified by ContentEncryptionAlgorithm. The content encryption key is then encrypted itself using the algorithm specified by EncryptionAlgorithm. The content encryption key is not directly exposed in the API as it is randomly generated.
After calling this method the compact serialized JWE string is written to the specified output location. For instance:
eyJhbGciOiJBMjU2R0NNS1ciLCJlbmMiOiJBMTI4Q0JDLUhTMjU2IiwiaXYiOiJMa0tNeTZ5Qlpfbzh6QW92IiwidGFnIjoiSmpMTkRsV3l3bWt3V2pMa0NLU0xxQSJ9.wiwySYm6fXZre-3IdT1tb_02KMQDrMICwUawVf7Gjhc.k84s7ne8J41QnA5BQ31k_A.kjIveRjjNYV4x92CVE9Agw.uAygkyeO2KWeFQIy9JLU0A
The class is agnostic of the payload that is encrypted. Any value may be encrypted. KeyId may be set to include an identifier to help the receiving party identify the key or certificate used to encrypt the data. The following properties are applicable when calling this method:
- EncryptionAlgorithm (required)
- Key (conditional - required for AES)
- KeyPassword (conditional - required for PBES)
- Certificate (conditional - required for ECDH and RSA)
- ContentEncryptionAlgorithm
- CompressionAlgorithm
- Header*
- 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:
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 AES Algorithms (A128KW, A192KW, A256KW, A128GCMKW, A192GCMKW, A256GCMKW)
When EncryptionAlgorithm is set to a AES algorithm Key must be set to a key of appropriate length for the algorithm. For instance a 256 bit key would be used for A256KW.
The example below uses the EzRand class to generate a key, but the key may be created using any method. The key must be known by both parties in order for encryption and decryption to take place.
//Generate a 256 bit (32 byte) key
Ezrand rand = new Ezrand();
rand.RandBytesLength = 32;
rand.GetNextBytes();
byte[] key = rand.RandBytesB;
//Encrypt the payload using A256KW
Jwe jwe = new Jwe();
jwe.KeyB = key;
jwe.InputMessage = "test data";
jwe.EncryptionAlgorithm = JweEncryptionAlgorithms.eaA256KW;
jwe.Encrypt();
string encryptedData = jwe.OutputMessage;
To use an existing AES key provide the bytes to the Key property. For instance:
byte[] key = new byte[] { 164, 60, 194, 0, 161, 189, 41, 38, 130, 89, 141, 164, 45, 170, 159, 209, 69, 137, 243, 216, 191, 131, 47, 250, 32, 107, 231, 117, 37, 158, 225, 234 };
//Encrypt the payload using A256KW
Jwe jwe = new Jwe();
jwe.KeyB = key;
jwe.InputMessage = "test data";
jwe.EncryptionAlgorithm = JweEncryptionAlgorithms.eaA256KW;
jwe.Encrypt();
string encryptedData = jwe.OutputMessage;
Notes for RSA Algorithms (RSA1_5, RSA-OEAP, RSA-OAEP-256)
The RSA based algorithms use asymmetric encryption. Encrypting is done with a public key and decryption is done with a private key. The public certificate should be in PEM (base64) format. For instance:
Jwe jwe = new Jwe();
jwe.Certificate = new Certificate("..\\recipient.cer");
jwe.InputMessage = "test data";
jwe.EncryptionAlgorithm = JweEncryptionAlgorithms.eaRSA_OAEP;
jwe.Encrypt();
string encryptedData = jwe.OutputMessage;
Notes for ECDH Algorithms (ECDH-ES, ECDH-ES+A128KW, ECDH-ES+A192KW, ECDH-ES+A256KW)
ECDH algorithms require a valid ECC public key to encrypt 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 component:
-----BEGIN PUBLIC KEY----- MIIBMjCB7AYHKoZIzj0CATCB4AIBATAsBgcqhkjOPQEBAiEA/////wAAAAEAAAAAAAAAAAAA AAD///////////////8wRAQg/////wAAAAEAAAAAAAAAAAAAAAD///////////////wEIFrG NdiqOpPns+u9VXaYhrxlHQawzFOw9jvOPD4n0mBLBEEEaxfR8uEsQkf4vOblY6RA8ncDfYEt 6zOg9KE5RdiYwpZP40Li/hp/m47n60p8D54WK84zV2sxXs7LtkBoN79R9QIhAP////8AAAAA //////////+85vqtpxeehPO5ysL8YyVRAgEBA0EEIC5rbLp11Mnz6cBXLLriaDIov3rm8RAY x/OR0bOKiff0cQy+sLVaxjseqFk/+Xvl4ORSv5Z6HdHv5GyEpA0UoA== -----END PUBLIC KEY-----
Jwe jwe = new Jwe();
jwe.Certificate = new Certificate(CertStoreTypes.cstPublicKeyFile, pubKeyFile, "", "*");
jwe.InputMessage = "test data";
jwe.EncryptionAlgorithm = JweEncryptionAlgorithms.eaECDH_ES_A256KW;
jwe.Encrypt();
string encryptedData = jwe.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 properties of the ECC component first to obtain the PEM formatted public key. For instance:
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 ecc = new Ecc();
ecc.Key.RxB = x_bytes;
ecc.Key.RyB = y_bytes;
string pubKey = ecc.Key.PublicKey;
Jwe jwe = new Jwe();
jwe.Certificate = new Certificate(CertStoreTypes.cstPublicKeyFile, pubKey, "", "*");
jwe.InputMessage = "test data";
jwe.EncryptionAlgorithm = JweEncryptionAlgorithms.eaECDH_ES_A256KW;
jwe.Encrypt();
string encryptedData = jwe.OutputMessage;
Notes for PBES Algorithms (PBES2-HS256+A128KW, PBES2-HS384+A192KW, PBES2-HS512+A256KW
PBES algorithms derive a content encryption key from the KeyPassword property. Set KeyPassword to a shared secret.
Jwe jwe = new Jwe();
jwe.KeyPassword = "secret";
jwe.InputMessage = "test data";
jwe.EncryptionAlgorithm = JweEncryptionAlgorithms.eaPBES2_HS512_A256KW;
jwe.Encrypt();
string encryptedData = jwe.OutputMessage;
Notes for Direct Shared Keys
When EncryptionAlgorithm is set to Direct the Key property must be set to a valid symmetric key that will be used directly by the ContentEncryptionAlgorithm. In this case a content encryption key is not generated randomly, the Key is used instead. The length of the specified Key must be valid for the selected ContentEncryptionAlgorithm. For instance:
//Generate a 256 bit (32 byte) key
Ezrand rand = new Ezrand();
rand.RandBytesLength = 32;
rand.GetNextBytes();
byte[] key = rand.RandBytesB;
Jwe jwe = new Jwe();
jwe.EncryptionAlgorithm = JweEncryptionAlgorithms.eaDir;
jwe.ContentEncryptionAlgorithm = JweContentEncryptionAlgorithms.ceaA256GCM;
jwe.KeyB = key;
jwe.InputMessage = "test data";
jwe.Encrypt();
string encryptedData = jwe.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.)
Parse Method (JWE Class)
Parses the compact serialized JWE string.
Syntax
ANSI (Cross Platform) int Parse(); Unicode (Windows) INT Parse();
int ipworksencrypt_jwe_parse(void* lpObj);
int Parse();
Remarks
This method parses, but does not decrypt, the JWE string.
Take care when using this method as no decryption is performed. This method may be helpful in cases where only header information is desired.
If decryption is desired, use Decrypt instead. It is not necessary to call this method before calling Decrypt. Decrypt will both parse and decrypt the message.
When calling this method the headers are parsed. The HeaderParam and RecipientInfo events will fire and the HeaderParam* properties will be populated.
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 (JWE Class)
Resets the class.
Syntax
ANSI (Cross Platform) int Reset(); Unicode (Windows) INT Reset();
int ipworksencrypt_jwe_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 (JWE Class)
Sets the stream from which the class will read data.
Syntax
ANSI (Cross Platform) int SetInputStream(IPWorksEncryptStream* sInputStream); Unicode (Windows) INT SetInputStream(IPWorksEncryptStream* sInputStream);
int ipworksencrypt_jwe_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.
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.)
SetOutputStream Method (JWE Class)
Sets the stream to which the class will write data.

Input and Output Properties
The class will determine the source and destination of the input and output based on which properties are set.
The order in which the input properties are checked is as follows:
When a valid source is found the search stops. The order in which the output properties are checked is as follows:
- 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.)
Error Event (JWE Class)
Fired when information is available about errors during data delivery.
Syntax
ANSI (Cross Platform) virtual int FireError(JWEErrorEventParams *e);
typedef struct {
int ErrorCode;
const char *Description; int reserved; } JWEErrorEventParams;
Unicode (Windows) virtual INT FireError(JWEErrorEventParams *e);
typedef struct {
INT ErrorCode;
LPCWSTR Description; INT reserved; } JWEErrorEventParams;
#define EID_JWE_ERROR 1 virtual INT IPWORKSENCRYPT_CALL FireError(INT &iErrorCode, LPSTR &lpszDescription);
class JWEErrorEventParams { public: int ErrorCode(); const QString &Description(); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void Error(JWEErrorEventParams *e);
// Or, subclass JWE and override this emitter function. virtual int FireError(JWEErrorEventParams *e) {...}
Remarks
The Error event is fired in case of exceptional conditions during message processing. Normally the class 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 section.
HeaderParam Event (JWE Class)
Fires once for each JOSE header parameter.
Syntax
ANSI (Cross Platform) virtual int FireHeaderParam(JWEHeaderParamEventParams *e);
typedef struct {
const char *Name;
const char *Value;
int DataType; int reserved; } JWEHeaderParamEventParams;
Unicode (Windows) virtual INT FireHeaderParam(JWEHeaderParamEventParams *e);
typedef struct {
LPCWSTR Name;
LPCWSTR Value;
INT DataType; INT reserved; } JWEHeaderParamEventParams;
#define EID_JWE_HEADERPARAM 2 virtual INT IPWORKSENCRYPT_CALL FireHeaderParam(LPSTR &lpszName, LPSTR &lpszValue, INT &iDataType);
class JWEHeaderParamEventParams { public: const QString &Name(); const QString &Value(); int DataType(); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void HeaderParam(JWEHeaderParamEventParams *e);
// Or, subclass JWE and override this emitter function. virtual int FireHeaderParam(JWEHeaderParamEventParams *e) {...}
Remarks
When Decrypt or Parse 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)
RecipientInfo Event (JWE Class)
Fired with information about the recipient key of the encrypted message.
Syntax
ANSI (Cross Platform) virtual int FireRecipientInfo(JWERecipientInfoEventParams *e);
typedef struct {
const char *KeyId;
const char *Algorithm; int reserved; } JWERecipientInfoEventParams;
Unicode (Windows) virtual INT FireRecipientInfo(JWERecipientInfoEventParams *e);
typedef struct {
LPCWSTR KeyId;
LPCWSTR Algorithm; INT reserved; } JWERecipientInfoEventParams;
#define EID_JWE_RECIPIENTINFO 3 virtual INT IPWORKSENCRYPT_CALL FireRecipientInfo(LPSTR &lpszKeyId, LPSTR &lpszAlgorithm);
class JWERecipientInfoEventParams { public: const QString &KeyId(); const QString &Algorithm(); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void RecipientInfo(JWERecipientInfoEventParams *e);
// Or, subclass JWE and override this emitter function. virtual int FireRecipientInfo(JWERecipientInfoEventParams *e) {...}
Remarks
This event fires with information about the key used to encrypt the data. This may be used to help identify the Key or Certificate to load in order to decrypt the message. This event fires when Decrypt or Parse is called.
KeyId is the Id of the key as supplied by the entity that created the message. This may be empty.
Algorithm is the encryption algorithm used to encrypt the data.
IPWorksEncryptStream Type
Syntax
IPWorksEncryptStream (declared in ipworksencrypt.h)
Remarks
The JWE class includes one or more API members that take a stream object as a parameter. To use such API members, create a concrete class that implements the IPWorksEncryptStream interface and pass the JWE class an instance of that concrete class.
When implementing the IPWorksEncryptStream interface's properties and methods, they must behave as described below. If the concrete class's implementation does not behave as expected, undefined behavior may occur.
Config Settings (JWE Class)
The class accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.JWE Config Settings
This setting specifies the compression algorithm to use (if any). If set the content will be compressed using the specified algorithm. Possible values are:
- 0 (none - default)
- 1 (deflate)
This setting may optionally be set when Algorithm is set to an ECDH algorithm before calling Encrypt. When calling Decrypt this setting is populated and also accessible from within the RecipientInfo event. The value may be any string. To specify a base64url encoded value directly prefix the string with [b64]. For instance the following lines both set the same value:
jwe.Config("PartyUInfo=Alice");
jwe.Config("PartyUInfo=[b64]QWxpY2U="); //Equivalent to above line
This setting may optionally be set when Algorithm is set to an ECDH algorithm before calling Encrypt. When calling Decrypt this setting is populated and also accessible from within the RecipientInfo event. The value may be any string. To specify a base64url encoded value directly prefix the string with [b64]. For instance the following lines both set the same value:
jwe.Config("PartyUInfo=Bob");
jwe.Config("PartyUInfo=[b64]Qm9i"); //Equivalent to above line
This setting specifies the PBDKF2 iteration count. A minimum value of 1000 is recommended. The default value is 1000.
This setting is only applicable when EncryptionAlgorithm is set to a PBES algorithm.
This setting specifies the length in bytes of the salt input value, which is used as part of the PBKDF2 salt value. The default value is 16.
This setting is only applicable when EncryptionAlgorithm is set to a PBES algorithm.
This setting may be queried after calling Encrypt or Decrypt to obtain the raw JOSE header. This returns a JSON string like:
{"alg":"A128GCMKW","enc":"A256CBC-HS512","iv":"oSqGqGiA48O1uD9b","tag":"0WNBx27Z5aL5uvsd01d1Tw"}
If set to True the class will validate the that algorithms used in the JWE message match the values specified in EncryptionAlgorithm and ContentEncryptionAlgorithm. If either algorithms do not match the class fails with an error.
By default this setting is False and the algorithms are read automatically from the encrypted JWE message.
Base Config Settings
When queried, this setting will return a string containing information about the product's build.
The default code page is Unicode UTF-8 (65001).

When queried, this setting will return a string containing information about the license this instance of a class is using. 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.
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.
This setting only works on these classes: AS3Receiver, AS3Sender, Atom, Client(3DS), FTP, FTPServer, IMAP, OFTPClient, SSHClient, SCP, Server(3DS), Sexec, SFTP, SFTPServer, SSHServer, TCPClient, TCPServer.
If set to False, the class will not fire internal idle events. Set this to False to use the class in a background thread on Mac OS. By default, this setting is True.
If there are no events to process when DoEvents is called, the class will wait for the amount of time specified here before returning. The default value is 20.
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.
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 section.
Trappable Errors (JWE Class)
Error Handling (C++)
Call the GetLastErrorCode() method to obtain the last called method's result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. Known error codes are listed below. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.
