Syntax

JWT

Remarks

The JWT class supports signing, encrypting, decrypting and verifying JSON Web Tokens (JWTs).

Specify a set of claims via the Claim* properties or add your own claims with AddClaim. Call Sign to create a signed JWT using a variety of signing algorithms including HMAC, RSA, and ECDSA. Use Verify to verify the signature of any received JWT. See SigningAlgorithm for more details about supported algorithms.

Use Encrypt to create an encrypted JWT using a variety of algorithms including ECDH, RSA, and AES. Use Decrypt to decrypt the payload of any received JWT. See EncryptionAlgorithm 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 SigningAlgorithm to the algorithm which will be used to sign the message. The result of signing is a compact serialized JWT string. For instance:

eyJhbGciOiJIUzI1NiJ9.eyJhdWQiOlsiYXVkaWVuY2UiXSwiaXNzIjoiaXNzdWVyIn0.mlFETSma4WUcUSjNSUWA1n9QBcQHCkHN-y4zeBsCVqI

The class will use the values present in the Claim* properties to build the encoded JWT. After calling this method the EncodedJWT property will hold the compact serialized JWT. The following properties are applicable when calling this method:

Notes for HMAC Algorithms (HS256, HS384, HS512)

When SigningAlgorithm 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 key must be known by both parties in order for signing and verification to take place. 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 Jwt jwt = new Jwt(); jwt.SigningAlgorithm = JwtSigningAlgorithms.saHS256; jwt.ClaimAudience = "audience"; jwt.ClaimIssuer = "issuer"; jwt.ClaimExp = "1498508071"; jwt.KeyB = key; jwt.Sign(); string signedData = jwt.EncodedJWT;

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.

Jwt jwt = new Jwt(); jwt.SigningAlgorithm = JwtSigningAlgorithms.saRS256; jwt.Certificate = new Certificate(CertStoreTypes.cstPFXFile, "..\\jwt.pfx", "test", "*"); jwt.ClaimAudience = "audience"; jwt.ClaimIssuer = "issuer"; jwt.ClaimExp = "1498508071"; jwt.Sign(); string signedMessage = jwt.EncodedJWT;

Notes for ECDSA Algorithms (ES256, ES384, ES512)

ECDSA algorithms require a valid ECC private key in order to sign data. The Cert* properties should be set to a certificate with an ECC key. The CertMgr class can be used to create a certificate with an ECC key.

//Create an ECC key with SHA-256 Certmgr mgr = new Certmgr(); mgr.Config("CertPublicKeyAlgorithm=ECDSA_P256"); mgr.CertStoreType = CertStoreTypes.cstPEMKeyFile; mgr.CertStore = "C:\\temp\\ecdsa.pem"; mgr.CreateCertificate("CN=ecdsa", 123); //Sign the payload using ES256 Jwt jwt = new Jwt(); jwt.SigningAlgorithm = JwtSigningAlgorithms.saES256; jwt.Certificate = new Certificate(CertStoreTypes.cstPEMKeyFile, "C:\\temp\\ecdsa.pem", "", "*"); jwt.ClaimAudience = "audience"; jwt.ClaimIssuer = "issuer"; jwt.ClaimExp = "1498508071"; jwt.Sign(); string signedMessage = jwt.EncodedJWT;

Notes for Unsecured (none)

To create a JWS token without any security set SigningAlgorithm to jwtNone.

Jwt jwt = new Jwt(); jwt.SigningAlgorithm = JwtSigningAlgorithms.saNone; jwt.ClaimAudience = "audience"; jwt.ClaimIssuer = "issuer"; jwt.ClaimExp = "1498508071"; jwt.Sign(); string unsecuredMessage = jwt.EncodedJWT;

Signature Verification

The Verify method may be used to verify a received JWS message. Before calling the Verify method set EncodedJWT to a valid compact serialized JWT. For instance:

eyJhbGciOiJIUzI1NiJ9.eyJhdWQiOlsiYXVkaWVuY2UiXSwiaXNzIjoiaXNzdWVyIn0.mlFETSma4WUcUSjNSUWA1n9QBcQHCkHN-y4zeBsCVqI

The Key or SignerCert* properties should be set to the HMAC key or public certificate respectively. If the correct Key or SignerCert* 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 claims will be parsed and the Claim* properties will be populated. The 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:

After calling this method the following properties are populated:

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 }; Jwt jwt = new Jwt(); jwt.KeyB = key; jwt.EncodedJWT = signedData; jwt.Verify(); string issuer = jwt.ClaimIssuer;

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.

Jwt jwt = new Jwt(); jwt.SignerCert = new Certificate("..\\jwt.cer"); jwt.EncodedJWT = signedData; jwt.Verify(); string issuer = jwt.ClaimIssuer;

Notes for ECDSA Algorithms (ES256, ES384, ES512)

ECDSA algorithms require a valid ECC public key to verify the message. The PEM encoded public key may be used directly with the Cert* properties. An example PEM encoded public certificate created by the CertMgr class:

-----END CERTIFICATE-----

Jwt jwt = new Jwt(); jwt.SignerCert = new Certificate(CertStoreTypes.cstPublicKeyBlob, pubKey, "", "*"); jwt.EncodedJWT = signedData; jwt.Verify(); string issuer = jwt.ClaimIssuer;

Notes for Unsecured (none)

To parse a JWS token without any security call the Sign method without setting the Key or Cert* properties.

Jwt jwt = new Jwt(); jwt.EncodedJWT = signedData; jwt.Verify(); string issuer = jwt.ClaimIssuer;

Encrypting

The Encrypt method may be used to encrypt a payload with a variety of algorithms. To create an encrypted JWT 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 JWT is written to EncodedJWT. For instance:

eyJhbGciOiJBMjU2S1ciLCJlbmMiOiJBMTI4Q0JDLUhTMjU2In0.4tcAnZJ00u4GY2kLOanPOL4CtvcfraZ8SIi6bOZ27qYBI2rHITPc1Q.c_9rCTdPn-saLCti2ZEyWQ.eLwqqo5BGNa70RlsvT-vTh7Gk0hjpJYY_9Zc39Vim_qEtjyMcxZygBpkfx9brzQr9rUbuiAhoCMXKip2-lKT6w.NkuLDPmWxWL4BaTWHWicIQ

The class will use the values present in the Claim* properties to build the encoded JWT. After calling this method the EncodedJWT property will hold the compact serialized JWT. The following properties are applicable when calling this method:

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.

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 Jwt jwt = new Jwt(); jwt.KeyB = key; jwt.ClaimAudience = "audience"; jwt.ClaimIssuer = "issuer"; jwt.ClaimExp = "1498508071"; jwt.EncryptionAlgorithm = JwtEncryptionAlgorithms.eaA256KW; jwt.Encrypt(); string encryptedData = jwt.EncodedJWT;

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:

Jwt jwt = new Jwt(); jwt.Certificate = new Certificate("..\\recipient.cer"); jwt.ClaimAudience = "audience"; jwt.ClaimIssuer = "issuer"; jwt.ClaimExp = "1498508071"; jwt.EncryptionAlgorithm = JwtEncryptionAlgorithms.eaRSA_OAEP; jwt.Encrypt(); string encryptedData = jwt.EncodedJWT;

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 Cert* properties. An example PEM encoded public certificate created by the ECC component:

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

Jwt jwt = new Jwt(); jwt.Certificate = new Certificate(CertStoreTypes.cstPublicKeyFile, pubKeyFile, "", "*"); jwt.ClaimAudience = "audience"; jwt.ClaimIssuer = "issuer"; jwt.ClaimExp = "1498508071"; jwt.EncryptionAlgorithm = JwtEncryptionAlgorithms.eaECDH_ES_A256KW; jwt.Encrypt(); string encryptedData = jwt.EncodedJWT;

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 }; nsoftware.IPWorksEncrypt.Ecc ecc = new nsoftware.IPWorksEncrypt.Ecc(); ecc.Key.RxB = x_bytes; ecc.Key.RyB = y_bytes; string pubKey = ecc.Key.PublicKey; Jwt jwt = new Jwt(); jwt.Certificate = new Certificate(CertStoreTypes.cstPublicKeyFile, pubKey, "", "*"); jwt.ClaimAudience = "audience"; jwt.ClaimIssuer = "issuer"; jwt.ClaimExp = "1498508071"; jwt.EncryptionAlgorithm = JwtEncryptionAlgorithms.eaECDH_ES_A256KW; jwt.Encrypt(); string encryptedData = jwt.EncodedJWT;

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.

Jwt jwt = new Jwt(); jwt.KeyPassword = "secret"; jwt.ClaimAudience = "audience"; jwt.ClaimIssuer = "issuer"; jwt.ClaimExp = "1498508071"; jwt.EncryptionAlgorithm = JwtEncryptionAlgorithms.eaPBES2_HS512_A256KW; jwt.Encrypt(); string encryptedData = jwt.EncodedJWT;

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:

byte[] key = new byte[] { 164, 62, 191, 60, 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 }; Jwt jwt = new Jwt(); jwt.EncryptionAlgorithm = JwtEncryptionAlgorithms.eaDir; jwt.ContentEncryptionAlgorithm = JwtContentEncryptionAlgorithms.ceaA256GCM; jwt.KeyB = key; jwt.ClaimAudience = "audience"; jwt.ClaimIssuer = "issuer"; jwt.ClaimExp = "1498508071"; jwt.Encrypt(); string encryptedData = jwt.EncodedJWT;

Decrypting

The Decrypt method may be used to decrypt a received JWE message. Before calling the Decrypt method set EncodedJWT to a valid compact serialized JWT string. For instance:

eyJhbGciOiJBMjU2S1ciLCJlbmMiOiJBMTI4Q0JDLUhTMjU2In0.4tcAnZJ00u4GY2kLOanPOL4CtvcfraZ8SIi6bOZ27qYBI2rHITPc1Q.c_9rCTdPn-saLCti2ZEyWQ.eLwqqo5BGNa70RlsvT-vTh7Gk0hjpJYY_9Zc39Vim_qEtjyMcxZygBpkfx9brzQr9rUbuiAhoCMXKip2-lKT6w.NkuLDPmWxWL4BaTWHWicIQ

The type and format of the private key depends on the algorithm used to encrypt the data. The following table summarizes the relationship:

AlgorithmPrivate Key Location
AESKey
RSA and ECDHCert*
PBESKeyPassword
If the correct Key or Cert* is not known ahead of time the KeyId parameter of the RecipientInfo event may be used to identify the correct key.

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 Claim* properties 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:

After calling this method the following properties are populated:

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 }; Jwt jwt = new Jwt(); jwt.KeyB = key; jwt.EncodedJWT = encryptedData; jwt.Decrypt(); string issuer = jwt.ClaimIssuer;

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:

Jwt jwt = new Jwt(); jwt.Certificate = new Certificate(CertStoreTypes.cstPFXFile, "..\\jwt.pfx", "password", "*"); jwt.EncodedJWT = encryptedData; jwt.Decrypt(); string issuer = jwt.ClaimIssuer;

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 Cert* properties.

Jwt jwt = new Jwt(); jwt.Certificate = new Certificate(CertStoreTypes.cstPEMKeyFile, privKeyFile, "", "*"); jwt.EncodedJWT = encryptedData; jwt.Decrypt(); string issuer = jwt.ClaimIssuer;

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:

nsoftware.IPWorksEncrypt.Ecc ecc = new nsoftware.IPWorksEncrypt.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; Jwt jwt = new Jwt(); jwt.Certificate = new Certificate(CertStoreTypes.cstPEMKeyBlob, privKey, "", "*"); jwt.EncodedJWT = encryptedData; jwt.Decrypt(); string issuer = jwt.ClaimIssuer;

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.

Jwt jwt = new Jwt(); jwt.KeyPassword = "secret"; jwt.EncodedJWT = encryptedData; jwt.Decrypt(); string issuer = jwt.ClaimIssuer;

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 }; Jwt jwt = new Jwt(); jwt.KeyB = key; jwt.EncodedJWT = encryptedData; jwt.Decrypt(); string issuer = jwt.ClaimIssuer;

Other Functionality

In addition to standard operations 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 JWT without verifying or decrypting by calling Parse

int SetCertEncoded(QByteArray qbaCertEncoded);

Default Value

""

Remarks

This is the certificate (PEM/Base64 encoded). This property is used to assign a specific certificate. The CertStore and CertSubject properties also may be used to specify a certificate.

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

This property is not available at design time.

int ipworksauth_jwt_setcertstore(void* lpObj, const char* lpCertStore, int lenCertStore);
QByteArray GetCertStore();
int SetCertStore(QByteArray qbaCertStore);

Default Value

"MY"

Remarks

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

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

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

Designations of certificate stores are platform dependent.

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

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

When the certificate store type is PFXFile, this property must be set to the name of the file. When the type is PFXBlob, the property must be set to the binary contents of a PFX file (i.e., PKCS#12 certificate store).

Default Value

0

Remarks

This is the type of certificate store for this certificate.

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

0 (cstUser - default)For Windows, this specifies that the certificate store is a certificate store owned by the current user.

Note: This store type is not available in Java.

1 (cstMachine)For Windows, this specifies that the certificate store is a machine store.

Note: This store type is not available in Java.

2 (cstPFXFile)The certificate store is the name of a PFX (PKCS#12) file containing certificates.
3 (cstPFXBlob)The certificate store is a string (binary or Base64-encoded) representing a certificate store in PFX (PKCS#12) format.
4 (cstJKSFile)The certificate store is the name of a Java Key Store (JKS) file containing certificates.

Note: This store type is only available in Java.

5 (cstJKSBlob)The certificate store is a string (binary or Base64-encoded) representing a certificate store in Java Key Store (JKS) format.

Note: this store type is only available in Java.

6 (cstPEMKeyFile)The certificate store is the name of a PEM-encoded file that contains a private key and an optional certificate.
7 (cstPEMKeyBlob)The certificate store is a string (binary or Base64-encoded) that contains a private key and an optional certificate.
8 (cstPublicKeyFile)The certificate store is the name of a file that contains a PEM- or DER-encoded public key certificate.

Note: This store type is only available in Java and .NET.

22 (cstBCFKSBlob)The certificate store is a string (binary or Base64-encoded) representing a certificate store in BCFKS (Bouncy Castle FIPS Key Store) format.

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: certmgr.CertStoreType = CertStoreTypes.cstPKCS11; certmgr.OnCertList += (s, e) => { secKeyBlob = e.CertEncoded; }; certmgr.CertStore = @"C:\Program Files\OpenSC Project\OpenSC\pkcs11\opensc-pkcs11.dll"; certmgr.CertStorePassword = "123456"; //PIN certmgr.ListStoreCertificates(); sftp.SSHCert = new Certificate(CertStoreTypes.cstPKCS11, secKeyBlob, "123456", "*"); sftp.SSHUser = "test"; sftp.SSHLogon("myhost", 22);

99 (cstAuto)The store type is automatically detected from the input data. This setting may be used with both public and private keys and can detect any of the supported formats automatically.

Data Type

String

Key Property (JWT Class)

The key used for HMAC and AES.

Syntax

ANSI (Cross Platform)
int GetKey(char* &lpKey, int &lenKey);
int SetKey(const char* lpKey, int lenKey); Unicode (Windows) INT GetKey(LPSTR &lpKey, INT &lenKey);
INT SetKey(LPCSTR lpKey, INT lenKey);

int ipworksauth_jwt_setkey(void* lpObj, const char* lpKey, int lenKey);
QByteArray GetKey();
int SetKey(QByteArray qbaKey);

Default Value

""

Remarks

This property specifies the key used when signing with an HMAC algorithm or encrypting with an AES algorithm.

Signing

This property is applicable when SigningAlgorithm 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)

SHA1SHA224SHA256SHA384SHA512MD5RIPEMD160
Recommended Key Size20 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 is it first hashed with the same algorithm.

Encrypting

When EncryptionAlgorithm is set to an AES algorithm this property must hold the symmetric key used for encryption and decryption. The size of the key must match the size of the algorithm. For instance when selecting the algorithm A256GCMKW (AES 256) the size of the key must also be 256 bits (32 bytes).

In the case where EncryptionAlgorithm is set to Direct this key is used directly with the algorithm specified by ContentEncryptionAlgorithm and must be an appropriate size for the selected ContentEncryptionAlgorithm.

Data Type

Integer

AddClaim Method (JWT Class)

Adds an new claim.

Syntax

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

Unicode (Windows)
INT AddClaim(LPCWSTR lpszname, LPCWSTR lpszvalue, INT idataType);
int ipworksauth_jwt_addclaim(void* lpObj, const char* lpszname, const char* lpszvalue, int idataType);
int AddClaim(const QString& qsname, const QString& qsvalue, int idataType);

Remarks

This method adds a claim to the existing claims. Use this method to add claims that are not already supported directly via properties.

The Name parameter defines the name of the claim. The Value parameter is the value, represented as a string. The JSON data type of the value is defined by the DataType parameter. Possible DataType values are:

  • 0 (Object)
  • 1 (Array)
  • 2 (String)
  • 3 (Number)
  • 4 (Bool)
  • 5 (Null)

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.)

AddHeaderParam Method (JWT Class)

Adds additional header parameters.

Syntax

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

Unicode (Windows)
INT AddHeaderParam(LPCWSTR lpszname, LPCWSTR lpszvalue, INT idataType);
int ipworksauth_jwt_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 Encrypt or 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)

Signing

To add additional parameters to the JOSE header use this method. For instance to create this header:

{
	"alg": "HS256",
	"crit": [
		"myheader"
	],
	"myheader": "testvalue"
}

The following code can be used:

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 Jwt jwt = new Jwt(); jwt.SigningAlgorithm = JwtSigningAlgorithms.saHS256; jwt.ClaimAudience = "audience"; jwt.ClaimIssuer = "issuer"; jwt.ClaimExp = "1498508071"; jwt.AddHeaderParam("crit", "[\"myheader\"]", 1); jwt.AddHeaderParam("myheader", "testvalue", 2); jwt.KeyB = key; jwt.Sign(); string signedData = jwt.EncodedJWT;

Note: when calling Sign the class will automatically add some headers based on properties that are set.

Parameters Automatically Set:

Header ParamProperty
algAlgorithm
kidKeyId

Encrypting

To add additional parameters to the JOSE header use this method. For instance to create this header:

{
	"alg": "A256GCMKW",
	"enc": "A128CBC-HS256",
	"iv": "cPTXlBL7aMiv-Dnf",
	"tag": "r5tmS-tXmfFngrybpnnt5g",
	"crit": [
		"myheader"
	],
	"myheader": "testvalue"
}

The following code can be used:

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 }; Jwt jwt = new Jwt(); jwt.KeyB = key; jwt.ClaimAudience = "audience"; jwt.ClaimIssuer = "issuer"; jwt.ClaimExp = "1498508071"; jwt.AddHeaderParam("crit", "[\"myheader\"]",1); jwt.AddHeaderParam("myheader", "testvalue",2); jwt.EncryptionAlgorithm = JwtEncryptionAlgorithms.eaA256GCMKW; jwt.Encrypt(); string encryptedData = jwt.EncodedJWT;

Note: When calling Encrypt the class will automatically add headers based on the selected EncryptionAlgorithm and other properties that may be set.

Parameters Automatically Set:

Header ParamProperty
alg EncryptionAlgorithm
enc ContentEncryptionAlgorithm
kid KeyId
zip CompressionAlgorithm
p2c PBES2Count (PBES Algorithms Only)
apu PartyUInfo (ECDH Algorithms Only)
apv PartyVInfo (ECDH Algorithms Only)
iv N/A - Automatically Generated (AES Algorithms Only)
tag N/A - Automatically Generated (AES Algorithms Only)
p2s N/A - Automatically Generated (PBES Algorithms Only)
epk N/A - Automatically Generated (ECDH Algorithms Only)

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 (JWT Class)

Sets or retrieves a configuration setting.

Syntax

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

Unicode (Windows)
LPWSTR Config(LPCWSTR lpszConfigurationString);
char* ipworksauth_jwt_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 (JWT Class)

Decrypts the encoded JWT.

Syntax

ANSI (Cross Platform)
int Decrypt();

Unicode (Windows)
INT Decrypt();
int ipworksauth_jwt_decrypt(void* lpObj);
int Decrypt();

Remarks

This method decrypts the encoded JWT.

Before calling the Decrypt method set EncodedJWT to a valid compact serialized JWT string. For instance:

eyJhbGciOiJBMjU2S1ciLCJlbmMiOiJBMTI4Q0JDLUhTMjU2In0.4tcAnZJ00u4GY2kLOanPOL4CtvcfraZ8SIi6bOZ27qYBI2rHITPc1Q.c_9rCTdPn-saLCti2ZEyWQ.eLwqqo5BGNa70RlsvT-vTh7Gk0hjpJYY_9Zc39Vim_qEtjyMcxZygBpkfx9brzQr9rUbuiAhoCMXKip2-lKT6w.NkuLDPmWxWL4BaTWHWicIQ

The type and format of the private key depends on the algorithm used to encrypt the data. The following table summarizes the relationship:

AlgorithmPrivate Key Location
AESKey
RSA and ECDHCert*
PBESKeyPassword
If the correct Key or Cert* is not known ahead of time the KeyId parameter of the RecipientInfo event may be used to identify the correct key.

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 Claim* properties 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:

After calling this method the following properties are populated:

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 }; Jwt jwt = new Jwt(); jwt.KeyB = key; jwt.EncodedJWT = encryptedData; jwt.Decrypt(); string issuer = jwt.ClaimIssuer;

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:

Jwt jwt = new Jwt(); jwt.Certificate = new Certificate(CertStoreTypes.cstPFXFile, "..\\jwt.pfx", "password", "*"); jwt.EncodedJWT = encryptedData; jwt.Decrypt(); string issuer = jwt.ClaimIssuer;

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 Cert* properties.

Jwt jwt = new Jwt(); jwt.Certificate = new Certificate(CertStoreTypes.cstPEMKeyFile, privKeyFile, "", "*"); jwt.EncodedJWT = encryptedData; jwt.Decrypt(); string issuer = jwt.ClaimIssuer;

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:

nsoftware.IPWorksEncrypt.Ecc ecc = new nsoftware.IPWorksEncrypt.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; Jwt jwt = new Jwt(); jwt.Certificate = new Certificate(CertStoreTypes.cstPEMKeyBlob, privKey, "", "*"); jwt.EncodedJWT = encryptedData; jwt.Decrypt(); string issuer = jwt.ClaimIssuer;

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.

Jwt jwt = new Jwt(); jwt.KeyPassword = "secret"; jwt.EncodedJWT = encryptedData; jwt.Decrypt(); string issuer = jwt.ClaimIssuer;

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 }; Jwt jwt = new Jwt(); jwt.KeyB = key; jwt.EncodedJWT = encryptedData; jwt.Decrypt(); string issuer = jwt.ClaimIssuer;

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 (JWT Class)

Encrypts the claims with the specified algorithms.

Syntax

ANSI (Cross Platform)
int Encrypt();

Unicode (Windows)
INT Encrypt();
int ipworksauth_jwt_encrypt(void* lpObj);
int Encrypt();

Remarks

This method encrypts the claims using the specified algorithms.

To create an encrypted JWT 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 JWT is written to EncodedJWT. For instance:

eyJhbGciOiJBMjU2S1ciLCJlbmMiOiJBMTI4Q0JDLUhTMjU2In0.4tcAnZJ00u4GY2kLOanPOL4CtvcfraZ8SIi6bOZ27qYBI2rHITPc1Q.c_9rCTdPn-saLCti2ZEyWQ.eLwqqo5BGNa70RlsvT-vTh7Gk0hjpJYY_9Zc39Vim_qEtjyMcxZygBpkfx9brzQr9rUbuiAhoCMXKip2-lKT6w.NkuLDPmWxWL4BaTWHWicIQ

The class will use the values present in the Claim* properties to build the encoded JWT. After calling this method the EncodedJWT property will hold the compact serialized JWT. The following properties are applicable when calling this method:

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.

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 Jwt jwt = new Jwt(); jwt.KeyB = key; jwt.ClaimAudience = "audience"; jwt.ClaimIssuer = "issuer"; jwt.ClaimExp = "1498508071"; jwt.EncryptionAlgorithm = JwtEncryptionAlgorithms.eaA256KW; jwt.Encrypt(); string encryptedData = jwt.EncodedJWT;

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:

Jwt jwt = new Jwt(); jwt.Certificate = new Certificate("..\\recipient.cer"); jwt.ClaimAudience = "audience"; jwt.ClaimIssuer = "issuer"; jwt.ClaimExp = "1498508071"; jwt.EncryptionAlgorithm = JwtEncryptionAlgorithms.eaRSA_OAEP; jwt.Encrypt(); string encryptedData = jwt.EncodedJWT;

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 Cert* properties. An example PEM encoded public certificate created by the ECC component:

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 }; nsoftware.IPWorksEncrypt.Ecc ecc = new nsoftware.IPWorksEncrypt.Ecc(); ecc.Key.RxB = x_bytes; ecc.Key.RyB = y_bytes; string pubKey = ecc.Key.PublicKey; Jwt jwt = new Jwt(); jwt.Certificate = new Certificate(CertStoreTypes.cstPublicKeyFile, pubKey, "", "*"); jwt.ClaimAudience = "audience"; jwt.ClaimIssuer = "issuer"; jwt.ClaimExp = "1498508071"; jwt.EncryptionAlgorithm = JwtEncryptionAlgorithms.eaECDH_ES_A256KW; jwt.Encrypt(); string encryptedData = jwt.EncodedJWT;

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.

Jwt jwt = new Jwt(); jwt.KeyPassword = "secret"; jwt.ClaimAudience = "audience"; jwt.ClaimIssuer = "issuer"; jwt.ClaimExp = "1498508071"; jwt.EncryptionAlgorithm = JwtEncryptionAlgorithms.eaPBES2_HS512_A256KW; jwt.Encrypt(); string encryptedData = jwt.EncodedJWT;

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:

byte[] key = new byte[] { 164, 62, 191, 60, 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 }; Jwt jwt = new Jwt(); jwt.EncryptionAlgorithm = JwtEncryptionAlgorithms.eaDir; jwt.ContentEncryptionAlgorithm = JwtContentEncryptionAlgorithms.ceaA256GCM; jwt.KeyB = key; jwt.ClaimAudience = "audience"; jwt.ClaimIssuer = "issuer"; jwt.ClaimExp = "1498508071"; jwt.Encrypt(); string encryptedData = jwt.EncodedJWT;

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 (JWT Class)

Parses the encoded JWT.

Syntax

ANSI (Cross Platform)
int Parse();

Unicode (Windows)
INT Parse();
int ipworksauth_jwt_parse(void* lpObj);
int Parse();

Remarks

This method parses, but does not verify the encoded JWT.

Take care when using this method as no verification or decryption is performed. This method may be helpful in cases where only header information is desired.

If verification or decryption is desired, use Verify or Decrypt instead. It is not necessary to call this method before calling Verify or Decrypt. Verify or 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.

If the message is signed (not encrypted) the claims will also be parsed and the Claim* 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 (JWT Class)

Resets the class properties.

Syntax

ANSI (Cross Platform)
int Reset();

Unicode (Windows)
INT Reset();
int ipworksauth_jwt_reset(void* lpObj);
int Reset();

Remarks

This method resets all message and key 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.)

Sign Method (JWT Class)

Signs the payload with the specified algorithm.

Syntax

ANSI (Cross Platform)
int Sign();

Unicode (Windows)
INT Sign();
int ipworksauth_jwt_sign(void* lpObj);
int Sign();

Remarks

This method signs the claims specified by the Claim* properties with the specified SigningAlgorithm.

Before calling the Sign method set SigningAlgorithm to the algorithm which will be used to sign the message. The result of signing is a compact serialized JWT string. For instance:

eyJhbGciOiJIUzI1NiJ9.eyJhdWQiOlsiYXVkaWVuY2UiXSwiaXNzIjoiaXNzdWVyIn0.mlFETSma4WUcUSjNSUWA1n9QBcQHCkHN-y4zeBsCVqI

The class will use the values present in the Claim* properties to build the encoded JWT. After calling this method the EncodedJWT property will hold the compact serialized JWT. The following properties are applicable when calling this method:

Notes for HMAC Algorithms (HS256, HS384, HS512)

When SigningAlgorithm 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 key must be known by both parties in order for signing and verification to take place. 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 Jwt jwt = new Jwt(); jwt.SigningAlgorithm = JwtSigningAlgorithms.saHS256; jwt.ClaimAudience = "audience"; jwt.ClaimIssuer = "issuer"; jwt.ClaimExp = "1498508071"; jwt.KeyB = key; jwt.Sign(); string signedData = jwt.EncodedJWT;

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.

Jwt jwt = new Jwt(); jwt.SigningAlgorithm = JwtSigningAlgorithms.saRS256; jwt.Certificate = new Certificate(CertStoreTypes.cstPFXFile, "..\\jwt.pfx", "test", "*"); jwt.ClaimAudience = "audience"; jwt.ClaimIssuer = "issuer"; jwt.ClaimExp = "1498508071"; jwt.Sign(); string signedMessage = jwt.EncodedJWT;

Notes for ECDSA Algorithms (ES256, ES384, ES512)

ECDSA algorithms require a valid ECC private key in order to sign data. The Cert* properties should be set to a certificate with an ECC key. The CertMgr class can be used to create a certificate with an ECC key.

//Create an ECC key with SHA-256 Certmgr mgr = new Certmgr(); mgr.Config("CertPublicKeyAlgorithm=ECDSA_P256"); mgr.CertStoreType = CertStoreTypes.cstPEMKeyFile; mgr.CertStore = "C:\\temp\\ecdsa.pem"; mgr.CreateCertificate("CN=ecdsa", 123); //Sign the payload using ES256 Jwt jwt = new Jwt(); jwt.SigningAlgorithm = JwtSigningAlgorithms.saES256; jwt.Certificate = new Certificate(CertStoreTypes.cstPEMKeyFile, "C:\\temp\\ecdsa.pem", "", "*"); jwt.ClaimAudience = "audience"; jwt.ClaimIssuer = "issuer"; jwt.ClaimExp = "1498508071"; jwt.Sign(); string signedMessage = jwt.EncodedJWT;

Notes for Unsecured (none)

To create a JWS token without any security set SigningAlgorithm to jwtNone.

Jwt jwt = new Jwt(); jwt.SigningAlgorithm = JwtSigningAlgorithms.saNone; jwt.ClaimAudience = "audience"; jwt.ClaimIssuer = "issuer"; jwt.ClaimExp = "1498508071"; jwt.Sign(); string unsecuredMessage = jwt.EncodedJWT;

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 (JWT Class)

Verifies the signature of the encoded JWT.

Syntax

ANSI (Cross Platform)
int Verify();

Unicode (Windows)
INT Verify();
int ipworksauth_jwt_verify(void* lpObj);
int Verify();

Remarks

This method verifies the signature of the encoded JWT.

Before calling the Verify method set EncodedJWT to a valid compact serialized JWT. For instance:

eyJhbGciOiJIUzI1NiJ9.eyJhdWQiOlsiYXVkaWVuY2UiXSwiaXNzIjoiaXNzdWVyIn0.mlFETSma4WUcUSjNSUWA1n9QBcQHCkHN-y4zeBsCVqI

The Key or SignerCert* properties should be set to the HMAC key or public certificate respectively. If the correct Key or SignerCert* 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 claims will be parsed and the Claim* properties will be populated. The 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:

After calling this method the following properties are populated:

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 }; Jwt jwt = new Jwt(); jwt.KeyB = key; jwt.EncodedJWT = signedData; jwt.Verify(); string issuer = jwt.ClaimIssuer;

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.

Jwt jwt = new Jwt(); jwt.SignerCert = new Certificate("..\\jwt.cer"); jwt.EncodedJWT = signedData; jwt.Verify(); string issuer = jwt.ClaimIssuer;

Notes for ECDSA Algorithms (ES256, ES384, ES512)

ECDSA algorithms require a valid ECC public key to verify the message. The PEM encoded public key may be used directly with the Cert* properties. An example PEM encoded public certificate created by the CertMgr class:

Config Settings (JWT 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.

JWT 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 is set to true. This allows multiple signing algorithms to be considered acceptable during validation. This setting is only applicable when StrictValidation is set to true. Possible values:

  • HS256
  • HS384
  • HS512
  • RS256
  • RS384
  • RS512
  • ES256
  • ES384
  • ES512
  • PS256
  • PS384
  • PS512

Example value: HS512,HS256.

AudienceDelimiter:   Defines the character to separate audience values.

This setting specifies the character to used to separate multiple audience values. ClaimAudience may contain multiple values. When multiple values are present they will be separated by this character. The default value is ;.

When setting ClaimAudience that contains multiple audiences specify multiple value separated by the character set here. For instance:

jwt.ClaimAudience = "aud1;aud2";

CompressionAlgorithm:   The compression algorithm to use.

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)
ExpectedAudience:   The expected audience claim.

This setting specifies the expected audience claim. When set prior to calling the Verify method, the component will compare the audience claim from the EncodedJWT with this value.

ExpectedExp:   The expected expiration time claim.

This setting specifies the expected expiration time claim. When set prior to calling the Verify method, the component will compare the expitaion time claim from the EncodedJWT with this value.

ExpectedIssuedAt:   The expected time at which the JWT was issued.

This setting specifies the expected issued at claim. When set prior to calling the Verify method, the component will compare the issued at claim from the EncodedJWT with this value.

ExpectedIssuer:   The expected issuer of the JWT.

This setting specifies the expected issuer of the JWT. When set prior to calling the Verify method, the component will compare the issuer of the EncodedJWT with this value.

ExpectedJWTId:   The expected unique identifier for the JWT.

This setting specifies the expected ID of the JWT. When set prior to calling the Verify method, the component will compare the JWT ID of the EncodedJWT with this value.

ExpectedNotBefore:   The expected claim identifying the time before which the JWT is invalid.

This setting specifies the expected not before claim of the JWT. When set prior to calling the Verify method, the component will compare the not before of claim of the EncodedJWT with this value.

ExpectedSubject:   The expected subject indentifying the principal of the JWT.

This setting specifies the expected subject claim of the JWT. When set prior to calling the Verify method, the component will compare the subject claim of the EncodedJWT with this value.

IncludeCertificateFormat:   The certificate values to include in the signed message (if any).

This setting specifies whether information about the Cert* 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 Cert* properties will automatically be included. 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 Cert* set this to 5.

InputMessage:   The raw input to process.

This setting optionally specifies the pay payload to process. When calling Sign or Encrypt input is taken from this setting if specified. If a value is set here the Claim* properties are ignored.

IsEncrypted:   Indicates whether the EncodedJWT is encrypted.

This setting may be queried after calling Parse to determine if the EncodedJWT is encrypted.

IsSigned:   Indicates whether the EncodedJWT is signed.

This setting may be queried after calling Parse to determine if the EncodedJWT is signed.

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 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 Cert* values 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:

-----END CERTIFICATE-----

KeyEncoding:   The encoding of the Key value.

This setting specifies the encoding that has been applied to the Key. value prior to providing it to the class. The Key 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)

OutputMessage:   The raw output of the operation.

After calling Verify or Decrypt this holds the raw JSON payload. This may be useful for debugging or logging purposes when the JSON payload is desired.

PartyUInfo:   Information about the producer of the message.

This setting may optionally be set when EncryptionAlgorithm 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

PartyVInfo:   Information about the recipient of the message.

This setting may optionally be set when EncryptionAlgorithm 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

PBES2Count:   The PBKDF2 iteration count.

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.

PBES2SaltLength:   The salt input value length.

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.

RawHeader:   Holds the raw JOSE header.

This setting may be queried after calling Sign or Verify to obtain the raw JOSE header. This returns a JSON string like:

{"alg":"ES384","kid":"myKeyId"}

StrictValidation:   Requires specific algorithms when processing.

If set to True the class will validate that the algorithm used in the JWT matches the values specified in EncryptionAlgorithm, ContentEncryptionAlgorithm, and SigningAlgorithm. This is applicable when calling Decrypt and Verify.

By default this is False and the algorithms are read automatically from the encoded JWT.

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).

LicenseInfo:   Information about the current license.

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.
MaskSensitive:   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.

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.

ProcessIdleEvents:   Whether the class uses its internal event loop to process events when the main thread is idle.

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.

SelectWaitMillis:   The length of time in milliseconds the class will wait when DoEvents is called if there are no events to process.

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.

UseFIPSCompliantAPI:   Tells the class whether or not to use FIPS certified APIs.

When set to true, the class will utilize the underlying operating system's certified APIs. Java editions, regardless of OS, utilize Bouncy Castle FIPS, while all the other Windows editions make use of Microsoft security libraries.

FIPS mode can be enabled by setting the UseFIPSCompliantAPI configuration setting to true. This is a static setting which applies to all instances of all classes of the toolkit within the process. It is recommended to enable or disable this setting once before the component has been used to establish a connection. Enabling FIPS while an instance of the component is active and connected may result in unexpected behavior.

For more details please see the FIPS 140-2 Compliance article.

Note: This setting is only applicable on Windows.

Note: Enabling FIPS-compliance requires a special license; please contact sales@nsoftware.com for details.

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.

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 (JWT 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.

JWT Errors

301   EncodedJWT is not set. The input is not valid.
302   Failed to parse claims. See error message for details.
303   Claim is not within its validity period.
304   Failed to verify an expected claim value. See error message for details.
