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:

• SigningAlgorithm (required)
• Certificate (conditional - required for ECDSA and RSA)
• Key (conditional - required for HMAC)
• ClaimAudience
• ClaimExp
• ClaimIssuedAt
• ClaimIssuer
• ClaimJWTId
• ClaimNotBefore
• HeaderParams
• KeyId

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 Certificate property 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 HeaderParams property will contain the headers. Headers of the parsed message are also available through the HeaderParam event.

The following properties are applicable when calling this method:

• EncodedJWT (required)
• Key (conditional - required for HMAC)
• SignerCert (conditional - required for ECDSA and RSA)
• SigningAlgorithm (only if StrictValidation is True)
• StrictValidation
• ExpectedAudience (optional)
• ExpectedExp (optional)
• ExpectedIssuedAt (optional)
• ExpectedIssuer (optional)
• ExpectedJWTId (optional)
• ExpectedNotBefore (optional)
• ExpectedSubject (optional)

After calling this method the following properties are populated:

• ClaimAudience
• ClaimExp
• ClaimIssuedAt
• ClaimIssuer
• ClaimJWTId
• ClaimNotBefore
• ClaimSubject
• HeaderParams

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 Certificate property. An example PEM encoded public certificate created by the CertMgr class:

-----BEGIN CERTIFICATE-----
MIIBETCBtaADAgECAgF7MAwGCCqGSM49BAMCBQAwEDEOMAwGA1UEAxMFZWNkc2EwHhcNMjMw
NzAzMTcwMjU3WhcNMjQwNzAyMTcwMjU3WjAQMQ4wDAYDVQQDEwVlY2RzYTBZMBMGByqGSM49

/0xnxxxIpQ==
-----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 Certificate 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:

• EncryptionAlgorithm (required)
• Key (conditional - required for AES)
• KeyPassword (conditional - required for PBES)
• RecipientCert (conditional - required for ECDH and RSA)
• ClaimAudience
• ClaimExp
• ClaimIssuedAt
• ClaimIssuer
• ClaimJWTId
• ClaimNotBefore
• CompressionAlgorithm
• ContentEncryptionAlgorithm
• HeaderParams
• KeyId

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 Certificate property. An example PEM encoded public certificate created by the ECC component:

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

-----END 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:

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 HeaderParams property will contain the headers. Headers of the parsed message are also available through the HeaderParam event.

The following properties are applicable when calling this method:

• Certificate (conditional - required for RSA and ECDH)
• EncodedJWT
• Key (conditional - required for AES)
• ContentEncryptionAlgorithm (only if StrictValidation is True)
• EncryptionAlgorithm (only if StrictValidation is True)
• HeaderParams
• StrictValidation

After calling this method the following properties are populated:

• ClaimAudience
• ClaimExp
• ClaimIssuedAt
• ClaimIssuer
• ClaimJWTId
• ClaimNotBefore
• ClaimSubject
• HeaderParams

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 Certificate property.

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

Sizes (in bytes)

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).

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:

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:

Config Method (IPWorksAuth_JWT Class)

Sets or retrieves a configuration setting.

Object Oriented Interface

public function doConfig($configurationstring);

Procedural Interface

ipworksauth_jwt_do_config($res, $configurationstring);

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.

Decrypt Method (IPWorksAuth_JWT Class)

Decrypts the encoded JWT.

Object Oriented Interface

public function doDecrypt();

Procedural Interface

ipworksauth_jwt_do_decrypt($res);

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:

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 HeaderParams property will contain the headers. Headers of the parsed message are also available through the HeaderParam event.

The following properties are applicable when calling this method:

• Certificate (conditional - required for RSA and ECDH)
• EncodedJWT
• Key (conditional - required for AES)
• ContentEncryptionAlgorithm (only if StrictValidation is True)
• EncryptionAlgorithm (only if StrictValidation is True)
• HeaderParams
• StrictValidation

After calling this method the following properties are populated:

• ClaimAudience
• ClaimExp
• ClaimIssuedAt
• ClaimIssuer
• ClaimJWTId
• ClaimNotBefore
• ClaimSubject
• HeaderParams

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 Certificate property.

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;

Encrypt Method (IPWorksAuth_JWT Class)

Encrypts the claims with the specified algorithms.

Object Oriented Interface

public function doEncrypt();

Procedural Interface

ipworksauth_jwt_do_encrypt($res);

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:

• EncryptionAlgorithm (required)
• Key (conditional - required for AES)
• KeyPassword (conditional - required for PBES)
• RecipientCert (conditional - required for ECDH and RSA)
• ClaimAudience
• ClaimExp
• ClaimIssuedAt
• ClaimIssuer
• ClaimJWTId
• ClaimNotBefore
• CompressionAlgorithm
• ContentEncryptionAlgorithm
• HeaderParams
• KeyId

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 Certificate property. 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;

Parse Method (IPWorksAuth_JWT Class)

Parses the encoded JWT.

Object Oriented Interface

public function doParse();

Procedural Interface

ipworksauth_jwt_do_parse($res);

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 HeaderParams property will be populated.

If the message is signed (not encrypted) the claims will also be parsed and the Claim* properties will be populated.

Reset Method (IPWorksAuth_JWT Class)

Resets the class properties.

Object Oriented Interface

public function doReset();

Procedural Interface

ipworksauth_jwt_do_reset($res);

Remarks

This method resets all message and key properties to their default values.

Sign Method (IPWorksAuth_JWT Class)

Signs the payload with the specified algorithm.

Object Oriented Interface

public function doSign();

Procedural Interface

ipworksauth_jwt_do_sign($res);

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:

• SigningAlgorithm (required)
• Certificate (conditional - required for ECDSA and RSA)
• Key (conditional - required for HMAC)
• ClaimAudience
• ClaimExp
• ClaimIssuedAt
• ClaimIssuer
• ClaimJWTId
• ClaimNotBefore
• HeaderParams
• KeyId

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 Certificate property 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;

Verify Method (IPWorksAuth_JWT Class)

Verifies the signature of the encoded JWT.

Object Oriented Interface

public function doVerify();

Procedural Interface

ipworksauth_jwt_do_verify($res);

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 HeaderParams property will contain the headers. Headers of the parsed message are also available through the HeaderParam event.

The following properties are applicable when calling this method:

• EncodedJWT (required)
• Key (conditional - required for HMAC)
• SignerCert (conditional - required for ECDSA and RSA)
• SigningAlgorithm (only if StrictValidation is True)
• StrictValidation
• ExpectedAudience (optional)
• ExpectedExp (optional)
• ExpectedIssuedAt (optional)
• ExpectedIssuer (optional)
• ExpectedJWTId (optional)
• ExpectedNotBefore (optional)
• ExpectedSubject (optional)

After calling this method the following properties are populated:

• ClaimAudience
• ClaimExp
• ClaimIssuedAt
• ClaimIssuer
• ClaimJWTId
• ClaimNotBefore
• ClaimSubject
• HeaderParams

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 Certificate property. An example PEM encoded public certificate created by the CertMgr class:

-----BEGIN 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 Certificate properties.

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

ClaimInfo Event (IPWorksAuth_JWT Class)

Fires once for each claim.

Object Oriented Interface

public function fireClaimInfo($param);

Procedural Interface

ipworksauth_jwt_register_callback($res, 1, array($this, 'fireClaimInfo'));

Parameter List

 'name'
 'value'
 'datatype'

Remarks

When Decrypt, Verify or Parse is called this event will fire once for each claim in the JWT.

Name is the name of the claim.

Value is the value of the claim.

DataType specifies the JSON data type of the value. Possible values are:

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

Error Event (IPWorksAuth_JWT Class)

Fired when information is available about errors during data delivery.

Object Oriented Interface

public function fireError($param);

Procedural Interface

ipworksauth_jwt_register_callback($res, 2, array($this, 'fireError'));

Parameter List

 'errorcode'
 'description'

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 (IPWorksAuth_JWT Class)

Fires once for each JOSE header parameter.

Object Oriented Interface

public function fireHeaderParam($param);

Procedural Interface

ipworksauth_jwt_register_callback($res, 3, array($this, 'fireHeaderParam'));

Parameter List

 'name'
 'value'
 'datatype'

Remarks

When Decrypt, Verify 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 (IPWorksAuth_JWT Class)

Fired with information about the recipient key of the encrypted message.

Object Oriented Interface

public function fireRecipientInfo($param);

Procedural Interface

ipworksauth_jwt_register_callback($res, 4, array($this, 'fireRecipientInfo'));

Parameter List

 'keyid'
 'algorithm'

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 properties 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.

SignerInfo Event (IPWorksAuth_JWT Class)

Fires with information about the signature.

Object Oriented Interface

public function fireSignerInfo($param);

Procedural Interface

ipworksauth_jwt_register_callback($res, 5, array($this, 'fireSignerInfo'));

Parameter List

 'keyid'
 'algorithm'

Remarks

This event fires with information about the signature. This may be used to help identify the Key or Certificate properties to load in order to verify the signature. This event fires when Verify or Parse is called.

KeyId is the Id of the key as supplied by the signer that created the message. This may be empty.

Algorithm is the signature algorithm used to sign the message.
