For test cases, an additional third +property is contained, which is the expected output of the verifier. + +Implementers of SD-JWT libraries are advised to run at least the following tests: + + - End-to-end: The issuer creates an SD-JWT according to the input data, the + holder discloses the claims according to the holder disclosed claims, and + the verifier verifies the SD-JWT and outputs the expected verified contents. + The test passes if the output of the verifier matches the expected verified + contents. + - Issuer-direct-to-holder: The issuer creates an SD-JWT according to the input + data and the whole SD-JWT is put directly into the Verifier for consumption. + (Note that this is possible because an SD-JWT presentation differs only by + one '~' character from the SD-JWT issued by the issuer if key binding is + not enforced. This character can easily be added in the test execution.) + This test simulates that a holder releases all data contained in the SD-JWT + and is useful to verify that the Issuer put all data into the SD-JWT in a + correct way. The test passes if the output of the verifier matches the input + user claims (including all claims marked for selective disclosure). + +In this library, the two tests are implemented in +[tests/test_e2e_testcases.py](tests/test_e2e_testcases.py) and +[tests/test_disclose_all_shortcut.py](tests/test_disclose_all_shortcut.py), +respectively. + +The `specification.yml` file has the following format for test cases (find more examples in [tests/testcases](tests/testcases)): + +### Input data: `user_claims` + +`user_claims` is a YAML dictionary with the user claims, i.e., the payload that +is to be turned into an SD-JWT. **Object keys** and **array elements** (and only +those!) can be marked for selective disclosure at any level in the data by +applying the YAML tag "!sd" to them. + +This is an example of an object where two out of three keys are marked for selective disclosure: + +```yaml +user_claims: + is_over: + "13": True # not selectively disclosable - always visible to the verifier + !sd "18": False # selectively disclosable + !sd "21": False # selectively disclosable +``` + +The following shows an array with two elements, where both are marked for selective disclosure: + +```yaml +user_claims: + nationalities: + - !sd "DE" + - !sd "US" +``` + +The following shows an array with two elements that are both objects, one of which is marked for selective disclosure: + +```yaml +user_claims: + addresses: + - street: "123 Main St" + city: "Anytown" + state: "NY" + zip: "12345" + type: "main_address" + + - !sd + street: "456 Main St" + city: "Anytown" + state: "NY" + zip: "12345" + type: "secondary_address" +``` + +The following shows an object that has only one claim (`sd_array`) which is marked for selective disclosure. Note that within the array, there is no selective disclosure. + +```yaml +user_claims: + !sd sd_array: + - 32 + - 23 +``` + +### Holder Behavior: `holder_disclosed_claims` + +`holder_disclosed_claims` is a YAML dictionary with the claims that the holder +discloses to the verifier. The structure must follow the structure of +`user_claims`, but elements can be omitted. The following rules apply: + + - For scalar values (strings, numbers, booleans, null), the value must be + `True` or `yes` if the claim is disclosed and `False` or `no` if the claim + should not be disclosed. + - Arrays mirror the elements of the same array in `user_claims`. For each + value, if it is not `False` or `no`, the value is disclosed. If an array + element in `user_claims` is an object or array, an object or array can be + provided here as well to describe which elements of that object/array should + be disclosed or not, if applicable. + - For objects, list all keys that are to be disclosed, using a value that is + not `False` or `no`. As above, if the value is an object or array, it is used + to describe which elements of that object/array should be disclosed or not, + if applicable. + +### Verifier Output: `expect_verified_user_claims` + +Finally, `expect_verified_user_claims` describes what the verifier is expected +to output after successfully consuming the presentation from the holder. In +other words, after applying `holder_disclosed_claims` to `user_claims`, the +result is `expect_verified_user_claims`. + +### Other Properties + + +When `key_binding` is set to `true`, a Key Binding JWT will be generated. + +Using `serialization_format`, the serialization format of the SD-JWT can be +specified.

It has been adapted to use the [`cryptojwt`](https://github.com/IdentityPython/JWTConnect-Python-CryptoJWT) library as the core JWT implementation. -## Setup +The purpose of this fork is to: +1. Leverage the robustness and extended features provided by the `cryptojwt` library. +2. Maintain compatibility with existing SD-JWT specifications. +3. Provide a more modular and extensible codebase for advanced use cases. -To install this implementation, make sure that `python3` and `pip` (or `pip3`) are available on your system and run the following command: +If you're familiar with the original `sd-jwt-python` library, this fork retains similar functionality with minimal API changes, if needed. -```bash -# create a virtual environment to install the dependencies -python3 -m venv venv -source venv/bin/activate +--- -# install the latest version from git -pip install git+https://github.com/openwallet-foundation-labs/sd-jwt-python.git -``` +## Features -This will install the `sdjwt` python package and the `sd-jwt-generate` script. +- **SD-JWT Support**: Implements the Selective Disclosure JWT standard. +- **`cryptojwt` Integration**: Leverages a mature and feature-rich library for JWT operations. +- **Backward Compatibility**: Minimal changes required for existing users of `sd-jwt-python`. +- **Improved Flexibility**: Extensible for custom SD-JWT use cases. -If you want to access the scripts in a new shell, it is required to activate the virtual environment: - -```bash -source venv/bin/activate -``` - -## sd-jwt-generate - -The script `sd-jwt-generate` is useful for generating test cases, as they might be used for doing interoperability tests with other SD-JWT implementations, and for generating examples in the SD-JWT specification and other documents. - -For both use cases, the script expects a JSON file with settings (`settings.yml`). Examples for these files can be found in the [tests/testcases](tests/testcases) and [examples](examples) directories. - -Furthermore, the script expects, in its working directory, one subdirectory for each test case or example. In each such directory, there must be a file `specification.yml` with the test case or example specifications. Examples for these files can be found in the subdirectories of the [tests/testcases](tests/testcases) and [examples](examples) directories, respectively. - -The script outputs the following files in each test case or example directory: - * `sd_jwt_issuance.txt`: The issued SD-JWT. (*) - * `sd_jwt_presentation.txt`: The presented SD-JWT. (*) - * `disclosures.md`: The disclosures, formatted as markdown (only in 'example' mode). - * `user_claims.json`: The user claims. - * `sd_jwt_payload.json`: The payload of the SD-JWT. - * `sd_jwt_jws_part.txt`: The serialized JWS component of the SD-JWT. (*) - * `kb_jwt_payload.json`: The payload of the key binding JWT. - * `kb_jwt_serialized.txt`: The serialized key binding JWT. - * `verified_contents.json`: The verified contents of the SD-JWT. - -(*) Note: When JWS JSON Serialization is used, the file extensions of these files are `.json` instead of `.txt`. - -To run the script, enter the respective directory and execute `sd-jwt-generate`: - -```bash -cd tests/testcases -sd-jwt-generate example -``` - -## specification.yml for Test Cases and Examples - -The `specification.yml` file contains the test case or example specifications. -For examples, the file contains the 'input user data' (i.e., the payload that is -turned into an SD-JWT) and the holder disclosed claims (i.e., a description of -what data the holder wants to release). For test cases, an additional third -property is contained, which is the expected output of the verifier. - -Implementers of SD-JWT libraries are advised to run at least the following tests: - - - End-to-end: The issuer creates an SD-JWT according to the input data, the - holder discloses the claims according to the holder disclosed claims, and - the verifier verifies the SD-JWT and outputs the expected verified contents. - The test passes if the output of the verifier matches the expected verified - contents. - - Issuer-direct-to-holder: The issuer creates an SD-JWT according to the input - data and the whole SD-JWT is put directly into the Verifier for consumption. - (Note that this is possible because an SD-JWT presentation differs only by - one '~' character from the SD-JWT issued by the issuer if key binding is - not enforced. This character can easily be added in the test execution.) - This test simulates that a holder releases all data contained in the SD-JWT - and is useful to verify that the Issuer put all data into the SD-JWT in a - correct way. The test passes if the output of the verifier matches the input - user claims (including all claims marked for selective disclosure). - -In this library, the two tests are implemented in -[tests/test_e2e_testcases.py](tests/test_e2e_testcases.py) and -[tests/test_disclose_all_shortcut.py](tests/test_disclose_all_shortcut.py), -respectively. - -The `specification.yml` file has the following format for test cases (find more examples in [tests/testcases](tests/testcases)): - -### Input data: `user_claims` - -`user_claims` is a YAML dictionary with the user claims, i.e., the payload that -is to be turned into an SD-JWT. **Object keys** and **array elements** (and only -those!) can be marked for selective disclosure at any level in the data by -applying the YAML tag "!sd" to them. - -This is an example of an object where two out of three keys are marked for selective disclosure: - -```yaml -user_claims: - is_over: - "13": True # not selectively disclosable - always visible to the verifier - !sd "18": False # selectively disclosable - !sd "21": False # selectively disclosable -``` - -The following shows an array with two elements, where both are marked for selective disclosure: - -```yaml -user_claims: - nationalities: - - !sd "DE" - - !sd "US" -``` - -The following shows an array with two elements that are both objects, one of which is marked for selective disclosure: - -```yaml -user_claims: - addresses: - - street: "123 Main St" - city: "Anytown" - state: "NY" - zip: "12345" - type: "main_address" - - - !sd - street: "456 Main St" - city: "Anytown" - state: "NY" - zip: "12345" - type: "secondary_address" -``` - -The following shows an object that has only one claim (`sd_array`) which is marked for selective disclosure. Note that within the array, there is no selective disclosure. - -```yaml -user_claims: - !sd sd_array: - - 32 - - 23 -``` - -### Holder Behavior: `holder_disclosed_claims` - -`holder_disclosed_claims` is a YAML dictionary with the claims that the holder -discloses to the verifier. The structure must follow the structure of -`user_claims`, but elements can be omitted. The following rules apply: - - - For scalar values (strings, numbers, booleans, null), the value must be - `True` or `yes` if the claim is disclosed and `False` or `no` if the claim - should not be disclosed. - - Arrays mirror the elements of the same array in `user_claims`. For each - value, if it is not `False` or `no`, the value is disclosed. If an array - element in `user_claims` is an object or array, an object or array can be - provided here as well to describe which elements of that object/array should - be disclosed or not, if applicable. - - For objects, list all keys that are to be disclosed, using a value that is - not `False` or `no`. As above, if the value is an object or array, it is used - to describe which elements of that object/array should be disclosed or not, - if applicable. - -### Verifier Output: `expect_verified_user_claims` - -Finally, `expect_verified_user_claims` describes what the verifier is expected -to output after successfully consuming the presentation from the holder. In -other words, after applying `holder_disclosed_claims` to `user_claims`, the -result is `expect_verified_user_claims`. - -### Other Properties - - -When `key_binding` is set to `true`, a Key Binding JWT will be generated. - -Using `serialization_format`, the serialization format of the SD-JWT can be -specified.
