JWTs are JWS signed objects with a few reserved claims. Args: claims (dict): A claims set to sign key (str or dict): The key to use for signing the claim set. Can be individual JWK or JWK set. algorithm (str, optional): The algorithm to use for signing the the claims. Defaults to HS256. headers (dict, optional): A set of headers that will be added to the default headers. Any headers that are added as additional headers will override the default headers. access_token (str, optional): If present, the 'at_hash' claim will be calculated and added to the claims present in the 'claims' parameter. Returns: str: The string representation of the header, claims, and signature. Raises: JWTError: If there is an error encoding the claims. Examples: >>> jwt.encode({'a': 'b'}, 'secret', algorithm='HS256') 'eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJhIjoiYiJ9.jiMyrsmD8AoHWeQgmxZ5yq8z0lXS67_QGs52AzC8Ru8' )expiatnbfat_hash)headers algorithm) isinstancegetrr utctimetuplerr HASHESrsign)claimskeyrr access_token time_claimr \/var/www/html/construction_image-detection-poc/venv/lib/python3.10/site-packages/jose/jwt.pyencodesr"c Cs8iddddddddddddddd dd dd d d d dd dd dd dd dd dd ddi}|r@|||dd} z tj|||| d} Wntya} zt| d} ~ wwt|d} z t| d} Wnt y} ztd| d} ~ wwt | t stdt | |||| ||d| S)a Verifies a JWT string's signature and validates reserved claims. Args: token (str): A signed JWS to be verified. key (str or dict): A key to attempt to verify the payload with. Can be individual JWK or JWK set. algorithms (str or list): Valid algorithms that should be used to verify the JWS. audience (str): The intended audience of the token. If the "aud" claim is included in the claim set, then the audience must be included and must equal the provided claim. issuer (str or iterable): Acceptable value(s) for the issuer of the token. If the "iss" claim is included in the claim set, then the issuer must be given and the claim in the token must be among the acceptable values. subject (str): The subject of the token. If the "sub" claim is included in the claim set, then the subject must be included and must equal the provided claim. access_token (str): An access token string. If the "at_hash" claim is included in the claim set, then the access_token must be included, and it must match the "at_hash" claim. options (dict): A dictionary of options for skipping validation steps. defaults = { 'verify_signature': True, 'verify_aud': True, 'verify_iat': True, 'verify_exp': True, 'verify_nbf': True, 'verify_iss': True, 'verify_sub': True, 'verify_jti': True, 'verify_at_hash': True, 'require_aud': False, 'require_iat': False, 'require_exp': False, 'require_nbf': False, 'require_iss': False, 'require_sub': False, 'require_jti': False, 'require_at_hash': False, 'leeway': 0, } Returns: dict: The dict representation of the claims set, assuming the signature is valid and all requested data validation passes. Raises: JWTError: If the signature is invalid in any way. ExpiredSignatureError: If the signature has expired. JWTClaimsError: If any claim is invalid in any way.

The "aud" (audience) claim identifies the recipients that the JWT is intended for. Each principal intended to process the JWT MUST identify itself with a value in the audience claim. If the principal processing the claim does not identify itself with a value in the "aud" claim when this claim is present, then the JWT MUST be rejected. In the general case, the "aud" value is an array of case- sensitive strings, each containing a StringOrURI value. In the special case when the JWT has one audience, the "aud" value MAY be a single case-sensitive string containing a StringOrURI value. The interpretation of audience values is generally application specific. Use of this claim is OPTIONAL.

The "sub" (subject) claim identifies the principal that is the subject of the JWT. The claims in a JWT are normally statements about the subject. The subject value MUST either be scoped to be locally unique in the context of the issuer or be globally unique. The processing of this claim is generally application specific.

The "jti" (JWT ID) claim provides a unique identifier for the JWT. The identifier value MUST be assigned in a manner that ensures that there is a negligible probability that the same value will be accidentally assigned to a different data object; if the application uses multiple issuers, collisions MUST be prevented among values produced by different issuers as well. The "jti" claim can be used to prevent the JWT from being replayed. The "jti" value is a case- sensitive string. Use of this claim is OPTIONAL.

Its value is the base64url encoding of the left-most half of the hash of the octets of the ASCII representation of the access_token value, where the hash algorithm used is the hash algorithm used in the alg Header Parameter of the ID Token's JOSE Header. For instance, if the alg is RS256, hash the access_token value with SHA-256, then take the left-most 128 bits and base64url encode them. The at_hash value is a case sensitive string.
