Connect to the production environment.
Start using the internet acquiring service.
The process of creating a new user security session involves several sequential steps, such as:
Generating client keys - "Process of generating client communication JWK keys".
Obtaining encrypted authorization data by encrypting the request body - "Process of creating JWE encrypted data" and sending the "Request to create a technical session".
Decrypting the received data.

Only for assistance during testing! They are prohibited from being executed with production keys.
Example of encrypt/decrypt
def encrypt_data(self, msg: str, use_server_public_key: bool = False) -> str:
"""Get compact JWE token with encrypted data"""
if not use_server_public_key:
with open(self.public_key, 'rb') as public_key_file:
public_key_raw = json.loads(public_key_file.read().decode())
public_key = jwk.JWK()
key_raw = self.server_public_key if use_server_public_key else public_key_raw
public_key.import_key(**key_raw)
protected_header = {'alg': 'ECDH-ES+A256KW', 'enc': 'A256GCM'}
jwetoken = jwe.JWE(msg.encode('utf-8'), recipient=public_key, protected=protected_header)
return jwetoken.serialize(compact=True)
def decrypt_data(self, msg: str) -> str:
"""Get decrypted data (from JWE)"""
with open(self.private_key, 'rb') as private_key_file:
private_key_raw = json.loads(private_key_file.read().decode())
private_key = jwk.JWK()
private_key.import_key(**private_key_raw)
jwetoken = jwe.JWE()
jwetoken.deserialize(msg, key=private_key)
return jwetoken.payload.decode()
Process of Generating Client Communication JWK Keys
Generating a public and private key (JSON Web Key) is done with the following parameters:
