external_crypto_key_id Property

The ID of the pre-shared key used for DC request authentication.

Syntax

def get_external_crypto_key_id() -> str: ...
def set_external_crypto_key_id(value: str) -> None: ...

external_crypto_key_id = property(get_external_crypto_key_id, set_external_crypto_key_id)

Default Value

Remarks

The ID of the pre-shared key used for DC request authentication.

Asynchronous DCAuth-driven communication requires that parties authenticate each other with a secret pre-shared cryptographic key. This provides an extra protection layer for the protocol and diminishes the risk of the private key becoming abused by foreign parties. Use this property to provide the pre-shared key identifier, and use external_crypto_key_secret to pass the key itself.

The same KeyID/KeySecret pair should be used on the DCAuth side for the signing requests to be accepted.

Note: The KeyID/KeySecret scheme is very similar to the AuthKey scheme used in various Cloud service providers to authenticate users.

Example: signer.ExternalCrypto.KeyID = "MainSigningKey"; signer.ExternalCrypto.KeySecret = "abcdef0123456789";

external_crypto_key_secret Property

The pre-shared key used for DC request authentication.

Syntax

def get_external_crypto_key_secret() -> str: ...
def set_external_crypto_key_secret(value: str) -> None: ...

external_crypto_key_secret = property(get_external_crypto_key_secret, set_external_crypto_key_secret)

Default Value

Remarks

The pre-shared key used for DC request authentication. This key must be set and match the key used by the DCAuth counterpart for the scheme to work.

Read more about configuring authentication in the external_crypto_key_id topic.

Specifies the asynchronous signing method.

Syntax

def get_external_crypto_method() -> int: ...
def set_external_crypto_method(value: int) -> None: ...

external_crypto_method = property(get_external_crypto_method, set_external_crypto_method)

Default Value

Remarks

Specifies the asynchronous signing method. This is typically defined by the DC server capabilities and setup.

  @property
  def cancel_decryption() -> bool: ...
  @cancel_decryption.setter
  def cancel_decryption(value) -> None: ...

# In class XMLDecryptor:
@property
def on_decryption_info_needed() -> Callable[[XMLDecryptorDecryptionInfoNeededEventParams], None]: ...
@on_decryption_info_needed.setter
def on_decryption_info_needed(event_hook: Callable[[XMLDecryptorDecryptionInfoNeededEventParams], None]) -> None: ...

Remarks

This event is fired when the component needs decryption information (the private key) from the user.

Use encrypt_key, Config["KeyName"] and key_encryption_type properties to identify the encryption type and then set decryption_key or key_decryption_key or key_decryption_certificate properties accordingly.

if CancelDecryption property is set to true value (default value) then decryption would fail if provided key/certificate is invalid. Otherwise this event would be fired again.

on_error Event

Information about errors during signing.

Syntax

class XMLDecryptorErrorEventParams(object):
  @property
  def error_code() -> int: ...

  @property
  def description() -> str: ...

  def encrypted_data() -> str: ...

  @property
  def data() -> str: ...
  @data.setter
  def data(value) -> None: ...

# In class XMLDecryptor:
@property
def on_external_decrypt() -> Callable[[XMLDecryptorExternalDecryptEventParams], None]: ...
@on_external_decrypt.setter
def on_external_decrypt(event_hook: Callable[[XMLDecryptorExternalDecryptEventParams], None]) -> None: ...

Remarks

Assign a handler to this event if you need to delegate a low-level decryption operation to an external, remote, or custom decryption engine. The handler receives an encrypted value in the EncryptedData parameter, and is expected to decrypt it and place the decrypted value into the Data parameter.

OperationId provides a comment about the operation and its origin. It depends on the exact class being used, and may be empty. Algorithm specifies the encryption algorithm being used, and Pars contains algorithm-dependent parameters.

The class uses base16 (hex) encoding for the EncryptedData, Data, and Pars parameters. If your decryption engine uses a different input and output encoding, you may need to decode and/or encode the data before and/or after the decryption.

Sample data encoded in base16: a0dee2a0382afbb09120ffa7ccd8a152 - lower case base16 A0DEE2A0382AFBB09120FFA7CCD8A152 - upper case base16

Syntax

class XMLDecryptorSaveExternalDataEventParams(object):
  @property
  def external_data() -> bytes: ...

# In class XMLDecryptor:
@property
def on_save_external_data() -> Callable[[XMLDecryptorSaveExternalDataEventParams], None]: ...
@on_save_external_data.setter
def on_save_external_data(event_hook: Callable[[XMLDecryptorSaveExternalDataEventParams], None]) -> None: ...

Remarks

This event is fired when the component successfully decrypted an external data and needs to save it. The same data could be read using external_data property.

It makes sense to use this event when the XML document contains several xenc:EncryptedData elements and the component decrypts them all.
