CryptoKeyManager Class

Properties   Methods   Events   Config Settings   Errors  

The CryptoKeyManager class provides a simple way to load, generate and manage generic crypto keys.

Syntax

class secureblackbox.CryptoKeyManager

Remarks

CryptoKeyManager allows you to load, save, generate, import, and export low-level crypto keys. One example of such keys are raw RSA keys stored in PKCS1 format or AES256 keys. CryptoKeyManager supports asymmetric, symmetric, and HMAC keys.

CryptoKeyManager is a typical companion for low-level cryptography classes, such as PublicKeyCrypto, SymmetricCrypto, and HashFunction. It can also be used to provide external key material to certificate objects, and to derive cryptographic keys from passwords.

Use import_bytes or import_from_file method to load the key material from a buffer or file. Use import_from_cert (and remember to assign the certificate object to the certificate property before calling it) to import a key from an X.509 certificate. Once loaded, the key will be available in the key property.

To generate a new key or keypair use generate method. You can export the generated key using export_bytes or export_to_file method. You can attach the generated or loaded key to an external certificate object using the export_to_cert method.

Note: CryptoKeyManager can only work with one cryptographic key at a time. Use CryptoKeyStorage to access media containing more than one key.

def set_key_handle(value: int) -> None: ...

key_handle = property(get_key_handle, set_key_handle)

Default Value

0

Remarks

Allows to get or set a 'handle', a unique identifier of the underlying property object. Use this property to assign objects of the same type in a quicker manner, without copying them fieldwise.

When you pass a handle of one object to another, the source object is copied to the destination rather than assigned. It is safe to get rid of the original object after such operation. pdfSigner.setSigningCertHandle(certMgr.getCertHandle());

key_id Property

Provides access to a storage-specific key identifier.

Syntax

def get_key_id() -> bytes: ...
def set_key_id(value: bytes) -> None: ...

key_id = property(get_key_id, set_key_id)

Remarks

Provides access to a storage-specific key identifier. Key identifiers are used by cryptographic providers to refer to a particular key and/or distinguish between different keys. They are typically unique within a storage, but there is no guarantee that a particular cryptoprovider will conform to that (or will assign any key IDs at all).

key_iv Property

The initialization vector (IV) of a symmetric key.

Syntax

def get_key_iv() -> bytes: ...
def set_key_iv(value: bytes) -> None: ...

key_iv = property(get_key_iv, set_key_iv)

key_key Property

The byte array representation of the key.

Syntax

def get_key_key() -> bytes: ...

key_key = property(get_key_key, None)

Remarks

The byte array representation of the key. This may not be available for non-key_exportable keys.

This property is read-only.

key_nonce Property

A nonce value associated with a key.

Syntax

def get_key_nonce() -> bytes: ...
def set_key_nonce(value: bytes) -> None: ...

key_nonce = property(get_key_nonce, set_key_nonce)

Remarks

A nonce value associated with a key. It is similar to IV, but its only purpose is to introduce randomness.

key_private Property

Returns True if the object hosts a private key, and False otherwise.

Syntax

def get_key_private() -> bool: ...

key_private = property(get_key_private, None)

Default Value

FALSE

Remarks

Returns True if the object hosts a private key, and False otherwise.

Syntax

def get_key_symmetric() -> bool: ...

key_symmetric = property(get_key_symmetric, None)

Default Value

FALSE

Remarks

Returns True if the object contains a symmetric key, and False otherwise.

This property is read-only.

key_valid Property

Returns True if this key is valid.

Syntax

def get_key_valid() -> bool: ...

key_valid = property(get_key_valid, None)

Default Value

FALSE

Remarks

Returns True if this key is valid. The term Valid highly depends on the kind of the key being stored. A symmetric key is considered valid if its length fits the algorithm being set. The validity of an RSA key also ensures that the RSA key elements (primes, exponents, and modulus) are consistent.

This property is read-only.

config Method

Sets or retrieves a configuration setting.

Syntax

def config(configuration_string: str) -> str: ...

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.

derive_key Method

Generates a strong cryptographic key from a password.

Syntax

def derive_key(key_bits: int, password: str, salt: str) -> None: ...

Remarks

Use this method to generate a cryptographically strong key of a needed length from a password.

This method uses a general-purpose PBKDF2 function with PRF1 and 2048 iterations.

do_action Method

Performs an additional action.

Syntax

def do_action(action_id: str, action_params: str) -> str: ...

Remarks

do_action is a generic method available in every class. It is used to perform an additional action introduced after the product major release. The list of actions is not fixed, and may be flexibly extended over time.

The unique identifier (case insensitive) of the action is provided in the ActionID parameter.

ActionParams contains the value of a single parameter, or a list of multiple parameters for the action in the form of PARAM1=VALUE1;PARAM2=VALUE2;....

export_bytes Method

Exports the key to a byte array.

Syntax
