key_algorithm Property

This property holds the algorithm associated with the key.

Syntax

def get_key_algorithm() -> int: ...
def set_key_algorithm(value: int) -> None: ...

key_algorithm = property(get_key_algorithm, set_key_algorithm)

Default Value

0

Remarks

This property holds the algorithm associated with the key. Possible values are:

• 0 (eaSecp256r1)
• 1 (eaSecp384r1)
• 2 (eaSecp521r1)
• 3 (eaEd25519)
• 4 (eaEd448)
• 5 (eaX25519)
• 6 (eaX448)
• 7 (eaSecp160k1)
• 8 (eaSecp192k1)
• 9 (eaSecp224k1)
• 10 (eaSecp256k1)

When assigning a key using the PEM formatted key_private_key and key_public_key the key_algorithm property will be automatically updated with the key algorithm.

When assigning a key using the raw key parameters (keyk, key_rx, and key_ry for NIST or key_x_pk, and key_x_sk for Curve25519/Curve448) the key_algorithm property must be set manually to the key algorithm.
