mdn_options Property

Used to indicate the options requested for the MDN receipt.

Syntax

def get_mdn_options() -> str: ...
def set_mdn_options(value: str) -> None: ...

mdn_options = property(get_mdn_options, set_mdn_options)

Default Value

"signed-receipt-protocol=optional, pkcs7-signature; signed-receipt-micalg=optional, sha-256"

Remarks

By default, the class will request that the MDN be signed with a PKCS#7 signature over a SHA-256 hash, which is the industry standard.

Set mdn_options to an empty string to request an unsigned receipt.

This property will automatically be updated when signature_algorithm is set. Normally you will not need to set this property, however you can set a value here to override the automatically generated value.

The string format is that of the Disposition-Notification-Options HTTP header, as specified in RFC 3335. As a form of shorthand, you may set this property to "sha1", "sha-256", or "md5" to request the indicated hash algorithm.
