Functions

recipient_key_purpose_is_acceptable_on_receive

Whether purpose on the recipientKeyIndex key of an inbound, already on-chain contact request is acceptable for the ECDH that unwraps the sender’s encryptedPublicKey.

recipient_key_purpose_is_valid

Whether purpose is acceptable for the recipientKeyIndex key of a contact request we are about to mint. The newest cohort references the recipient’s DECRYPTION key (our original convention); the dominant mobile cohort has no DECRYPTION key and references its ENCRYPTION key. Accept either; reject every other purpose.

sender_key_purpose_is_acceptable_on_receive

Receive-side counterpart of [sender_key_purpose_is_valid]: whether purpose on the senderKeyIndex key of an inbound, already on-chain contact request is acceptable for ECDH.
