Jeffrey Czyz dd2ccd2322 Stateless verification of InvoiceRequest ... Verify that an InvoiceRequest was produced from an Offer constructed by the recipient using the Offer metadata reflected in the InvoiceRequest. The Offer metadata consists of a 128-bit encrypted nonce and possibly a 256-bit HMAC over the nonce and Offer TLV records (excluding the signing pubkey) using an ExpandedKey. Thus, the HMAC can be reproduced from the offer bytes using the nonce and the original ExpandedKey, and then checked against the metadata. If metadata does not contain an HMAC, then the reproduced HMAC was used to form the signing keys, and thus can be checked against the signing pubkey.		2023-04-19 21:30:40 -05:00
