WebJun 10, 2024 · Hash-based message authentication code (HMAC) may be used to verify both the data integrity and the authentication of a message. It works like a classic hash algorithm except you need a secret key to generate and validate the hash: HMAC = Hash + Cryptographic key. Only someone with the secret key can generate and validate the hash. WebNov 6, 2024 · HMAC is a cryptographic method that guarantees the integrity of the message between two parties. HMAC algorithm consists of a secret key and a hash function. The secret key is a unique piece of information or a string of characters. It is known both by the sender and the receiver of the message.

WebJun 27, 2024 · If the mnemonic is used purely as BIP39, that is a Bitcoin address is generated directly from the randomly generated used encoded into mnemonic, you need to follow below steps: a) Do n * 11 (where n is the number of mnemonic words). If it is 12, you will get 12 * 11 = 132. b) Calculate the number of seed bits using, 132 = l + l/32, which will ...
