In the world of cryptography, algorithms play a crucial role in ensuring data security. One such algorithm is HmacPBESHA256, which stands for Hash-based Message Authentication Code Password-Based Encryption SHA-256. However, there are instances where this algorithm may not be available or supported...

In this paper, we propose TLS-HOTP protocol, an extension to TLS to provide client authentication based on pre-shared keys (PSK) using the HMAC-Based One-Time Password (HOTP) algorithm. These pre-shared keys are symmetric keys, but the client's key is stored in a secure token, ensuring...

HMACSHA256 is a type of keyed hash algorithm that is constructed from the SHA-256 hash function and used as a Hash-based Message Authentication Code (HMAC). The HMAC process mixes a secret key with the message data, hashes the result with the hash function, mixes that hash value with th...
