WebHMAC is demonstrably resistant (to 128-bit level) even if an adversary can obtain the MAC of chosen messages, under weak hypothesis for SHA-256 (see M. Bellare: New Proofs for NMAC and HMAC: Security without Collision-Resistance, also in proceedings of Crypto 2006 ); therefore, the predictability of UUID+Time is a non-issue. WebThe HMAC might be founded on message-digest calculations along with the SHA256, MD5 etc. Ownership of an HMAC esteem does now not bargain the delicate realities as HMACs aren't reversible curios.
