/mathematica-12-activation-key-generator.html. I am wondering whether I can use a shared secret key established between two clients as the HMAC key too. I saw that there is a problem when it is used as a CBC-MAC but I haven't found any evidence it is bad practice for HMACs. Thanks, Vladimir.

  • Previously, XCBC requires three keys, (k +2 n) bits in total, and TMAC requires two keys, (k + n) bits in total, where n denotes the block length of E. The saving of the key.
  • I am developing a platform that uses several secret keys for several usages: key1 for hashing passwords (using pbkdf2-hmac-sha256), key2 to generate non-repeating unpredictable uuids (using aes-128 and a counter), etc. Instead of storing different keys, I thought to generate them from a single key, i.e.
  • Understanding CBC-MAC variable-length weakness Title says it all - I've started reading about CBC-MAC when this was posted. So essentially i know what the problem is but im having trouble understanding it (both visually and proving it mathematically).

  • Enc-Mac (AES CTR+CBC) mixing AES-256 and AES-128 and splitting keys. I'm looking to accomplish a Enc-then-Mac approach using AES-CTR and ECBC-MAC Now ECBC-MAC requires 2 distinct keys, one for the MAC, and one to encrypt the Tag.
