Hashing a secret key with a random string to generate a new key
Lets say Alice and Bob have a secret key k1. This key is 50 chars long and is cryptographically random. Alice generates a cryptographically random string (e.g. 16 chars long) and hashes this string and k1 with an algorithm like pbkfd2 or s… Continue reading Hashing a secret key with a random string to generate a new key
