WebArgon2 is simply a costlier algorithm to brute force. Argon2i uses data-independent memory access. It is slower because it makes more passes over the memory to protect from trade off attacks. It is highly recommended for password hashing and password-based key derivation. Bcrypt is still an acceptable hash for passwords. WebTheoretically, a brute-force mode is possible by testing all the binary strings, but a short message of 6 bytes already represents 281,000 billion combinations.Even with fast processors capable of performing millions of hash calculations per second, several days, months or years of calculations are therefore necessary to try all the possibilities in order … physiotherapie achim reiner
