The hash credential to login to Bitwarden servers is only 1 PBKDF2 iteration from the vault master key. Therefore, a rogue server could send a reply for any number of client iterations and get a result that always is 1 PBKDF2 away from the master key. philco tubesSplet22. apr. 2014 · Yes. It isn't relying on custom code for the security of the password hash. Its only the utilization of .NET PBKDF2 library for hashing the password, and using the proper IV and Salt - along with the iteration count and being able to change that iteration count in the future without interrupting existing accounts. philco tt8w1i
