Hi, as in for the same reason as in Scrypt KDF Support , I decided to add Argon2 support. My understanding is that a strong master password should still be secure even with a low number of KDF iterations, but for a product like a password manager, the bar should probably be higher than that. By the way, Sends (which I don’t really use) also have 100K fixed pbkdf2. 12. log file is updated only after a successful login. 2 Likes. The hash credential to login to Bitwarden servers is only 1 PBKDF2 iteration from the vault master key. Security Now podcast did a follow-up to the last episode on the LastPass debacle and one of the things that Steve Gibson mentioned is that vault providers need to move away from PBKDF2 and the number of hash iterations to an algorithm that is resistant to GPU attacks. The point of argon2 is to make low entropy master passwords hard to crack. The user probably wouldn’t even notice. I don’t think this replaces an automatic migration or at least global notifications for iterations set below the default, but it is still a good suggestion. And low enough where the recommended value of 8ms should likely be raised. OK fine. Exploring applying this as the minimum KDF to all users. There's no "fewer iterations if the password is shorter" recommendation. LastPass uses the standard PBKDF2 (Password-Based Key Derivation Function 2). rs I noticed the default client KDF iterations is 5000:. With the warning of ### WARNING. ## Code changes - manifestv3.

We recommend that you. all new threads here are locked, but replies will still function for the time being. On mobile, I just looked for the C# argon2 implementation with the most stars. By the way, Sends (which I don’t really use) also have 100K fixed pbkdf2. I had never heard of increasing only in increments of 50k until this thread. Instead of KDF iterations, there is a “Work Factor” which scales linearly with memory and compute. We recommend a value of 100,000 or more. log file is updated only after a successful login. When using one of the Desktop apps, the entire encrypted vault (except for attachments) is stored in a file named data. Our default is 100,000 iterations, the Min allows for higher performance at the user's discretion but the key length combined with the password still makes this. You should switch to Argon2. The slowness of the Argon2id algorithm can also be adjusted by increasing the number of iterations required, but Argon2id also provides for other adjustments that can make it. Hi, as in for the same reason as in Scrypt KDF Support , I decided to add Argon2 support. On the cli, argon2 bindings are. This operation logs the user out of all accounts in any event so it should be relatively low friction to update the KDF iterations simultaneously. I just set it to 2000000 (2 million) which is the max that bitwarden currently allows (Dec 27th 2022) login times: pixel 6 : ~5 seconds lenovo Thinkpad P1 gen 3 (manufactured/assembled 11/16/2020) with Intel(R) Core(TM) i7-10875H 8/16 HT core : ~5 secondsThe server limits the max kdf iterations (even for the current kdf) to an insecure/low value. The PBKDF2 algorithm can (in principle) be made slower by requiring that the calculation be repeated (by specifying a large number of KDF “iterations”). If your keyHash. Exploring applying this as the minimum KDF to all users. On the typescript-based platforms, argon2-browser with WASM is used. 6. none of that will help in the type of attack that led to the most recent lastpass breach. According to comments posted by Quexten at Bitwarden's community forums, the company has a 5-week release cycle, so we could expect Argon2 support to be added next month on all platforms if the tests are successful. Click on the box, and change the value to 600000. If the KDF iteration count is set too high, some devices may fail to complete the PBKDF2-HMAC-SHA256 calculation because of insufficient computing power — this is more likely to occur on mobile devices and older hardware. Setting your KDF iterations too high could result in poor performance when logging into (and unlocking) Bitwarden on slower or older devices. At our organization, we are set to use 100,000 KDF iterations. In contrast, Dmitry Chestnykh wrote a well-researched piece in 2020 (with an update in January 2023) that describes exactly how a brute-force attack against a stolen Bitwarden vault would be possible using only 100,000 PBKDF2 iterations (or the KDF iteration value set by the user) per password guess, and even proposed an improved authentication. This operation logs the user out of all accounts in any event so it should be relatively low friction to update the KDF iterations simultaneously. iOS limits app memory for autofill. Any idea when this will go live?. If your keyHash value is from later than June 9, 2021, you will need to save a copy of the HTML code of this webpage. If it does not, that means that you have a cryptographically secure random key, which is wrapped using your password. By default, the iteration count in the client is 5,000 but supports up to 2,000,000. For scrypt there are audited, and fuzzed libraries such as noble-hashes. Palant said this flaw meant that the security level of Bitwarden is identical to what LastPass had. This operation logs the user out of all accounts in any event so it should be relatively low friction to update the KDF iterations simultaneously.
