I think the . GitHub - quexten/clients at feature/argon2-kdf. In this case, we recommend to use a relatively low value for the Argon2 memory parameter (64 MB or less, depending on the app and the database size) and a relatively high number of iterations. The KDF iterations increase the cracking time linearly, so 2,000,000 will take four times as long to crack (on average) than 500,000. The user probably wouldn’t even notice. I have created basic scrypt support for Bitwarden. 2 Likes. json: csp should be "extension page*s*", and add wasm-unsafe-eval so we can load the wasm. ? Have users experienced issues when making this change to an existing Bitwarden account? I know the CYA answer is to always backup the data, which I would do, but I would like to be aware of any potential problems that might arise. With the warning of ### WARNING. log file is updated only after a successful login. Therefore, a rogue server could send a reply for. How about just giving the user the option to pick which one they want to use. Bitwarden has also recently added another KDF option called Argon2id, which defends against GPU-based and side-channel attacks by increasing the memory needed to guess a master password input. wasn’t the whole point of logging me out of all my devices to force me to log back in using the new KDF iterations va. log file is updated only after a successful login. Question: is the encrypted export where you create your own password locked to only. The hash credential to login to Bitwarden servers is only 1 PBKDF2 iteration from the vault master key. Bitwarden Increases KDF iterations to 600k for new accounts and double-encrypts data at rest. The point of argon2 is to make low entropy master passwords hard to crack. Exploring applying this as the minimum KDF to all users. Change the ** KDF iterations** to 600000 (Six Hundred Thousand) or higher! Keep in mind that this doesn't do you much good however if you have a weak master password. Exploring applying this as the minimum KDF to all users. The user probably wouldn’t even notice. If you want to do manual brute-force guesses, go to Bitwarden’s interactive cryptography tool. 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. Not sure if this is already on the @Quexten’s and Bitwarden devs’ list of things to do, but I think it would be very helpful to update the Interactive Cryptography Tool to include an implementation of the new Argon2 KDF Support (including the ability for users to test the settings for iterations, memory, and parallelism parameters). Exploring applying this as the minimum KDF to all users. However, what was more sharply criticized was the failure of LastPass to migrate older accounts to their new default, with many older accounts being left at 5,000 iterations and even reports of accounts with the iterations set to as low as 1. I think the . 6. On a PC or a high end cell phone, you can easily set the iterations well above 1,000,000 and only notice a 1-2 second delay. 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. Anyways, always increase memory first and iterations second as recommended in the argon2. all new threads here are locked, but replies will still function for the time being. Where I agree with the sentiment is when users panicked because they realized that Bitwarden hadn't immediately updated the default KDF iterations from 100k to 310k when OWASP changed their recommendations in 2021, and weren't automatically updating existing users' KDF configurations when the recommendation increased to 600k earlier. Go to “Account settings”. 2 Likes. This means a 13char password with 100,000 iterations is about 2x stronger than a 12char password with 2,000,000 iterations. ” From information found on Keypass that tell me IOS requires low settings. Argon2 KDF Support. Instead of KDF iterations, there is a “Work Factor” which scales linearly with memory and compute. With the ambiguity in some of the Bitwarden staff responses, it is difficult to say at this time what is going on. The point of argon2 is to make low entropy master passwords hard to crack. This was mentioned as BWN-01-009 in Bitwarden’s 2018 Security Assessment, yet there we are five years later. But they don’t even store the kdf / iterations in the database, so changing it would require another database migration / backend change which I didn’t really feel like taking on considering how low the risk for a send is anyways. If you want to avoid feelings of inadequacy when Bitwarden ups the default iterations to 600,000 in a month or two, you can go ahead and increase your KDF iteration value to 600k. If you want to do manual brute-force guesses, go to Bitwarden’s interactive cryptography tool. Vaultwarden works! More data, on the desktop I downgraded the extension for FF to 2022.
