Password hashing security of argon2 versus bcrypt/PBKDF2?

Splet11. okt. 2014 · So that implies that PBKDF2+sha1 is about 1000 times weaker than bcrypt at equivalent cost settings. Note though that PBDFK2+sha512 is almost as slow as bcrypt. This has to do with SHA-512 using 64 bit operations (which aren't native in today's GPUs). … SpletAnother difference between PBKDF2 and scrypt is that PBKDF2 is a generic construction for turning any cryptographic hash function (actually, a pseudorandom function, but the most common way to obtain a PRF for PBKDF2 is to build one out of a hash function using the … do ugly foods taste worse taste test

Splet31. jan. 2024 · There are already password hashing algorithms other than the cryptographic hashes like the SHAx series. Some important are Scrypt (2009), PBKDF2 (2000), Argon2 (2015), and Balloon Hashing (2016). Argon2 was the winner of the password hashing competition held in 2015. Now, Balloon Hashing can fight with Argon2. SpletThe short answer is that SCRYPT has additional protections against brute forcing AND uses PBKDF2.
