The recommended minimums for Argon2, as per OWASP Cheat Sheet Series (https://cheatsheetseries.owasp.org/cheatsheets/Password_Storage_Cheat_Sheet.html), are: Use Argon2id with a minimum configuration of 15 MiB of memory, an iteration count of 2, and 1 degree of parallelism. Previous default configuration: memory=4, iterations=3, parallelism=1 New default configuration: memory=16, iterations=2, parallelism=1 Issue spring-projectsgh-10506
The recommended minimums for scrypt, as per OWASP Cheat Sheet Series (https://cheatsheetseries.owasp.org/cheatsheets/Password_Storage_Cheat_Sheet.html), are: Use scrypt with a minimum CPU/memory cost parameter of (2^16), a minimum block size of 8 (1024 bytes), and a parallelization parameter of 1. Previous default configuration: cpuCost=16384, memoryCost=8, parallelism=1 New default configuration: cpuCost=65536, memoryCost=8, parallelism=1 The default salt length was also updated from 64 to 16.

The recommended minimums for PBKDF2, as per OWASP Cheat Sheet Series (https://cheatsheetseries.owasp.org/cheatsheets/Password_Storage_Cheat_Sheet.html), are: If FIPS-140 compliance is required, use PBKDF2 with a work factor of 310,000 or more and set with an internal hash function of HMAC-SHA-256. Previous default configuration: algorithm=SHA1, iterations=185000, hashLength=256 New default configuration: algorithm=SHA256, iterations=310000, hashLength=256 The default salt length was also updated from 8 to 16.
