Passwords are stored in clear text or with an encryption algorithm Updating passwords in database with Argon2idįirst of all, it is important to remember that storing passwords in clear, readable text is forbidden in certain countries such as France. Moreover, we will provide PHP code as an example, but the algorithms can be applied to other languages. As a reminder, the pepper is identical for all users. In case you want to add a pepper, just hash the pepper + password. Passwords are stored with an unsuitable hash (md5, sha1, sha2, sha3…).Passwords are stored in clear text or with an encryption algorithm.To do this, we will start from 2 common cases: In the following, we will show how to update passwords with Argon2id. Use a pepper to provide additional defense in depth (although on its own it does not provide any additional security features).If FIPS-140 compliance is required, use PBKDF2 with a work factor of 600,000 or more and an internal hash function of HMAC-SHA-256.For older systems using Bcrypt, use a work factor of 10 or more and a password limit of 72 bytes.If Argon2id is not available, use Scrypt with a minimum CPU/memory cost setting of (2^17), a minimum block size of 8 (1024 bytes) and a parallelism setting of 1.Use Argon2id with a minimum configuration of 19 MiB of memory, a number of iterations of 2, and 1 degree of parallelism.However, a problem is regularly noted on already existing applications: how to use the latest recommendations on password storage on an existing database? How to securely store passwords?īefore getting to the heart of the matter, a few details on the OWASP recommendations on password storage: This helps to render brute force or dictionary attacks completely ineffective. In a previous article, we saw why it was important to store passwords in a database with robust hash functions such as Bcrypt and Argon2.
