Summary

The app uses sha-256 as the hash for passwords. The app should switch to bcrypt.

Details

SHA-256 is a message digest hash, and not classified as secure for password hashing. Message digest hashes are designed to be fast, while password hashing mechanisms are designed with certain cryptographic properties (e.g. slow) to protect against vulnerabilities.
