Common Hashing Mistakes
Hashing is simple to use and easy to misuse. These are the errors that matter most.
Hashing passwords naively
A bare SHA-256 of a password is fast to brute-force and identical for identical passwords. Password storage needs a slow, salted algorithm like bcrypt or Argon2.
Trusting weak algorithms
MD5 and SHA-1 are broken for security. Using them to verify authenticity gives a false sense of safety. Choose SHA-256 or stronger when an attacker could be involved.
Frequently asked questions
Can I use this for production work?
