CSP Hash Generator

Generate a hash for an inline <script> or <style> block, to include in your Content Security Policy.

Code to hash

ℹ The hash is computed byte by byte. A single extra space or newline invalidates it.

Coverage

  • SHA-256 / 384 / 512 — the three CSP algos
  • byte-exact — hash on the exact bytes entered
  • type auto — JS / CSS / unknown heuristic
  • script-src / style-src — ready-to-paste directives
  • quote auto — CSP value pre-quoted
  • full header — full Content-Security-Policy line
