Security & Integrity
Hash Generator
Compute SHA-based hash digests for text directly in your browser using the Web Crypto API. Helpful for quick integrity checks and debugging.
Privacy note: Hashes are computed locally in your browser via the Web Crypto API.
Input text and digests are not intended to be sent to NovaTools Hub servers. As always, avoid pasting
highly sensitive secrets or long-lived credentials into any online tool.

Algorithm overview
| Algorithm | Digest length | Typical usage | Notes |
|---|---|---|---|
| SHA-256 | 256 bits / 64 hex chars | Checksums, content addressing, HMACs | Good general-purpose choice for integrity checks. |
| SHA-512 | 512 bits / 128 hex chars | High-assurance checksums, large datasets | Stronger but larger digest than SHA-256. |
| SHA-384 | 384 bits / 96 hex chars | Some TLS/PKI configurations | Less commonly used but supported in Web Crypto. |
| SHA-1 | 160 bits / 40 hex chars | Legacy systems only | Considered cryptographically weak; avoid for new designs. |
These hashes are not salted or stretched and are not suitable on their own for password storage. Production systems should use dedicated password hashing algorithms such as bcrypt, scrypt, PBKDF2, or Argon2 with appropriate configuration.
