Developer utility

Hash Generator

Generate SHA-256, SHA-384, or SHA-512 digests locally with the browser Web Crypto API. This is not a password-hashing tool.

Practical guide

Using the Hash Generator

Create SHA-256, SHA-384, or SHA-512 digests.

Example

Input

Text: hello
Algorithm: SHA-256

Expected result

2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824

Supported inputs

  • Text input hashed with SHA-256, SHA-384, or SHA-512 using browser Web Crypto.

Limitations

  • Cryptographic hashes are not encryption and cannot be reversed.
  • Fast SHA hashes are not suitable for password storage; use a dedicated password-hashing algorithm.

Frequently asked questions

Can I decrypt a hash?

No. A hash is a one-way digest; it is used to compare data, not recover the original input.

Should I hash passwords with SHA-256?

No. Password storage should use a password-hashing algorithm such as Argon2id, scrypt, or bcrypt with appropriate parameters.
