SHA-256 Hash Generator for Secure Checksums

Generate SHA-256 hashes for integrity checks and security workflows.

SHA-256 Hash Generator

Generate SHA-256 hashes for secure integrity checks and cryptographic workflows. This is commonly used for verifying files, messages, and identifiers.

How to use the SHA-256 Hash Generator

  1. Paste your text or value.
  2. Click Generate.
  3. Copy the SHA-256 hash output.

Common use cases

  • Verifying file integrity in releases.
  • Generating hashes for signatures.
  • Comparing content across environments.
  • Creating stable identifiers from content.

Tips & notes

  • SHA-256 output is always 64 hex characters.
  • Identical input always produces identical output.
  • Use a salt and slow hash for password storage.

Safety note

SHA-256 is a general-purpose hash, not a password storage algorithm. For passwords, use bcrypt, Argon2, or PBKDF2 with a unique salt.

FAQ

Is SHA-256 encryption?
No. SHA-256 is a one-way hash function and cannot be reversed.
Is SHA-256 secure for passwords?
SHA-256 is strong, but for passwords use a slow hash with salt like bcrypt or Argon2.
Do you store my input or hash?
No. All hashing is done instantly and nothing is saved.
Does the same input always generate the same hash?
Yes. SHA-256 is deterministic, so identical input always produces the same hash.
Can SHA-256 be used for file integrity?
Yes. It is commonly used for integrity checks.
