SHA-256 vs MD5: Which Hash Should You Use?

MD5 and SHA-256 both turn input into a fixed-length digest, but they are not interchangeable. Collision resistance and modern security expectations make SHA-256 the default for almost every new integrity use case.

Quick comparison

MD5 produces a 128-bit digest and is fast, but it is cryptographically broken for collision resistance. SHA-256 produces a 256-bit digest and remains widely recommended for integrity hashing.

  • MD5: legacy checksums, non-security fingerprints
  • SHA-256: file integrity, signatures, modern protocols
  • Neither replaces a dedicated password hashing algorithm (Argon2, bcrypt, scrypt)

When MD5 still appears

You may still see MD5 in older CDN cache keys, legacy software checksums, or non-adversarial deduplication. Prefer SHA-256 for anything new that must resist tampering.

Generate hashes locally

Use the Hash Generator to compute MD5, SHA-256, and other digests in your browser — useful for verifying downloads without uploading files.

  1. Open the SHA-256 generator (or the full Hash Generator hub).
  2. Paste text or provide input for hashing.
  3. Compare the digest to the publisher’s published checksum.

Key takeaways

  • Prefer SHA-256 over MD5 for new integrity checks.
  • MD5 is fine only for non-security legacy contexts.
  • Never use raw MD5/SHA for password storage.

Frequently Asked Questions

Is MD5 safe for passwords?

No. Do not use MD5 (or plain SHA-256 alone) for password storage. Use Argon2, bcrypt, or scrypt with unique salts.

Is SHA-256 always better than MD5?

For security-sensitive integrity checks, yes. For purely informational legacy workflows, MD5 may still appear — but migrate when you can.

Can I hash files privately online?

Yes. EazyTools4u hash tools run in the browser so content does not need to be uploaded.
