Question 1

How do I generate a SHA-256 hash online?

Accepted Answer

Type or paste your text into the Hash Generator input field. SHA-256, SHA-1, SHA-512, and MD5 hashes are computed instantly using the browser's native Web Crypto API — no server required.

Question 2

What is the difference between MD5, SHA-1, SHA-256, and SHA-512?

Accepted Answer

These are cryptographic hash functions that produce fixed-length digests. MD5 produces a 128-bit hash, SHA-1 a 160-bit hash, SHA-256 a 256-bit hash, and SHA-512 a 512-bit hash. Longer outputs provide stronger collision resistance.

Question 3

Is MD5 still secure for password hashing?

Accepted Answer

No. MD5 is considered cryptographically broken and should not be used for passwords or security-sensitive applications. Use bcrypt or Argon2 for passwords, and SHA-256 or SHA-512 for data integrity checks.

Question 4

Does this tool upload my text to generate the hash?

Accepted Answer

No data is ever uploaded. All hashing is performed locally in your browser using the Web Crypto API, which is built into every modern browser. Your input remains completely private on your device.
