Frequently Asked Questions

What is SHA-256?
SHA-256 is a cryptographic hash function producing a 64-character hexadecimal string, part of the SHA-2 family.
Is SHA-256 secure?
Yes. SHA-256 is currently considered cryptographically secure — used in Bitcoin, TLS/SSL, and authentication systems.
Is my text sent to a server?
No. SHA-256 hashing is computed entirely in your browser using the Web Crypto API.
What is SHA-256 used for?
Password hashing (with salting), digital signatures, file integrity verification, blockchain, and TLS certificates.
Can I reverse a SHA-256 hash?
No. SHA-256 is a one-way function — mathematically impossible to reverse.

💡 Always salt passwords

Never hash passwords with SHA-256 alone — always add a unique salt and use bcrypt or Argon2.

💡 File verification

Verify downloaded files by comparing their SHA-256 checksum with the one published by the software provider.

💡 Case consistency

SHA-256 hashes are case-insensitive but use lowercase consistently for reliable string comparisons.

💡 Deterministic output

The same input always produces the same SHA-256 hash — useful for detecting changes in file content.

SHA-256 is the modern standard for cryptographic hashing in security applications, file verification, and blockchain technology.
