SHA-256 Generator
Free online SHA-256 hash generator.
What Is a SHA-256 Generator?
The SHA-256 Generator calculates a highly secure 256-bit (32-byte) hash value, represented as a 64-character hexadecimal string. SHA-256 is part of the SHA-2 family of cryptographic algorithms designed by the NSA. It is currently one of the most widely used and secure hashing algorithms in the world.

Frequently Asked Questions
No. SHA-256 is a cryptographic one-way function. It is mathematically impossible to reverse-engineer the original text from the hash alone.
SHA-256 is the industry standard for password hashing, SSL/TLS certificates, digital signatures, and is famously the algorithm used in Bitcoin's proof-of-work system.
As of now, SHA-256 is considered highly secure and there are no known practical collision attacks against it.
