🧠 What is SHA-256?

SHA-256 stands for Secure Hash Algorithm 256-bit. It belongs to the SHA-2 family and produces a 64-character hexadecimal hash value. It's a cryptographic hash function that ensures the integrity and security of data.

The SHA-256 algorithm is deterministic—meaning it always gives the same output for the same input—and irreversible, which makes it ideal for cryptographic use cases like authentication, API security, and blockchain technology.

💬 Frequently Asked Questions

Q: Can I decrypt a SHA-256 hash?
No. SHA-256 is a one-way hash function. It cannot be decrypted or reversed.

Q: Is SHA-256 secure?
Yes. It's considered secure and is used by governments, banks, and blockchains around the world.

Q: What's the difference between SHA-256 and SHA-512?
SHA-256 creates a 256-bit hash, while SHA-512 creates a 512-bit hash. SHA-512 offers more security but is slightly heavier in computation.
