SHA-256 Hash Generator
Generate SHA-256 hash from text input
What is SHA-256?
SHA-256 (Secure Hash Algorithm 256-bit) is a part of the SHA-2 family of cryptographic hash functions, designed by the U.S. National Security Agency (NSA). It is widely used for its strong security properties and is considered to be more secure than its predecessor, SHA-1.
Key Points About SHA-256:
- Produces a 256-bit (32-byte) hash value
- Typically expressed as a 64-digit hexadecimal number
- Widely used in security applications and protocols, including TLS, SSL, PGP, SSH, IPsec, and Bitcoin
- Considered cryptographically secure and resistant to collision attacks
How SHA-256 Hashing Works
SHA-256 hashing involves processing input data to produce a fixed-size output. Here's a brief overview:
- Input is processed in 512-bit blocks
- Sixty-four rounds of operations are performed on each block
- Produces a fixed 256-bit output regardless of input size
- It's a one-way function - you can't reverse the hash to get the original input
This generator allows you to easily create SHA-256 hashes, which are useful for data integrity verification, digital signatures, and secure password storage.
