About SHA-256
SHA-256 is a cryptographic hash function that produces a 256-bit hash value from input data.
It's the industry standard for secure hashing, used in Bitcoin, SSL certificates, and digital signatures.
SHA-256 hashes are deterministic and collision-resistant, making them ideal for data integrity verification.
Use SHA-256 for file checksums, data integrity checks, and compatibility with systems that use SHA-256.
Security Information
Compare SHA-256 hashes to check file contents against a reference value.
Generate a SHA-256 hash from text or a file and compare it with a reference hash. Use the 64-character hexadecimal result to check downloads, backups, and data transfers.
