What is a Hash?
A hash is the output of a cryptographic function that converts arbitrary data into a fixed-length string. The same input always produces the same hash, but reversing the process is computationally infeasible.
SHA-256 is an industry-standard hash algorithm used in Bitcoin's blockchain and TLS certificates. It's widely used for file integrity verification, password storage, and digital signatures.

FAQ
What hash algorithms are supported?
SHA-256, SHA-512, and SHA-1 are supported. SHA-256 is the most commonly used for file integrity and security applications.
Is SHA-1 still safe to use?
SHA-1 is considered deprecated for security purposes due to known collision attacks. Use SHA-256 or SHA-512 for security-critical applications. SHA-1 is provided for legacy compatibility.
Can I hash large files?
Yes. The file is processed entirely in your browser using the Web Crypto API. Processing time depends on file size and your device's performance.
