What is the difference between MD5 and SHA-256?

MD5 produces a 128-bit hash and is fast but considered cryptographically weak. SHA-256 is a 256-bit hash from the SHA-2 family, widely used for security-critical applications like SSL certificates and blockchain.

Can I hash files without uploading them?

Yes. Files are read directly in your browser as ArrayBuffers. Nothing is uploaded to any server — hashing is 100% local.

What is Compare Mode?

Compare Mode lets you paste an expected hash value. The tool visually highlights which of the generated hashes matches, making it easy to verify file integrity (e.g., checking downloaded software checksums).

What is a Hash?

A Hash Generator computes cryptographic hash digests (MD5, SHA-1, SHA-256, SHA-512) from text or files. Hashes are one-way fingerprints used to verify data integrity, check file downloads, store passwords securely, and detect tampering. This tool runs entirely in your browser using the WebCrypto API for maximum speed and security.

Why use Birhrt Dev Tools?

Most online developer tools upload your data to a server for processing. This exposes your API keys, personal info, and proprietary code to potential leaks. Birhrt Dev Tools is built differently. Every tool here runs entirely in your browser using modern Web APIs. No server-side processing, no storage, and zero data transmission.
