🔐 What is a Hash?

A cryptographic hash is a fixed-length string generated from input data using a mathematical algorithm. The same input always produces the same hash, but even a tiny change in input produces a completely different hash. Hashes are one-way – you cannot reverse them to get the original data.

Common uses include verifying file integrity, storing passwords securely, and generating digital signatures.

⚡ MD5 vs SHA-256

• MD5 – Fast, 128-bit hash. Widely used for checksums but considered cryptographically broken for security-sensitive uses.
• SHA-256 – More secure 256-bit hash from the SHA-2 family. Recommended for passwords, digital signatures, and security applications.

❓ FAQs

Q: Is this tool safe to use with sensitive data?
Yes – all hashing is done locally in your browser. No text is sent to any external server.

Q: Can I reverse a hash to get the original text?
No – hashing is a one-way process by design. You cannot mathematically reverse a hash to recover the original input.
