Frequently Asked Questions
A hash is a fixed-length output generated from any input using a mathematical algorithm. The same input always produces the same hash. It is one-way — you cannot reverse it to get the original text.
SHA-256 is widely used in blockchain, digital signatures, and secure password hashing (with salt). It is currently considered cryptographically secure.
No. SHA-256 is a one-way function. You cannot reverse it mathematically. The only way to crack it is by brute-force or rainbow tables, which is computationally infeasible for strong inputs.
