Frequently Asked Questions
No. Cryptographic hash functions are one-way mathematical algorithms designed so that it is computationally infeasible to invert or reconstruct the original input from the hash value.
For security, cryptography, and password hashing, **SHA-256** and **SHA-512** are strongly recommended. MD5 and SHA-1 are legacy algorithms primarily used for fast non-cryptographic checksum verification.
No. Files Craft processes your file bytes directly inside your local browser memory using the Web Crypto API.
