FAQ

Frequently Asked Questions

A cryptographic hash algorithm converts input data of arbitrary size into a unique, fixed-size string of characters. It is a one-way mathematical function designed so that it is practically impossible to invert or recreate the original input from the hash value.

Yes, by far. MD5 is vulnerable to hash collisions and is no longer recommended for secure password storage or digital signatures. SHA-256 is the modern cryptographic standard used by Bitcoin, SSL/TLS certificates, and enterprise security architectures.

No. Hashing is fundamentally different from encryption. Encryption is a two-way process requiring a key to decrypt back into plaintext. Hashing is strictly a one-way mathematical function; you cannot "decrypt" a hash back to its original string.

Never. All cryptographic computations are performed locally in your browser using the native browser W3C Web Cryptography API (`crypto.subtle`). No strings are ever transmitted to any external server.
