Frequently Asked Questions
What is a hash?
A hash is a mathematical function that converts an input string of any length into a fixed-length output (the hash digest). It is a one-way process; you cannot convert the hash back to the original text.
Are calculations done on the server?
No. We use the Web Crypto API to calculate SHA-1, SHA-256, and other hashes locally in your browser for maximum privacy and speed.
When should I use SHA-256?
SHA-256 is currently considered secure for most cryptographic purposes, such as verifying file integrity or digital signatures. Avoid SHA-1 or MD5 for sensitive security tasks as they have vulnerabilities.
