Frequently Asked Questions

1. Which hash algorithm should I use?

SHA-256 is a strong general-purpose choice for most modern use cases. MD5 and SHA-1 are faster but considered cryptographically weak and shouldn't be used for security-sensitive purposes.

2. Can I reverse a hash back into the original text?

No, hashing is a one-way function by design — you cannot recover the original input from the hash output.

3. Is my text sent anywhere or stored?

No, hashing happens per request and nothing you enter is stored afterward.
