  • Generating digital signatures for API authentication.
  • Creating irreversible tokens for session management.

Frequently Asked Questions

Can a hash be reversed to find the original text?

No, cryptographic hashes are designed to be one-way functions. They cannot be decrypted.

Which algorithm is the most secure?

Currently, SHA-256 and SHA-512 are considered highly secure for most applications. MD5 and SHA-1 are deprecated for cryptographic use.

Is my text sent to a server?

No, all hashing is performed locally in your browser using the Web Crypto API.

Why does a small change in text change the entire hash?

This is known as the 'avalanche effect,' a crucial property of cryptographic hashes to prevent attackers from predicting the input.

Can I hash files with this tool?

This specific tool is optimized for text, but you can paste the text content of files to generate their hash.
