Which cryptographic hash algorithms are provided?

This tool generates MD5, SHA-1, SHA-256, and SHA-512 hashes in real-time as you type.

Which hash algorithm should I use for passwords?

For security, use SHA-256 or SHA-512. MD5 and SHA-1 are cryptographically broken and should only be used for legacy checksum verification.

Can a hash be reversed back into the original text?

Cryptographic hashes are one-way functions and cannot be reversed. However, weak passwords can be matched against precomputed rainbow tables.

Is my input data uploaded to a server?

No, all hashes are computed locally using JavaScript Web Crypto API and lightweight hashing functions.

What is a Cryptographic Hash Function?

A cryptographic hash function is a deterministic algorithm that takes an arbitrary block of data and returns a fixed-size bit string (the hash digest). A slight change to the input string produces an entirely different digest value.

Frequently Asked Questions

Are hash algorithms reversible?
No. Cryptographic hashes are one-way functions. You cannot reverse a SHA-256 or SHA-512 hash digest back into its original plain text.

Is my input text sent to a server?
No. All hash calculations are performed locally in your browser using the native Web Crypto API (window.crypto.subtle).
