Frequently Asked Questions

What hash algorithms are supported?

We support MD5, SHA-1, SHA-256, SHA-384, SHA-512, and more. We also support HMAC (keyed-hash) for all SHA variants, and RSA encryption/decryption.

What is the difference between hashing and encryption?

Hashing is a one-way process that converts data into a fixed-length digest — it cannot be reversed. Encryption is two-way: data is encrypted with a key and can be decrypted back to the original.

Are my cryptographic operations secure?

Yes. All operations run locally in your browser using the Web Crypto API. No data is sent to any server, making it safe for sensitive use cases.
