Stateless Encryption API
AES‑256‑GCM and RSA encrypt/decrypt, key generation, and hashing — your keys, we store nothing.
Get it on RapidAPI ↗Stateless Encryption performs real cryptography over a simple JSON API, backed by Node's native crypto. Encrypt and decrypt with AES-256-GCM (authenticated) using either a 32-byte key or a password (scrypt-derived, with a returned salt); generate RSA keypairs (2048/3072/4096) and do RSA-OAEP SHA-256 encrypt/decrypt; generate random keys; and hash with SHA-256/512, SHA-1, or MD5.
Nothing is persisted — keys, passwords, plaintext, and ciphertext exist only for the request. Useful for end-to-end encryption helpers, secure token exchange, signing/verification workflows, and quick crypto debugging without wiring up libraries yourself.

Frequently asked questions
Are keys stored?
No. Keys, passwords, and plaintext are used only for the request and never saved. AES uses AES-256-GCM (authenticated); pass either a 32-byte key (hex or base64) or a password (scrypt-derived, returning a salt to store alongside the ciphertext).
What algorithms are supported?
AES‑256‑GCM and RSA‑2048/4096.
Is there a size limit?
Up to 1,000,000 characters per request (plaintext).
