crypto

The node:crypto ↗︎ module provides cryptographic functionality that includes a set of wrappers for OpenSSL's hash, HMAC, cipher, decipher, sign, and verify functions.

All node:crypto APIs are fully supported in Workers with the following exceptions:

• The functions generateKeyPair ↗︎ and generateKeyPairSync ↗︎ do not support DSA or DH key pairs.
• argon2 and argon2Sync are not supported.
• ed448 and x448 curves are not supported.
• It is not possible to manually enable or disable FIPS mode ↗︎.

The full node:crypto API is documented in the Node.js documentation for node:crypto ↗︎.

The WebCrypto API is also available within Cloudflare Workers. This does not require the nodejs_compat compatibility flag.
