Restricted

Summary

Sign UTF-8 string data using a private key and algorithm (for example SHA256withRSA). Returns Base64 signature text. privateKey should normally be provided as a secret reference such as {{signing.key.main}} from generatePrivateKey.privateKeySecretRef. Supported signature algorithms include SHA256withRSA and Ed25519.
