La criptografía de Elide se basa en AWS-LC, una bifurcación de BoringSSL, y se identifica igual que Node cuando se compila con BoringSSL: process.versions.openssl es 1.1.1 y process.features.openssl_is_boringssl es true. Los fallos llevan las cadenas de error de AWS-LC (por ejemplo error:1e000065:Cipher functions:OPENSSL_internal:BAD_DECRYPT) con library, reason y un código ERR_OSSL_*. Ed448, X448 y OCB no están disponibles; no se puede activar el modo FIPS.

Consulte la documentación de crypto de Node.js para ver las formas estándar de los argumentos.
