function publicEncrypt

Usage in Deno

import { publicEncrypt } from "node:crypto";
publicEncrypt(
buffer: ArrayBufferView,
): Buffer

Encrypts the content of buffer with key and returns a new Buffer with encrypted content. The returned data can be decrypted using the corresponding private key, for example using privateDecrypt.

If key is not a KeyObject, this function behaves as if key had been passed to createPublicKey. If it is an object, the padding property can be passed. Otherwise, this function uses RSA_PKCS1_OAEP_PADDING.

Because RSA public keys can be derived from private keys, a private key may be passed instead of a public key.

Parameters

buffer: ArrayBufferView

Return Type

Buffer
