publicEncrypt - node__crypto.d.ts - Node

function publicEncrypt

Usage in Deno

```typescript import { publicEncrypt } from "node:node__crypto.d.ts"; ```



publicEncrypt(key: RsaPublicKey
 | RsaPrivateKey
 | KeyLike,
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](../.././node__crypto.d.ts/~/privateDecrypt). If `key` is not a `KeyObject`, this function behaves as if `key` had been passed to [createPublicKey](../.././node__crypto.d.ts/~/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



key: RsaPublicKey
 | RsaPrivateKey
 | KeyLike



buffer: ArrayBufferView

Return Type

Buffer
