diffieHellman.computeSecret(otherPublicKey[, inputEncoding][, outputEncoding])

• otherPublicKey <string> | <ArrayBuffer> | <Buffer> | <TypedArray> | <DataView>

• inputEncoding <string> otherPublicKey 字符串的 字符编码。

  ¥inputEncoding <string> The encoding of an otherPublicKey string.

• outputEncoding <string> 返回值的 字符编码。

  ¥outputEncoding <string> The encoding of the return value.

• 返回：<Buffer> | <string>

  ¥Returns: <Buffer> | <string>

使用 otherPublicKey 作为对方的公钥计算共享密钥，并返回计算出的共享密钥。使用指定的 inputEncoding 解释提供的密钥，使用指定的 outputEncoding 对密钥进行编码。如果未提供 inputEncoding，则 otherPublicKey 应为 Buffer、TypedArray 或 DataView。

¥Computes the shared secret using otherPublicKey as the other party's public key and returns the computed shared secret. The supplied key is interpreted using the specified inputEncoding, and secret is encoded using specified outputEncoding. If the inputEncoding is not provided, otherPublicKey is expected to be a Buffer, TypedArray, or DataView.

如果给定 outputEncoding，则返回一个字符串；否则，返回 Buffer。

¥If outputEncoding is given a string is returned; otherwise, a Buffer is returned.
