crypto.publicDecrypt(key, buffer)

• key <Object> | <string> | <ArrayBuffer> | <Buffer> | <TypedArray> | <DataView> | <KeyObject> | <CryptoKey>

  • passphrase <string> | <ArrayBuffer> | <Buffer> | <TypedArray> | <DataView> 可选的私钥密码。

    ¥passphrase <string> | <ArrayBuffer> | <Buffer> | <TypedArray> | <DataView> An optional passphrase for the private key.

  • padding <crypto.constants> crypto.constants 中定义的可选填充值，可能是：crypto.constants.RSA_NO_PADDING 或 crypto.constants.RSA_PKCS1_PADDING。

    ¥padding <crypto.constants> An optional padding value defined in crypto.constants, which may be: crypto.constants.RSA_NO_PADDING or crypto.constants.RSA_PKCS1_PADDING.

  • encoding <string> 当 buffer、key 或 passphrase 是字符串时使用的字符串编码。

    ¥encoding <string> The string encoding to use when buffer, key, or passphrase are strings.

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

• 返回：<Buffer> 带有解密内容的新 Buffer。

  ¥Returns: <Buffer> A new Buffer with the decrypted content.

使用 key.buffer 解密 buffer 之前使用相应的私钥加密，例如使用 crypto.privateEncrypt()。

¥Decrypts buffer with key.buffer was previously encrypted using the corresponding private key, for example using crypto.privateEncrypt().

如果 key 不是 KeyObject，则此函数的行为就像将 key 传给 crypto.createPublicKey() 一样。如果是对象，则可以传入 padding 属性。否则，该函数使用 RSA_PKCS1_PADDING。

¥If key is not a KeyObject, this function behaves as if key had been passed to crypto.createPublicKey(). If it is an object, the padding property can be passed. Otherwise, this function uses RSA_PKCS1_PADDING.

由于 RSA 公钥可以从私钥派生，因此可以传入私钥而不是公钥。

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