crypto.publicDecrypt(key, buffer)


使用 key.buffer 解密 buffer 之前使用相应的私钥加密,例如使用 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

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。

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

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.

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