crypto.privateDecrypt(privateKey, buffer)


privateKey 解密 bufferbuffer 之前使用相应的公钥加密,例如使用 crypto.publicEncrypt()

¥Decrypts buffer with privateKey. buffer was previously encrypted using the corresponding public key, for example using crypto.publicEncrypt().

如果 privateKey 不是 KeyObject,则此函数的行为就像将 privateKey 传给 crypto.createPrivateKey() 一样。如果是对象,则可以传入 padding 属性。否则,该函数使用 RSA_PKCS1_OAEP_PADDING

¥If privateKey is not a KeyObject, this function behaves as if privateKey had been passed to crypto.createPrivateKey(). If it is an object, the padding property can be passed. Otherwise, this function uses RSA_PKCS1_OAEP_PADDING.

crypto.privateDecrypt() 中使用 crypto.constants.RSA_PKCS1_PADDING 需要 OpenSSL 支持隐式拒绝 (rsa_pkcs1_implicit_rejection)。如果 Node.js 使用的 OpenSSL 版本不支持此功能,则尝试使用 RSA_PKCS1_PADDING 将失败。

¥Using crypto.constants.RSA_PKCS1_PADDING in crypto.privateDecrypt() requires OpenSSL to support implicit rejection (rsa_pkcs1_implicit_rejection). If the version of OpenSSL used by Node.js does not support this feature, attempting to use RSA_PKCS1_PADDING will fail.
