crypto.privateDecrypt(privateKey, buffer)
-
privateKey<Object> | <string> | <ArrayBuffer> | <Buffer> | <TypedArray> | <DataView> | <KeyObject> | <CryptoKey>-
oaepHash<string> 用于 OAEP 填充和 MGF1 的哈希函数。默认值:'sha1'¥
oaepHash<string> The hash function to use for OAEP padding and MGF1. Default:'sha1' -
oaepLabel<string> | <ArrayBuffer> | <Buffer> | <TypedArray> | <DataView> 用于 OAEP 填充的标签。如果未指定,则不使用标签。¥
oaepLabel<string> | <ArrayBuffer> | <Buffer> | <TypedArray> | <DataView> The label to use for OAEP padding. If not specified, no label is used. -
padding<crypto.constants>crypto.constants中定义的可选填充值,可能是:crypto.constants.RSA_NO_PADDING、crypto.constants.RSA_PKCS1_PADDING或crypto.constants.RSA_PKCS1_OAEP_PADDING。¥
padding<crypto.constants> An optional padding value defined incrypto.constants, which may be:crypto.constants.RSA_NO_PADDING,crypto.constants.RSA_PKCS1_PADDING, orcrypto.constants.RSA_PKCS1_OAEP_PADDING.

buffer<string> | <ArrayBuffer> | <Buffer> | <TypedArray> | <DataView> -
返回:<Buffer> 带有解密内容的新
Buffer。¥Returns: <Buffer> A new
Bufferwith the decrypted content.
用 privateKey 解密 buffer。buffer 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.
在 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.
