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
Buffer
with 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.
