crypto.privateEncrypt(privateKey, buffer)
privateKey
<Object> | <string> | <Buffer> | <KeyObject>key
<string> | <Buffer> | <KeyObject> PEM 编码的私钥。passphrase
<string> | <Buffer> 可选的私钥密码。padding
<crypto.constants>crypto.constants
中定义的可选填充值,可以是:crypto.constants.RSA_NO_PADDING
或crypto.constants.RSA_PKCS1_PADDING
。
buffer
<Buffer> | <TypedArray> | <DataView>- 返回: <Buffer> 带有加密内容的新
Buffer
。
用 privateKey
加密 buffer
。
返回的数据可以使用相应的公钥解密,例如使用 crypto.publicDecrypt()
。
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_PADDING
。
privateKey
<Object> | <string> | <Buffer> | <KeyObject>key
<string> | <Buffer> | <KeyObject> A PEM encoded private key.passphrase
<string> | <Buffer> An optional passphrase for the private key.padding
<crypto.constants> An optional padding value defined incrypto.constants
, which may be:crypto.constants.RSA_NO_PADDING
orcrypto.constants.RSA_PKCS1_PADDING
.
buffer
<Buffer> | <TypedArray> | <DataView>- Returns: <Buffer> A new
Buffer
with the encrypted content.
Encrypts buffer
with privateKey
. The returned data can be decrypted using
the corresponding public key, for example using crypto.publicDecrypt()
.
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_PADDING
.
