privateKey
{Object | string | Buffer | KeyObject}oaepHash
{string} The hash function to use for OAEP padding and MGF1. Default:'sha1'
oaepLabel
{Buffer | TypedArray | DataView} The label to use for OAEP padding. If not specified, no label is used.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
{Buffer | TypedArray | DataView}- Returns: {Buffer} A new
Buffer
with the decrypted content.
Decrypts buffer
with privateKey
. buffer
was previously encrypted using
the corresponding public key, for example using [crypto.publicEncrypt()
][].
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
.
