crypto.createPrivateKey(key)
key
<Object> | <string> | <ArrayBuffer> | <Buffer> | <TypedArray> | <DataView>key
: <string> | <ArrayBuffer> | <Buffer> | <TypedArray> | <DataView> | <Object> 密钥材料,采用 PEM、DER 或 JWK 格式。format
: <string> 必须是'pem'
、'der'
或 ''jwk'
。 默认值:'pem'
。type
: <string> 必须是'pkcs1'
、'pkcs8'
或'sec1'
。 仅当format
为'der'
时才需要此选项,否则将被忽略。passphrase
: <string> | <Buffer> 用于解密的密码。encoding
: <string> 当key
是字符串时使用的字符串编码。
- 返回: <KeyObject>
创建并返回包含私钥的新密钥对象。
如果 key
是字符串或 Buffer
,则假定 format
是 'pem'
;否则,key
必须是具有上述属性的对象。
如果私钥被加密,则必须指定 passphrase
。
密码的长度限制为 1024 字节。

<Object> | <string> | <ArrayBuffer> | <Buffer> | <TypedArray> | <DataView>key
: <string> | <ArrayBuffer> | <Buffer> | <TypedArray> | <DataView> | <Object> The key material, either in PEM, DER, or JWK format.format
: <string> Must be'pem'
,'der'
, or ''jwk'
. Default:'pem'
.type
: <string> Must be'pkcs1'
,'pkcs8'
or'sec1'
. This option is required only if theformat
is'der'
and ignored otherwise.passphrase
: <string> | <Buffer> The passphrase to use for decryption.encoding
: <string> The string encoding to use whenkey
is a string.
- Returns: <KeyObject>
Creates and returns a new key object containing a private key. If key
is a
string or Buffer
, format
is assumed to be 'pem'
; otherwise, key
must be an object with the properties described above.
If the private key is encrypted, a passphrase
must be specified. The length
of the passphrase is limited to 1024 bytes.
