↳ | java.security.spec.PKCS8EncodedKeySpec |
该类表示私钥的ASN.1编码,按照ASN.1类型PrivateKeyInfo
编码。 PrivateKeyInfo
语法在PKCS#8标准中定义如下:
PrivateKeyInfo ::= SEQUENCE { version Version, privateKeyAlgorithm PrivateKeyAlgorithmIdentifier, privateKey PrivateKey, attributes [0] IMPLICIT Attributes OPTIONAL } Version ::= INTEGER PrivateKeyAlgorithmIdentifier ::= AlgorithmIdentifier PrivateKey ::= OCTET STRING Attributes ::= SET OF Attribute

PKCS8EncodedKeySpec (byte[] encodedKey)
用给定的编码密钥创建一个新的PKCS8EncodedKeySpec。
Parameters | |
---|---|
encodedKey |
byte : the key, which is assumed to be encoded according to the PKCS #8 standard. The contents of the array are copied to protect against subsequent modification. |
Throws | |
---|---|
NullPointerException |
if encodedKey is null. |
byte[] getEncoded ()
返回按照PKCS#8标准编码的关键字节。
Returns | |
---|---|
byte[] |
the PKCS #8 encoding of the key. Returns a new array each time this method is called. |
String getFormat ()
返回与此密钥规范关联的编码格式的名称。
Returns | |
---|---|
String |
the string "PKCS#8" . |
