构造器详细资料

X509EncodedKeySpec

public X509EncodedKeySpec(byte[] encodedKey)

Creates a new X509EncodedKeySpec with the given encoded key.

参数:

encodedKey - the key, which is assumed to be encoded according to the X.509 standard. The contents of the array are copied to protect against subsequent modification.

抛出:

NullPointerException - if encodedKey is null.

方法详细资料

getEncoded

public byte[] getEncoded()

Returns the key bytes, encoded according to the X.509 standard.

覆盖:

getEncoded 在类中 EncodedKeySpec

返回:

the X.509 encoding of the key. Returns a new array each time this method is called.

getFormat

public final String getFormat()

Returns the name of the encoding format associated with this key specification.

指定者:

getFormat 在类中 EncodedKeySpec

返回:

the string "X.509".
