public class X509EncodedKeySpec extends EncodedKeySpec
This class represents the ASN.1 encoding of a public key, encoded according to the ASN.1 type SubjectPublicKeyInfo
. The SubjectPublicKeyInfo
syntax is defined in the X.509 standard as follows:
SubjectPublicKeyInfo ::= SEQUENCE { algorithm AlgorithmIdentifier, subjectPublicKey BIT STRING }

X509EncodedKeySpec
public X509EncodedKeySpec(byte[] encodedKey)
Creates a new X509EncodedKeySpec with the given encoded key.
- Parameters:
-
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. - Throws:
-
NullPointerException
- ifencodedKey
is null.
Methods
getEncoded
public byte[] getEncoded()
Returns the key bytes, encoded according to the X.509 standard.
- Overrides:
-
getEncoded
in classEncodedKeySpec
- Returns:
- 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.
- Specified by:
-
getFormat
in classEncodedKeySpec
- Returns:
- the string
"X.509"
