| ↳ | java.security.spec.X509EncodedKeySpec | |
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 } Summary

Public constructors
X509EncodedKeySpec
public X509EncodedKeySpec (byte[] encodedKey)
Creates a new X509EncodedKeySpec with the given encoded key.
| Parameters | |
|---|---|
encodedKey | byte: 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 | if encodedKey is null. |
X509EncodedKeySpec
public X509EncodedKeySpec (byte[] encodedKey, String algorithm)
Creates a new X509EncodedKeySpec with the given encoded key. This constructor is useful when subsequent callers of the X509EncodedKeySpec object might not know the algorithm of the key.
| Parameters | |
|---|---|
encodedKey | byte: 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. |
algorithm | String: the algorithm name of the encoded public key See the KeyFactory section in the Java Security Standard Algorithm Names Specification for information about standard algorithm names. |
| Throws | |
|---|---|
NullPointerException | if encodedKey or algorithm is null. |
IllegalArgumentException | if algorithm is the empty string "" |
Public methods
getEncoded
public byte[] getEncoded ()
Returns the key bytes, encoded according to the X.509 standard.
| Returns | |
|---|---|
byte[] | 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.
| Returns | |
|---|---|
String | the string "X.509". |
