Method Details

getAlgorithm

public String getAlgorithm()

Specified by:

getAlgorithm in interface Key

Overrides:

getAlgorithm in class EncodedKeySpec

getEncoded

public byte[] getEncoded()

Specified by:

getEncoded in interface Key

Overrides:

getEncoded in class X509EncodedKeySpec

getAlgorithmIdentifier

public AlgorithmIdentifier getAlgorithmIdentifier()

getSubjectPublicKey

public BIT_STRING getSubjectPublicKey()

getTag

public Tag getTag()

Description copied from interface: ASN1Value

Returns the base tag for this type, not counting any tags that may be imposed on it by its context.

Specified by:

getTag in interface ASN1Value

Returns:

Base tag.

encode

public void encode(OutputStream ostream)
            throws IOException

Description copied from interface: ASN1Value

Write this value's DER encoding to an output stream using its own base tag.

Specified by:

encode in interface ASN1Value

Parameters:

ostream - Output stream.

Throws:

IOException - If an error occurred.

encode

public void encode(Tag implicit,
 OutputStream ostream)
            throws IOException

Description copied from interface: ASN1Value

Write this value's DER encoding to an output stream using an implicit tag.

Specified by:

encode in interface ASN1Value

Parameters:

implicit - Implicit tag.

ostream - Output stream.

Throws:

IOException - If an error occurred.

getTemplate

public static SubjectPublicKeyInfo.Template getTemplate()

toPublicKey

public PublicKey toPublicKey()
                      throws NoSuchAlgorithmException,
InvalidKeyFormatException

Creates a PublicKey from the public key information. Currently only RSA and DSA keys can be converted.

Throws:

NoSuchAlgorithmException - If the cryptographic provider does not recognize the algorithm for this public key.

InvalidKeyFormatException - If the subjectPublicKey could not be decoded correctly.
