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(java.io.OutputStream ostream)
            throws java.io.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:

java.io.IOException - If an error occurred.

encode

public void encode(Tag implicit,
                   java.io.OutputStream ostream)
            throws java.io.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:

java.io.IOException - If an error occurred.

getTemplate

public static SubjectPublicKeyInfo.Template getTemplate()

toPublicKey

public java.security.PublicKey toPublicKey()
                                    throws java.security.NoSuchAlgorithmException,
                                           InvalidKeyFormatException

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

Throws:

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

InvalidKeyFormatException - If the subjectPublicKey could not be decoded correctly.
