JCOEncodedBytes edu.virtualschool.jco.unfinished.JCODHPublicKey.encode (   ) 
 

Construct an encoded representation of this object suitable for disk storage.

final String edu.virtualschool.jco.unfinished.JCODHPublicKey.getAlgorithm (   ) 
 

Returns the standard algorithm name for this key. For example, "DSA" would indicate that this key is a DSA key. See Appendix A in the Java Cryptography Architecture API Specification & Reference for information about standard algorithm names.

Returns:
the name of the algorithm associated with this key.

Implements edu.virtualschool.jco.JCOKey.

byte [] edu.virtualschool.jco.unfinished.JCODHPublicKey.getEncoded (   ) 
 

Returns the key in its primary encoding format, or null if this key does not support encoding.

Returns:
the encoded key, or null if the key does not support encoding.

final String edu.virtualschool.jco.unfinished.JCODHPublicKey.getFormat (   ) 
 

Returns the name of the primary encoding format of this key, or null if this key does not support encoding. The primary encoding format is named in terms of the appropriate ASN.1 data format, if an ASN.1 specification for this key exists. For example, the name of the ASN.1 data format for public keys is SubjectPublicKeyInfo, as defined by the X.509 standard; in this case, the returned format is "X.509". Similarly, the name of the ASN.1 data format for private keys is PrivateKeyInfo, as defined by the PKCS #8 standard; in this case, the returned format is "PKCS#8".

Returns:
the primary encoding format of the key.
