PublicKey

interface PublicKey : Key

java.security.PublicKey

Known Direct Subclasses

DHPublicKey, DSAPublicKey, ECPublicKey, RSAPublicKey

DHPublicKey	The interface to a Diffie-Hellman public key.
DSAPublicKey	The interface to a DSA public key.
ECPublicKey	The interface to an elliptic curve (EC) public key.
RSAPublicKey	The interface to an RSA public key.

A public key. This interface contains no methods or constants. It merely serves to group (and provide type safety for) all public key interfaces. Note: The specialized public key interfaces extend this interface. See, for example, the DSAPublicKey interface in java.security.interfaces.

Summary

Constants
static Long	`serialVersionUID` The class fingerprint that is set to indicate serialization compatibility with a previous version of the class.

Inherited functions

From class Key

String!

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.

ByteArray!

getEncoded()

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

String!

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".

Constants

serialVersionUID
