Constructor Detail

PublicKey

public PublicKey(AbstractPublicKey publicKey)

PublicKey

public PublicKey()

PublicKey

public PublicKey(byte[] bytes)
          throws EncryptionError

Throws:

EncryptionError

PublicKey

public PublicKey(byte[] bytes,
                 KeyInfo info)
          throws EncryptionError

Throws:

EncryptionError

Method Detail

isPublic

public boolean isPublic()

Overrides:

isPublic in class AbstractKey

getBitStrength

public int getBitStrength()

encrypt

public byte[] encrypt(byte[] bytes)
               throws EncryptionError

Overrides:

encrypt in class AbstractKey

Throws:

EncryptionError

encrypt

public byte[] encrypt(java.lang.String plainText)
               throws EncryptionError

Throws:

EncryptionError

pack

public byte[] pack()

Overrides:

pack in class AbstractKey

verify

public boolean verify(java.io.InputStream source,
                      byte[] signature,
                      HashType hashType)
               throws java.io.IOException

Overrides:

verify in class AbstractKey

Throws:

java.io.IOException

equals

public boolean equals(java.lang.Object obj)

Keys equality check. Only public keys are equal to each other. Right now private keys can't be equal to the public even if the latter is its part.

Overrides:

equals in class java.lang.Object

Parameters:

obj - key to compare with. Should be PublicKey instaance.

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

fingerprint

public byte[] fingerprint()

Description copied from class: AbstractKey

The fingerprint of the key is a uniqie sequence of bytes that matches the key without compromising it. In fact, only public keys can have it, for symmetric keys the fingerprint will compromise it.

Therefore, the private key fingerprint is its public key fingerprint. The public key fingerprint is calculated using some hash over it's parameters, see fingerprint()

Overrides:

fingerprint in class AbstractKey

Returns:

updateDigestWithKeyComponents

public Digest updateDigestWithKeyComponents(Digest digest)

Description copied from class: AbstractKey

Arbitrary fingerprint calculation. As the digest may be different adn it might be useful to include more information than a key to it, it is possible to update some digest instance with key data.

Create any digest you need and call this method to update it with a ket data.

This can and should be used to obtain higher-order composite fingerprints for high security setups.

Overrides:

updateDigestWithKeyComponents in class AbstractKey

Returns:

same digest instance (to chain calls)

getPublicExponent

public long getPublicExponent()
