Method Detail

getEncoded

public byte[] getEncoded()
                  throws SshException

Description copied from interface: SshPublicKey

Encode the public key into a blob of binary data, the encoded result will be passed into init to recreate the key.

Specified by:

getEncoded in interface SshPublicKey

Returns:

an encoded byte array

Throws:

SshException

getFingerprint

public java.lang.String getFingerprint()
                                throws SshException

Description copied from interface: SshPublicKey

Return an SSH fingerprint of the public key

Specified by:

getFingerprint in interface SshPublicKey

Returns:

String

Throws:

SshException

init

public void init(byte[] blob,
                 int start,
                 int len)
          throws SshException

Description copied from interface: SshPublicKey

Initialize the public key from a blob of binary data.

Specified by:

init in interface SshPublicKey

Throws:

SshException

getAlgorithm

public java.lang.String getAlgorithm()

Description copied from interface: SshPublicKey

Get the algorithm name for the public key.

Specified by:

getAlgorithm in interface SshPublicKey

the algorithm name, for example "ssh-dss"

verifySignature

public boolean verifySignature(byte[] signature,
                               byte[] data)

Description copied from interface: SshPublicKey

Verify the signature.

Specified by:

verifySignature in interface SshPublicKey

Overrides:

verifySignature in class com.maverick.crypto.publickey.RsaPublicKey
