                                   throws java.io.IOException

Throws:

java.io.IOException

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

write

public final void write(java.io.DataOutput _index)
                 throws java.io.IOException

Description copied from class: Key

Write to disk. Take up exactly 22 bytes.

Specified by:

write in class Key

Throws:

java.io.IOException

readCHK

public static Key readCHK(java.io.DataInput raf,
                          byte algo)
                   throws java.io.IOException

equals

public boolean equals(java.lang.Object key)

Overrides:

equals in class Key

hashCode

public int hashCode()

Overrides:

hashCode in class Key

getType

public short getType()

Description copied from class: Key

Get key type

• High 8 bit ((type >> 8) & 0xFF) is the base type (BASE_TYPE or NodeSSK.BASE_TYPE).
• Low 8 bit (type & 0xFF) is the crypto algorithm. (Currently only Key.ALGO_AES_PCFB_256_SHA256 is supported).

Specified by:

getType in class Key

getRoutingKey

public byte[] getRoutingKey()

Overrides:

getRoutingKey in class Key

getFullKey

public byte[] getFullKey()

Description copied from class: Key

Get the full key, including any crypto type bytes, everything needed to construct a Key object

Specified by:

getFullKey in class Key

cryptoAlgorithmFromFullKey

public static byte cryptoAlgorithmFromFullKey(byte[] fullKey)

routingKeyFromFullKey

public static byte[] routingKeyFromFullKey(byte[] keyBuf)

compareTo

public int compareTo(Key arg0)

archivalCopy

public Key archivalCopy()

Description copied from class: Key

Get a copy of the key with any unnecessary information stripped, for long-term in-memory storage. E.g. for SSKs, strips the DSAPublicKey. Copies it whether or not we need to copy it because the original might pick up a pubkey after this call. And the returned key will not accidentally pick up extra data.

Specified by:

archivalCopy in class Key
