Method Detail

setEncryptionKeysAES

int setEncryptionKeysAES(byte[] keys)

Set both keys to different values, if keys.length == 2 * KEY_SIZE, else set both keys to the same value.

Parameters:

keys - Array which contains key(s) (send and receive key)

Returns:

int

setEncryptionKeysAES

int setEncryptionKeysAES(byte[] keys,
                         int offset,
                         int keylen)

Set both keys to different values, if keys.length == 2 * KEY_SIZE, else set both keys to the same value.

Parameters:

keys - Array which contains key(s) (send and receive key)

Returns:

int

getKeys

byte[] getKeys()

Returns the currently used key(s) for encryption/decryption. If both keys are set, then an array of 32 byte is returned, otherwise an array of 16 bytes is returned.

Returns:

The current key(s) used for encryption/decryption or null, if no key is set.
