Method Detail

setEncryptionKeyAES

public int setEncryptionKeyAES(byte[] key)

setEncryptionKeyAES

public int setEncryptionKeyAES(byte[] key,
                               int offset,
                               int len)

Parameters:

key - byte[]

offset - int

len - int if len==16 --> only the key is set; if len==32 --> key and IV is set

Returns:

int

getKey

public byte[] getKey()

Returns the currently used key for encryption.

Returns:

The current key used for encryption or null, if no key is set.

setIV2
