Method Detail

setEncryptionKeyAES

int setEncryptionKeyAES(byte[] key)

Sets the AES encryption key to the value in the key buffer. Required length and error handling is implementation specific.

Parameters:

key -

Returns:

0 if successful, -1 if an error occurred

setEncryptionKeyAES

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

setEncryptionKeysAES

int setEncryptionKeysAES(byte[] keys)

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

Parameters:

keys - byte[]

Returns:

int

getKeys

byte[] getKeys()

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

Returns:

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

setIV2

void setIV2(byte[] buff)

encryptAES1

int encryptAES1(byte[] from,
                int ifrom,
                byte[] to,
                int ito,
                int len)

encryptAES2

int encryptAES2(byte[] buff)
