Method Detail

encrypt

byte[] encrypt(byte[] data)

Encrypts the source data

encrypt

ByteBuffer encrypt(ByteBuffer data)

Encrypts the contents of the input ByteBuffer into a new ByteBuffer instance. The returned instance will be at position 0 and ready to read.

decrypt

byte[] decrypt(byte[] encryptedData)

Decrypts encrypted data

decrypt

ByteBuffer decrypt(ByteBuffer encryptedData)

Decrypts the given ByteBuffer contents and returns them in a new ByteBuffer. The returned instance will be at position 0 and ready to read.

destroy

void destroy()

Destroy encryption key preventing future use. Implementations should allow this to be called multiple times without failing.

isDestroyed

boolean isDestroyed()

Indicates whether destroy() has already been called to destroy the cipher
