	)

Decrypts triple DES using OFB block mode with three keys.

Parameters

	instance	LTC module instance number
	ciphertext	Input ciphertext to decrypt
	inputSize	Size of input data in bytes
	iv	Input unique input vector. The OFB mode requires that the IV be unique for each execution of the mode under the given key.
	key1	First input key for key bundle
	key2	Second input key for key bundle
	key3	Third input key for key bundle
[out]	plaintext	Output plaintext

Returns: Status from encrypt/decrypt operation
