	)

3DES-CBC buffer encryption/decryption

Note: Upon exit, the content of the IV is updated so that you can call the function same function again on the following block(s) of data and get the same result as if it was encrypted in one call. This allows a "streaming" usage. If on the other hand you need to retain the contents of the IV, you should either save it manually or use the cipher module instead.

Parameters

ctx	3DES context
mode	MBEDTLS_DES_ENCRYPT or MBEDTLS_DES_DECRYPT
length	length of the input data
iv	initialization vector (updated after use)
input	buffer holding the input data
output	buffer holding the output data
