The series of random bits created by a random bit generator, unique for every encryption operation, that you want
Elastic Transcoder to use to encrypt your files. The initialization vector must be base64-encoded, and it must be
exactly 8 bytes long before being base64-encoded. If no initialization vector is provided, Elastic Transcoder
generates one for you.
