Encryption

The series of random bits created by a random bit generator, unique for every encryption operation, that you used to encrypt your input files or that you want Elastic Transcoder to use to encrypt your output files. The initialization vector must be base64-encoded, and it must be exactly 16 bytes long before being base64-encoded.

The data encryption key that you want Elastic Transcoder to use to encrypt your output file, or that was used to encrypt your input file. The key must be base64-encoded and it must be one of the following bit lengths before being base64-encoded:

The MD5 digest of the key that you used to encrypt your input file, or that you want Elastic Transcoder to use to encrypt your output file. Elastic Transcoder uses the key digest as a checksum to make sure your key was not corrupted in transit. The key MD5 must be base64-encoded, and it must be exactly 16 bytes long before being base64-encoded.

The specific server-side encryption mode that you want Elastic Transcoder to use when decrypting your input files or encrypting your output files. Elastic Transcoder supports the following options:
