A system admin is planning to encrypt all objects being uploaded to S3 from an application. The system admin
does not want to implement his own encryption algorithm; instead he is planning to use server side encryption
by supplying his own key (SSE-C). Which parameter is not required while making a call for SSE-C?

A.
x-amz-server-side-encryption-customer-key-AES-256

B.
x-amz-server-side-encryption-customer-key

C.
x-amz-server-side-encryption-customer-algorithm

D.
x-amz-server-side-encryption-customer-key-MD5

Explanation:
AWS S3 supports client side or server side encryption to encrypt all data at rest. The server side encryption
can either have the S3 supplied AES-256 encryption key or the user can send the key along with each API call
to supply his own encryption key (SSE-C.. When the user is supplying his own encryption key, the user has to
send the below mentioned parameters as a part of the API calls:
x-amz-server-side-encryption-customer-algorithm: Specifies the encryption algorithm
x-amz-server-side-encryption-customer-key: To provide the base64-encoded encryption key
x-amz-server-side-encryption-customer-key-MD5: To provide the base64-encoded 128-bit MD5 digest of the
encryption key
