What encryption standard is used by OCI Object Storage to secure object data?

The correct choice is AES-256, which is the encryption standard adopted by OCI Object Storage for securing object data. AES, or Advanced Encryption Standard, is a widely used symmetric encryption algorithm known for its security and efficiency.

AES-256, in particular, uses a key size of 256 bits, providing a robust level of security that is suitable for protecting sensitive data in cloud environments. The larger the key size, the more secure the encryption process against brute-force attacks, making AES-256 a preferred choice for organizations looking to ensure their data is protected adequately.

Other options, such as AES-128 and AES-192, offer lower levels of security compared to AES-256. While they may still be effective for certain use cases, they do not provide the same strength of encryption that AES-256 does, which is critical for the storage of sensitive and valuable information in cloud services. AES-512 is not a standard option in the AES specification, which only supports key sizes of 128, 192, and 256 bits.

Overall, the use of AES-256 in OCI Object Storage highlights Oracle's commitment to providing a secure environment for object data through strong encryption practices.
