MD5 is the most suitable option from a performance perspective for maintaining file integrity checks on a cloud object store. Although it is less secure than SHA-256 and SHA-512, MD5 is computationally less intensive and faster, especially for large files. AES is an encryption algorithm and not applicable for hashing. Therefore, MD5 strikes a better balance between speed and utility for the given requirement.
From a performance perspective, the most suitable hashing algorithm for maintaining file integrity checks on a cloud object store would be MD5 (option C). MD5 is faster compared to SHA-256 and SHA-512, especially for large files. While SHA-256 and SHA-512 are more secure and resistant to collision attacks compared to MD5, they are also computationally more intensive and thus slower. AES (option D) is not a hashing algorithm but a symmetric encryption algorithm used for securing data at rest. It's not suitable for file integrity checks through hashing. Therefore, in terms of performance, MD5 would be the most appropriate choice among the options provided. However, it's important to note that MD5 is considered less secure than SHA-256 and SHA-512, so depending on the level of security required, SHA-256 might be preferred despite its higher computational overhead.
Hashing files with MD5, since it's weaker/simpler, will hash faster than SHA256 which will be faster than SHA512. AES is an encryption standard.
Agree with what everyone else said. MD5 not the most secure, but faster than SHA-256/512.
