Question

Which type of encryption is the fastest to use for large amounts of data?

Answer 1

A larger sample size would be able to give better results.

To ascertain the impact of soil or water on the plant he can take some part for soil observation, another part for water and last part for both and then mark the differences in the observations.

Answer 2

Symmetric encryption.

Symmetric-key algorithms are algorithms are used for the process of cryptography which utilizes the same cryptographic codes for both encryptions and decryption of plaintext and ciphertext. The keys may be equal or there may be a simplistic transformation to operate within the two keys.

In symmetric-key encryption, each processor has a hidden key (code) that it can utilize to encrypt a packet of data before it is transmitted over the interface to another computer.
