## What does GCM stand for in encryption? ## What are the most secure encryption algorithms?

• Here’s a list of the main algorithms, and their current reliability: AES: this is one of the most reliable encryption algorithms today. To make it most effective, though, it should use 256-bit keys, rather than the more common 128-bit. More bits mean exponentially more time to brute-force a key.

## How do you find GCM?

• To find the greatest common factor (GCF) between numbers, take each number and write it's prime factorization. Then, identify the factors common to each number and multiply those common factors together.

## Which encryption algorithm is used?

• It uses a symmetric encryption algorithm, which uses a single key for encryption and deciphering data. The standards of IDEA™ support advanced encryption keys up to 128-bits in length. Pretty good privacy ( PGP) is an encryption algorithm that is used in many email encryption protocols.

In cryptography, Galois/Counter Mode (GCM) is a mode of operation for symmetric-key cryptographic block ciphers which is widely adopted for its performance. GCM throughput rates for state-of-the-art, high-speed communication channels can be achieved with inexpensive hardware resources.  ### What are the most secure encryption algorithms?What are the most secure encryption algorithms?
