various tools and services. Here’s

a brief guide to the most common

encryption standards

AES Advanced Encryption Standard (AES) – also known as Rijndael – is the industry-standard symmetric encryption algorithm used by the US government to protect classified information. It’s considered

impervious to all attacks. AES offers three different key lengths: its default of 128-bits, along with keys of 192 and 256 bits for heavy-duty encryption purposes.

Camellia This Japanese-developed symmetric algorithm is used by popular encryption programs such as VeraCrypt and GNU Privacy Guard. Like AES, it creates keys of 128, 192 and 256 bits and has never been broken. Camellia is also used by TLS, the standard technology for creating an encrypted link between websites and your browser.

Twofish Twofish is a symmetric encryption algorithm that creates key sizes of up to 256 bits. It’s renowned for being fast, flexible and efficient, and is often the encryption algorithm used by password-management tools and secure-payment systems.

RSA RSA is an asymmetric encryption algorithm that creates keys with at least 128 bits. RSA keys of this length have been broken in a matter of seconds, so security experts now recommend that keys of 1,024 bits or more be used.

Triple DES The original Data Encryption Standard (DES) algorithm was eventually recognised as being easy to crack. It was replaced by Triple DES, which uses three keys of 56 bits each (168 bits in total) – once considered the industry standard – but this, too, is now being phased out.
