Detailed explanation-1: -Triple-DES is the extended version of DES which applies DES three times with two 56-bit keys. International data encryption algorithm (IDEA) is a block cipher method similar to DES. It operates on 64-bit blocks of plaintext and uses a 128-bit key. The algorithm can be implemented either in hardware or software.

Detailed explanation-2: -As the security weaknesses of DES became more apparent, 3DES was proposed as a way of extending its key size without having to build an entirely new algorithm. Rather than using a single key as in DES, 3DES runs the DES algorithm three times, with three 56-bit keys: Key one is used to encrypt the plaintext.

Detailed explanation-3: -3DES is an encryption algorithm widely used in the finance industry. It improves upon the earlier block cipher DES and brings various benefits, such as its ease of implementation in hardware and software and its widespread support among cryptographic libraries and protocols.
