Triple DES is backward compatible with regular DES. This technology is contained within the standard of ANSIX9.52. The three keys are referred to as k1, k2 and k3. Triple DES encrypts input data three times. Therefore, it may not be nearly as obsolete as deemed by NIST. Triple DES: Triple DES runs DES encryption three different times by encrypting, decrypting, and then encrypting data again.

Known for its compatibility and flexibility, software can easily be converted for Triple DES inclusion. Data Encryption Standards (DES): DES is a low-level encryption block cipher algorithm that converts plain text in blocks of 64 bits and converts them to ciphertext using keys of 48 bits. The algorithm uses a 56-bit key to encrypt data in 64-bit blocks. The Data Encryption Standard (DES) is a cipher (a method for encrypting information) selected as an official Federal Information Processing Standard (FIPS). The algorithm is based on Feistel network.
Data encryption standard (DES) is a symmetric key block cipher algorithm. It derives from single DES but the technique is used in triplicate and involves three sub keys and key padding when necessary, such as instances where the keys must be increased to 64 bits in length. Strength of Data encryption standard (DES) swethavazhakkat. Yet, it is often used in conjunction with Triple DES. Triple DES provides much stronger encryption than ordinary DES but it is less secure than advanced encryption standard (AES). Thus, the Triple DES is now considered to be obsolete. Definition (s): An implementation of the data encryption standard (DES) algorithm that uses three passes of the DES algorithm instead of one as used in ordinary DES applications. It is also a block cipher: it converts fixed. Symmet-ric key cryptography is the oldest type whereas asymmetric cryptography is only being used publicly since the late 1970’s1. DES (Data Encryption Standard) is a symmetric cipher: the very same key is used to encrypt and decrypt the data. However, the DES algorithm was replaced by the Advanced Encryption Standard by the National Institute of Standards and Technology (NIST). The Data Encryption Standard (DES) As mentioned earlier there are two main types of cryptography in use today -symmet-ric or secret key cryptography and asymmetric or public key cryptography. Triple DES is advantageous because it has a significantly sized key length, which is longer than most key lengths affiliated with other encryption modes.
Developed in the early 1970s at IBM and based on an earlier. Although its short key length of 56 bits makes it too insecure for modern applications, it has been highly influential in the advancement of cryptography. The triple DES key length contains 168 bits but the key security falls to 112 bits. The Data Encryption Standard ( DES / diis, dz /) is a symmetric-key algorithm for the encryption of digital data.
