## Is 3DES 168 secure?

Short answer, No. The short answer with supporting evidence is no, because it has been deprecated by the NIST since 2017 for new applications and for all applications by 2023. It has been superseded by the more robust and longer key lengths of AES.

**Is Triple DES strong?**

Therefore, by practical reasoning, Triple DES is about as strong as 128-bit ciphers.

### Why is 3DES still used?

First introduced in 1998, the 3DES algorithm is still broadly adopted in finance, payment and other private industry to encrypt data in-transit and at-rest, including EMV keys for protecting credit card transactions.

**Why is 3DES not secure?**

Triple DES using 3 different keys is still considered secure because there are no known attack which completely break its security to a point where it is feasible nowadays to crack it.

## How fast is 3DES?

2.5 Compared Algorithms

Algorithm | Megabytes(2^20 bytes) Processed | MB/Second |
---|---|---|

Rijndael (128) CBC | 256 | 55.447 |

DES | 128 | 21.340 |

(3DES)DES-XEX3 | 128 | 20.783 |

(3DES)DES-EDE3 | 64 | 9.848 |

**How easy is it to crack 3DES?**

In terms of rank, 3DES is not the most secure algorithm, but that doesn’t mean that it’s going to be easy for you to break. While 3DES can be broken via bruteforce, it’s still not necessarily trivial to do.

### Is Triple DES safe?

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. Triple DES provides much stronger encryption than ordinary DES but it is less secure than advanced encryption standard (AES).

**Why is DES better than triple?**

Triple DES runs three times slower than DES, but is much more secure if used properly. The procedure for decrypting something is the same as the procedure for encryption, except it is executed in reverse. Like DES, data is encrypted and decrypted in 64-bit chunks.

## Is 3DES considered weak?

The 3DES cipher suffers from a fundamental weakness linked to its small (64-bit) blocksize, i.e. the size of plaintext that it can encrypt. In the common mode of operation CBC, each plaintext block is XORed with the previous ciphertext before encryption.

**Why is the 3DES weak?**

### How many secret bits are there in a 3DES key?

3DES is simply three DES encryptions with two different keys, for an effective 112 bit key; or with three different keys, for an effective 168 bit key. AES (Advanced Encryption Standard). Block size: 128 bits; key size: 128, 192, or 256 bits.
