deslength

In January 1999, distributed.net and the Electronic Frontier Foundation collaborated to publicly break a DES key in 22 hours and 15 minutes (see § Chronology).

2023年9月20日 — This article talks about the Data Encryption Standard (DES), a historic encryption algorithm known for its 56-bit key length.

The Data Encryption Standard (DES) is a block cipher and was introduced by NIST in 1974. It has a 56-bit key size that makes it vulnerable to brute force ...

Triple-length keys are 192-bits in length. Additional triple-length DES key support is introduced by APAR OA55184 for ICSF FMID HCR77C1 and later releases and ...

2017年9月15日 — DES has a 56-bit key in 8-bytes. The length of the output depends on the length of the input, mode and padding, not the key.

DES uses a 64-bit key, but because eight of those bits are used for parity checks, the effective key length is only 56 bits. The encryption algorithm generates 16 different 48-bit subkeys, one for each of the 16 encryption rounds.

2021年6月25日 — Basic DES uses a 56-bit effective key length, which is way too short to be anywhere near secure in 2020. Even Triple-DES, with its 56*3=168 bit ...

Key length is 56 bits. DES is insecure due to the relatively short 56-bit key size. Important Points. Broad level steps of DES are: In first step, 64 – bit ...

這個演算法因為包含一些機密設計元素，相對短的金鑰長度以及懷疑內含美國國家安全局（NSA）的後門而在開始時有爭議，DES因此受到了強烈的學院派式的審查，並以此推動了現代 ...
