Trotz der Kritik wurde DES im November 1976 als Bundesnorm genehmigt und am 15. Januar 1977 als FIPS PUB 46 veröffentlicht, das zur Verwendung für alle nicht klassifizierten Daten zugelassen ist. | |
Es wurde später 1983, 1988 (überarbeitet als FIPS-46-1), 1993 (FIPS-46-2) und erneut 1999 (FIPS-46-3) als Standard bestätigt, wobei letzteres "Triple DES" vorschrieb ( siehe unten). | |
Am 26. Mai 2002 wurde DES nach einem öffentlichen Wettbewerb endgültig durch den Advanced Encryption Standard (AES) abgelöst. | |
Am 19. Mai 2005 wurde FIPS 46-3 offiziell zurückgezogen, aber NIST hat Triple DES bis zum Jahr 2030 für vertrauliche Regierungsinformationen genehmigt. | |

that's a lot of 0's and 1's. | |
Holy Moly! | |
200 x 200 = 40,000 | |
40,000 values to be exact. | |
Good luck decoding that! | |
Wait, I don't think decoding is the right word... | |
Well... Anyways... Good Luck! | |
hehehe... |

Here we notice that the "r" values are equal which means that deriving the private key would be easy | |
which is: |
- Clusters: Compute resources that run containerized applications
- Pods: Homogenenous set of containers that share data with a constraint which is to be deployed on the same cluster
- Replication Controllers: Engaged in management of lifecycle of pods, thus they (in a way) check if a specific number of pods are running all the time.
- Services: Basically load balancers that abstract a logical set of pods. Engaged in routing traffic to one of the pods.
- Labels: Identifiers that filter out pods(homogenous) to perform common tasks.
