- kevin_thibedeau 6y ago112-bit keys are still allowed precisely because of 3DES.
- Twirrim 6y agoReally? 3DES still appears here, https://csrc.nist.gov/projects/block-cipher-techniques https://csrc.nist.gov/projects/block-cipher-techniques, with DES and Skipjack being called out as deprecated.
- user5994461 6y agoThat page says that 3DES is prohibited from usage in new applications and is prohibited for encrypting more than 1 GB of data, since 2017. The attached documents have additional information on implementation and (non) usage, including deadline to migrate legacy military systems. It's sadly quite cumbersome to go through the tens of PDF to find the relevant information.
