The DES and Triple DES ciphers, as used in the TLS, SSH, and IPSec
protocols and other protocols and products, have a birthday bound of
approximately four billion blocks, which makes it easier for remote
attackers to obtain cleartext data via a birthday attack against a
long-duration encrypted session, as demonstrated by an HTTPS session using
Triple DES in CBC mode, aka a “Sweet32” attack.

Notes
| Author | Note |
|---|---|
| mdeslaur | DES ciphers aren’t typically selected as there are other stronger ciphers placed earlier in default cipher lists gnutls puts AES before 3DES in the cipher list |
