Sweet32: Birthday attacks on 64-bit block ciphers in TLS and OpenVPNSweet32: Birthday attacks on 64-bit block ciphers in TLS and OpenVPN Cryptographic protocols like TLS, SSH, IPsec, and OpenVPN commonly use block cipher algorithms, such as AES, Triple-DES, and Blowfish, to encrypt data between clients and servers. To use such algorithms, the data is broken into fixed-length chunks, called blocks, and each block is encrypted separately according to a mode of opera
