Date: Thu, 08 Feb 2018 09:54:58 +0100 [thread overview]
Message-ID: <1518080098-22100-1-git-send-email-erik.kapfer@ipfire.org> (raw)
[-- Attachment #1: Type: text/plain, Size: 5150 bytes --]
64 bit block ciphers like Blowfish, TDEA and CAST5 are vulnerable to the so called 'Birthday attacks' .
Infos for 'Sweet32' Birthday attacks can be found in here
https://sweet32.info/ .
An Overview of 64 bit clock ciphers can also be found in here
http://en.citizendium.org/wiki/Block_cipher/Catalogs/Cipher_list#64-bit_blocks
1024 bit Diffie-Hellman parameter has also been marked as weak causing the 'Logjam Attack' .
