In a cipher suite like "TLS_DHE_RSA_WITH_AES_256_CBC_MD5" RSA is used for authentication, while AES (256 bit) in CBC mode is used for encryption. Authentication is needed since Diffie-Hellman is vulnerable to Man-in-the-Middle attacks. An attacker could easily exchange the Diffie-Hellmann paramater and would therefore be able to intercept the communication ...
For the ciphers, use DHE-RSA-AES256-SHA. If you use openssl ciphers -v you can get more information about each cipher: $ openssl ciphers -v DHE-RSA-AES256-SHA DHE-RSA-AES256-SHA SSLv3 Kx=DH Au=RSA Enc=AES(256) Mac=SHA1 $ openssl ciphers -v AES256-SHA AES256-SHA SSLv3 Kx=RSA Au=RSA Enc=AES(256) Mac=SHA1 From this you can ...
A very good explanation can be found at this url: http://nakedsecurity.sophos.com/2013/11/04/anatomy-of-a-password-disaster-adobes-giant-sized-cryptographic-blunder/ The idea is exactly what mikeazo said in an other answer.
The encryption key was never published and triple DES itself is strong enough to not brute force, so you have to use some of the other mistakes to attempt to recover your password. Your options are: exploit the fact that they used ECB and use the hints. To do this you will find your encrypted password and see if other users had the same block. For example, ...
