Re: [openssl-users] AES CBC approved encryption algorithm/option in FIPS

2015-03-20 Thread Jeremy Farrell
I assume it says it is a FIPS 140-2 approved mode because it is approved by FIPS 140-2 ;). Don't confuse the concepts of being 'FIPS approved' or 'FIPS compliant' with being 'secure'. They are not the same thing, and can sometimes conflict. On 20/03/2015 12:01, Philip Bellino wrote: Hello,

Hello, I am using the Openssl-1.0.2 with openssl-fips-2.0.9 and have a question? If AES CBC Encryption is considered vulnerable to an attacker with the capability to inject arbitrary traffic into the plain-text stream, then why is it listed as an approved algorithm/option in table 4A on page 14

We only use OpenSSL_add_all_algorithms during SSL initialization, no other SSL_[CTX]_set_cipher_list calls are made, therefore the cipher used should be the default DHE-RSA-AES256-SHA then. Alex On Oct 14, 2012, at 3:01 PM, Dave Thompson wrote: >> From: owner-openssl-us...@openssl.org On Behal

Hi all, my question may not be directly related to OpenSSL, but I don't know where else better to seek for answer, so... I'm curious to know, given a number of cipher texts, how hard it is to know, if at all possible, what algorithm was used to generate that? Chris _

Hi The browsers send a prioritised list of ciphers to the server for selection, strong first, followed by the weaker ones. The server selects the first cipher that matches. So the server should typically select the strongest possible common cipher. :) Amit. [EMAIL PROTECTED] wrote: > Steve,
