To generate self signed certificate for AES128-SHA256 cipher using openssl, following commands are used.
AES128-SHA256 cipher commands :-
openssl genrsa -aes128 -out 1.key 2048
openssl req -config csr.conf-new -key 1.key… Continue reading selft signed certificate for AES128-GCM-SHA256 cipher
First off, please let me explain why I’m asking this at all:
The default implementation of EnvelopedCms is using AlgorithmIdentifier which by itself will use RSA_DES_EDE3_CBC or OID
1.2.840.113549.3.7 as encryption algorithm… Continue reading What would be a better encryption algorithm then RSA_DES_EDE3_CBC?

Scope:
I am considerable new on cryptography and only know some basic fundamentals of it.
Looking at yaSSL ciphers I am trying to, as an exercise, to figure out which ones are still safe to use by today’s standards and whic… Continue reading Given the following yaSSL ciphers, how do I know what’s being used?
Does changing the cipher list for a CTX object (using SSL_CTX_set_cipher_list), have any effect on the already established connections (connections that had used that very CTX object)?

I used openssl recently and noticed that in the cipher list there is AES (what else ) and then I saw many rarely used ciphers like camellia and seed, then I saw stuff like rc4, rc2 …

I understand there are quite a few posts regarding my error message, and I have looked at them with no luck to resolving my own issue.

I need to know if Mozilla Firfox implements the SCSV which adds a specific ciphersuite in case if the client initial hello message is resent (either due to MITM or due to network erro).
I opened about:config and checked the… Continue reading Does Firefox implements SCSV?
