I’m sure this is a basic question, but I’m still learning so I’m hoping for some understanding.
Recently, our available ciphers changed on our load balancer which caused certain connections out of my box that communicates th… Continue reading Host Key Verification failed after Ciphers update

I am wondering whether Extended Validation (EV) Certificate ‘green bar’ on the web browser is affected by Cipher Suites. I can’t find seem to find a reference that says that apart from this answer. Though i do find weird that… Continue reading Is EV (Extended Validation) Certificate Green Bar Affected by Available Cipher Suites?
I was wondering whether TLS_ECDHE_RSA_WITH_RC4_128_SHA is secure.
We have added it within the ciphers tag of the Tomcat configuration file.
I recently got a file which I had encrypted with substitution cipher a long time ago.
I went to crack down the key and almost got it.
But I encrypted it not just with alphabets but also with numbers as well.
I checked onli… Continue reading How to decrypt a text with substitution 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?

My email provider still supports old SSL_RSA_WITH_RC4_128_SHA ciphers. What does that mean for me?
If I use an updated system (Ubuntu 16.04) and an updated client (Thunderbird 52), shouldn’t it use this ciphers?
But when t… Continue reading Using old ciphers in email security
