When it comes to a secure TLS configuration (e.g. for HTTPS), the topic is prominently about the supported cipher suites.
I want to fully understand which part of the cipher suite has which role in a SSL/TLS connection.
So from what I un… Continue reading Role of the chosen ciphersuite in an SSL/TLS connection
Can someone please explain to me how the Cipher Feedback Mode works? From what I have read some examples have a shift register in its explanation but some examples don’t. Is there two versions of CFB and what is the differenc… Continue reading Cipher feedback mode with shift registrers
I have a report detailing weak ssh ciphers on a system. How can I dis-allow these specific weak ciphers. The common solution which I am aware of is adding the following lines in sshd_config (which is a black list approach):
… Continue reading How to disallow specific ssh ciphers and/or MACS (white list approach)
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?
Using ANON ciphers (No certificates required/used) while establishing connection and later using the username/password for authentication considered secure communication?
Are there any flaws in it, like ‘Man In The Middle’ (… Continue reading Secure communication between peers with ANON ciphers and password authentication
i am a student of bachelors in software engineering, in my final year, i just want to make my final year project regarding security, whether its a kind of encryption, cryptographic or any other but regarding the security.
Reg… Continue reading any trending idea for final year project in university regarding security [on hold]
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 …
Why are insecure outdated ciphers so w… Continue reading what is wrong with openssl ciphers?

i want to ask a question regarding the following scenario:
you have they key. you dont have the entire cipher-text. you just have part of it say 60%. is there a way to possibly decrypt that part of the cipher-text. and is thi… Continue reading is the entire ciphertext needed for decryption with key
