I am trying to connect to a server using SFTP protocol
To connect successfully, I had to do the following from the centos terminal.
sftp -o KexAlgorithms=diffie-hellman-group1-sha1 -o Ciphers=aes256-cbc USER_NAME@IP_ADDRESS
Now I want to … Continue reading Curl how to specify KexAlgorithms and Cipher [migrated]
Our program encrypts the message with RSA 1024 public key A (from specific pair A-B). Then the program sends the encrypted message to the server. The server maintains a list of public-private key pairs {An-Bn} and the server iterates over … Continue reading Message is encrypted with RSA 1024 public key A (from pair A1-B1). What is probability to decrypt with private key from different pair (A2-B2)?
Recently I conducted a SSL server test to assess the SSL configuration of my server. While the overall grade A+ was pretty good, it was found that the server supports several cipher suites that are considered weak according to SSLLabs (act… Continue reading SSLLabs’ SSLTest vs. nmap ssl-enum-ciphers
I am learning about stream ciphers, which apparently are unpopular. I just want to have a better idea of some basic algorithms that are in use or were in use till recently.
I checked:
the OTP: Apparently great but unpractical

how can i implement an encryption algorithms?
and which tool or language should I use to test a hybrid encryption algorithms ?
Currently I’m a computer science student and I intend to write a paper about hybrid encryption algorithms. I hav… Continue reading How to implement and test security of hybrid encryption algorithm? [closed]
I’m doing two tests using the openssl s_client command to identify anonymous. I did two tests:
One first test: I’m using the following command to anonymous ciphers:
openssl s_client -cipher aNULL -connect example.com:443
And I get the ans… Continue reading Identification of weak and anonymous ciphers with openssl
I need to know the key exchange of the DHE-DSS cipher suites, will it be the same as mentioned in DHE-RSA?

OpenVPN allows the use of their ‘reneg-sec’ option to renegotiate keys for the data channel at a specified interval. This helped protect against exploits like Sweet32 with 64 bit block ciphers a while ago. Apparently, only 32GB of retrieve… Continue reading Is key renegotiation necessary with a larger cipher in OpenVPN?
Forgive my inexperience with encryption, I’ve been researching this for the better part of the morning and still cannot find a smoking gun answer.
A vendor is requesting that we verify a website we utilize is secured using a specific ciphe… Continue reading P-384 vs. SHA384
