What is Certificate Transparency? When sensitive data is transferred between two hosts, encrypted communication like TLS is used for that purpose. And, digital certificates have a major role to play in TLS communication. A TLS server usually issues its digital...
What is DSA? DSA or Digital Signature Algorithm is an algorithm for digital signatures. The algorithm was first proposed by the National Institute of Standards and Technology (NIST) in 1991. Later, DSA was adopted as FIPS or Federal Information Processing Standard in...
What is DES? DES or Data Encryption Standard is a symmetric key algorithm that was developed in the 1970s and submitted to the National Bureau of Standards (NBS), which is now known as the National Institute of Standards and Technology (NIST). The algorithm was...
What is homomorphic encryption? Homomorphic encryption is a type of encryption that allows computation on ciphertexts. Later, when we decrypt the ciphertext, the operation performed on the ciphertext matches with the result of the operation performed on the...
An Offline Root Certificate Authority is a Certificate Authority (CA) that does not have network access and is kept in the powered-down state. Why do we need an Offline Root CA and how does an Offline Root CA work? In this article, we would discuss that in detail....
