How to use RSA for both authentication and secrecy?
I had this question in my mind. And the doubt was cleared off recently. So, I thought of posting it here to have a discussion about that. In addition to that, I would like to learn more about these things! Curious indeed!
RSA(Rivest, Adi Shamir and Adleman) also known as asymmetric cryptography is a public key encryption algorithm. It is based on the mathematical part which is easy to find and multiply large prime numbers together. For authentication, we can encrypt the hash(MD4/SHA) of the data with the private key. This is termed as digital signature. Confidentiality is achieved by encrypting the data with the public key and decrypting with the private key.
I was on this topic as I was researching about the different security techniques. To be precise, the cyber security in detail. Recently, I had used network security solutions too. Till date, it was beneficial. Has anyone used these in your businesses? Would love to hear from you guys!
Just sprinkle your thoughts below!
Thanks in advance!
