  • What are Asymmetric algorithms?

    Asymmetric algorithms are very important in cryptography and especially in digital signatures. The first asymmetric cryptography algorithms were introduced by Whitfield Diffie and Martin Hellman in the 1970s. The main difference between classical and symmetric cryptography is that instead of using a key to encrypt and decrypt, you should now use a pair of keys. […]

We can use a digital signature to verify the author of the signature, to authenticate the content of the message. Also, third parties must […]
