Microsoft prepares for security in a world where our old codes are easily broken. Get familiar with these technologies now ...

RSA in action. Let’s follow the RSA algorithm step by step, with an example. Let’s say Bob wants to send a private message to Alice. The first step is for Alice to generate the keys, both ...

Cryptography is the art of keeping information secret and safe by transforming it into form that unintended recipients cannot understand. It makes secure data transmission over the internet possible.

Private keys are kept secret to “ensure secure communication. Only the intended recipient can decrypt the message,” he says. Private key cryptography also uses only a single key for both encryption ...

Keeping the private key private only matters if integer factorization (or discrete logarithms, for the other major family of asymmetric encryption algorithms) remains a hard problem.

Symmetric-key encryption is what people usually think of as encryption. It allows data and messages to be scrambled using a “key” so they are indecipherable to anyone without the key.

AES — The Advanced Encryption Standard is one of the most secure symmetric encryption algorithms. It uses ciphers with 128-bit block sizes and key lengths of 128, 192, or 256 bits.

Public-key encryption relies on asymmetric keys, with one private key used to decrypt messages and a separate public key for encrypting. Users make their public key widely available.
