• I think you are mixing things up. AES is a symmetric cipher, thus only have one key both for encryption and decryption. Asymmetric ciphers like RSA have two keys. A public key for encryption and a private key for decryption. And for reddit, you can indeed answer without being logged in.

Oct 23, 2008 Hi all, The other day a colleague of mine asked me if I had a.NET version of the C sample in How to generate key pairs, encrypt and decrypt data with CryptoAPI post. C sample calls CryptoAPI directly (and you know we can do the same thing in.NET through P/Invoke), but the idea was to use. Sep 26, 2019 Generating an SSH key. To generate an SSH key with PuTTYgen, follow these steps: Open the PuTTYgen program. For Type of key to generate, select SSH-2 RSA. Click the Generate button. Move your mouse in the area below the progress bar. When the progress bar is full, PuTTYgen generates your key pair. Type a passphrase in the Key passphrase field.

Hi all,

The other day a colleague of mine asked me if I had a .NETversion of the C++ sample in How to generate key pairs, encrypt and decrypt data with CryptoAPI post. C++ sample calls CryptoAPI directly (and you know we can do the same thing in .NET through P/Invoke), but the idea was to use System.Security classes in order to get a pure .NET solution. The answer is yes, I have such sample, and here it is:

If you compare both samples you will see that .NET simplifies the task a lot. But sometimes we won't be able to do with System.Security classes exactly the same we can do with CryptoAPI. So don't forget about the API just yet!

I hope this helps.

Generate Public And Private Key Pair With Aes 256 Number

Private Key and public key are a part of encryption that encodes the information. Both keys work in two encryption systems called symmetric and asymmetric. Symmetric encryption (private-key encryption or secret-key encryption) utilize the same key for encryption and decryption. Asymmetric encryption utilizes a pair of keys like public and private key for better security where a message sender encrypts the message with the public key and the receiver decrypts it with his/her private key.

Public and Private key pair helps to encrypt information that ensures data is protected during transmission.

Public Key

Public key uses asymmetric algorithms that convert messages into an unreadable format. A person who has a public key can encrypt the message intended for a specific receiver. The receiver with the private key can only decode the message, which is encrypted by the public key. The key is available via the public accessible directory.

Private Key

The private key is a secret key that is used to decrypt the message and the party knows it that exchange message. In the traditional method, a secret key is shared within communicators to enable encryption and decryption the message, but if the key is lost, the system becomes void. To avoid this weakness, PKI (public key infrastructure) came into force where a public key is used along with the private key. PKI enables internet users to exchange information in a secure way with the use of a public and private key.

Key Size and Algorithms

There are RSA, DSA, ECC (Elliptic Curve Cryptography) algorithms that are used to create a public and private key in public key cryptography (Asymmetric encryption). Due to security reason, the latest CA/Browser forum and IST advises to use 2048-bit RSA key. The key size (bit-length) of a public and private key pair decides how easily the key can be exploited with a brute force attack. The more computing power increases, it requires more strong keys to secure transmitting data.
