Word Software - Public Key Online For Free

The two keys are called the ?public key? and the ?private key? of the user. The network also has a public key and a private key. The sender uses a public key to encrypt the message. The recipient uses its private key to decrypt the message.

Data encrypted with the public key can only be decrypted with the private key. Because of this use of two keys instead of one, public key cryptography is also known as asymmetric cryptography.

RSA messages are to be decrypted by the private key, not the public key. That's what ?public key encryption? is all about. The public key encrypts, the private key decrypts. I'm not going to regurgitate the detaiuls of the RSA algorithm, which are widely available online including on Wikipedia.

A RSA public key consists in two integers, the modulus (n) and the public exponent (e). It is normally encoded as an ASN. 1 structure that is a SEQUENCE of two INTEGER values. That structure is then supposed to be DER-encoded to form a PKCS#1 encoded public key.

To generate an SSH private/public key pair for your use, you can use the ssh-keygen command-line utility. You can run the ssh-keygen command from the command line to generate an SSH private/public key pair. If you are using Windows, by default you may not have access to the ssh-keygen command.

Anyone can encrypt a message by using your public key, but only you can read it. When you receive the message, you decrypt it by using your private key.
