ASYMMETRICAL ENCRYPTION

ayshakhatunasha

Asymmetric encryption, or public-key cryptography, is a cryptographic system that uses public and private keys to encrypt and decrypt data. The public and private keys are very large numbers that are related to each other by a specific function, but in such a way that knowing one makes it extremely difficult to calculate the other.

The public key is transmitted via unprotected communication channels and is known to everyone. The public key is used to encrypt data and verify  the electronic signature of documents  (EDS).

A private key is used to decrypt the data, which is kept secret. Thus, the main advantage of asymmetric encryption over symmetric encryption is the ability of the parties to communicate and exchange data with each other without using secret communication channels.

The reliability of encryption (cryptographic strength) depends on the length of the key and increases exponentially as the key length doubles.

Asymmetric encryption is used in various protocols such as SSH, OpenPGP, S/MIME, and SSL/TLS, as well as in various systems that require establishing a secure connection over an unsecured network or verifying a digital signature.

The most common asymmetric encryption virtual phone number service algorithm is RSA, used in the SSL/TLS protocol and applied for both encryption and digital signature. The algorithm is based on the computational complexity of the problem of factoring large integers. The length of the RSA key is theoretically unlimited, but is usually between 1024 and 8192 bits.
