Asymmetric algorithm of enciphering

The asymmetric algorithm of enciphering - the algorithm using two mathematically connected cryptographic a key (Key Pair). One key is called confidential (private Key) and is stored in the unavailable place. Other key is called open (public Key) and is freely provided to any potential users. Communication between open and confidential keys is so difficult that on condition of the sufficient length of keys it is impossible to calculate one key on the basis of another.

As a rule, the sender uses public key of the receiver for data encryption. Only the receiver has the connected secret key for interpretation of this message.

One of the most known algorithms - RSA. Sufficient key length for the majority of applications 1024 bits are considered today.
