The «PIANO» cryptosystem provides protection safe PC communication, based on a principle asymmetric criptographic. In the “PIANO” cryptosystem, the length of a confidential session encryption key may be established by the user on a desirable degree of protection: 128, 256, 512, 1024 bits.
At an exchange, the document is encrypted by a confidential key (Diffie-Hellmans algorithm) and the digital signature (RSA algorithm) is added to it according to the chosen degree of protection.
