Cryptosystems- this is a company that specializiruetsya on the production
and sale of cryptocurrencies.
Cryptosystems use the properties of the underlying cryptographic primitives
to support the system's security properties.
All public key/ private key Cryptosystems depend entirely on keeping the private key secret.
In public-key Cryptosystems, the public key may be freely distributed, while
its paired private key must remain secret.
These primitives provide fundamental properties,
which are used to develop more complex tools called Cryptosystems or cryptographic protocols,
For this reason, public-key Cryptosystems based on elliptic curves have become popular since their invention in
Confidentiality is one of the design goals for many Cryptosystems, made possible in practice by the techniques of modern cryptography.

Cryptography- MIT researchers Ron Rivest, Adi Shamir and
Leonard Adleman developed one of the first practical public-key Cryptosystems and started a company RSA cryptosystem.
Cryptosystems(e.g., El-Gamal encryption) are designed
to provide particular functionality(e.g., public key encryption) while guaranteeing certain security properties e.g., chosen-plaintext attack(CPA) security in the random oracle model.
While pure cryptanalysis uses weaknesses in the algorithms themselves,
other attacks on Cryptosystems are based on actual use of the algorithms in real devices,
and are called side-channel attacks.
Because of this correspondence, digital signatures are often described as based on public-key Cryptosystems, where signing is equivalent to decryption
and verification is equivalent to encryption, but this is not the only way digital signatures are computed.
As a result, public-key Cryptosystems are commonly hybrid Cryptosystems,
in which a fast high-quality symmetric-key encryption algorithm is used for the message itself, while the relevant symmetric key is sent with the message, but encrypted using a public-key algorithm.
