The Types of Cryptographic Systems
Three types of cryptographic systems that are generally used are the following:
- Symmetric-key cryptography – Both the sender, as well as receiver, does share only one key. A sender utilizes this key for encrypting plaintext and sends the cipher text. And, the receiver does apply the same key for decrypting the message plus recover the simple text.
- Hash functions – In this algorithm, no key gets used. A definite length hash value gets computed according to the plain text which turns it difficult for the plain text contents to be recovered. The hash functions are used by operating systems for encrypting passwords.
- Public-key cryptography – It is a highly revolutionary concept and here, a couple of related keys, like private and public eye are used. Mostly, the public key is freely distributed whereas the private key continues to remain a secret. For encryption, the public key turns useful and for decryption, the private key gets used.

Features of Cryptography
Some remarkable features of cryptography have been mentioned below:
- Confidentiality – In cryptography, a person can access the information as it is intended for him and no other person other than him can have access to it.
- Non-repudiation – Both the creator and the sender of information will not be able to deny their intention for sending information at a later stage.
- Integrity – Information can’t be improved in transition or storage between the intended receiver and sender minus any inclusion to information that gets detected.
- Authentication – In cryptography, the identities of receiver and sender get confirmed besides the origin and destination of the information.
The Contribution of Cryptography for the Growth of Career
The notion of cryptography has risen in the previous 4-5 years and the significant companies, such as eBay, Uber, GEICO plus many more are hunting for professionals who have got expertise in this field. Beginning from developers, managers, and data scientists, everyone uses cryptography as this technology possesses a huge spectrum of employment opportunities for fresh and young professionals.
