Frequently Asked Questions

What is a Cryptographer?

A Cryptographer is a specialist who studies, designs and implements secure communication systems. They are responsible for developing encryption algorithms and creating secure protocols for protecting data.

What is the purpose of Cryptography?

The purpose of Cryptography is to protect data from unauthorized access by using mathematical algorithms to encrypt information. It is used to ensure the privacy and integrity of data being transmitted between two parties.

What are the two main types of Cryptography?

The two main types of Cryptography are Symmetric Key Cryptography and Asymmetric Key Cryptography. In Symmetric Key Cryptography, the same key is used to both encrypt and decrypt data. In Asymmetric Key Cryptography, two different keys are used to encrypt and decrypt data.

What is a hash algorithm?

A hash algorithm is a type of cryptographic algorithm that takes an input of any size and produces a fixed-length output. This output is known as a hash or message digest. The hash algorithm is used to verify the integrity of data by ensuring its accuracy and authenticity.

What is an elliptic curve cryptography?

Elliptic Curve Cryptography (ECC) is a type of public-key cryptography based on elliptic curves over finite fields. It is used for digital signatures, encryption and key exchange. ECC provides a higher level of security compared to other public-key cryptosystems due to its smaller key sizes and greater efficiency.
