Difference between Encryption and Cryptography

Last Updated : 03 Sep, 2024

Encryption and Cryptography are the two terms that are generally used in Cyber Security. Encryption is the process in which the data should be securely locked which means only authorized users access the data while cryptography is the process of securing information or data by using cryptographic algorithms so that any hacker or unauthorized person does not steal your data. In this article, we will learn the differences between Encryption and Cryptography.

What is Encryption?

Encryption, as the name suggests, is generally a technique that is used to conceal messages using algorithms. It is the fundamental application of cryptography that encodes a message with an algorithm. It generally helps to protect private information, and sensitive data, and enhance the security of communication among client apps and servers. It is considered one of the most effective and popular data security techniques.

What is Cryptography ?

Cryptography, as name suggests, is generally study of methods like encryption. Its main objective is to provide methods simply to secure and protect information and communications using encryption and related techniques. It simply allows one to store sensitive information or transmit it across insecure networks so that it cannot be read or accessed by anyone except intended recipient. Its functions include authentication, nonrepudiation, confidentiality and integrity.

Difference Between Encryption and Cryptography

Encryption	Cryptography
It is a process of encoding message or information so that only authorized parties can have access to it.	It is study of techniques such as encryption for secure communication in presence of third parties.
It is considered as principal application of cryptography.	It is considered as art of creating codes using techniques of encryption and decryption.
It simply uses algorithm to encrypt data and secret key to decrypt it.	It simply provides methods of protecting data through encryption and its related processes.
It is all about mathematical and algorithmic in nature.	It is all about techniques and technologies in nature.
Its main purpose is confidentiality that means concealing content of message by translating it into code.	Its main purpose is to apply complex mathematics and logic to design strong encryption methods.
Types of encryption includes symmetric and asymmetric encryption.	Types of cryptography includes symmetric key cryptography and asymmetric key cryptography.
It provides security to data all times, maintains integrity, protects privacy, protects data across devices, etc.	In provides techniques like encryption techniques that can guard information and communication, cryptographic technique like MAC and digital signatures to protect information against spoofing and forgeries.
It follows same approach with some terms like ciphertext, plaintext, and cipher.	It has symmetric and asymmetric version with concept of shared and non-shared key.
It is useful to modern data security such as digital signatures and protect sensitive electronic data such as emails and passwords.	It is useful in electronic commerce, military communications, chip-based card payments, digital currencies, time stamping, etc.

Conclusion

In this article, we will cover the differences between Encryption and Cryptography. Both encryption and cryptography provide security that secures our data and information. But the difference is that encryption is securing the data by using encryption keys while in cryptography the data should be secure by applying privacy and other Confidential activities.
