What is Cryptography?
Cryptography is the science, as well as art which focuses on encryption of communication and information by using cipher codes. Its essential function is to provide data protection through encryption, which involves converting text into unreadable cipher text and so access by the wrong people can be prevented. Cryptographic techniques, by way of algorithms and keys, are used to encode and decode messages, being capable of discerning the original content only by authorized parties.
Cryptography Terminologies
- Plaintext: The medium, the non-encrypted source data, and the clear message.
- Ciphertext: The ciphertext is the form of incomprehensible plaintext. Only the encryption key can open the cipher and let the message be read.
- Encryption: The process of applying cryptographic algorithms and keys to convert the plaintext into ciphertext.
- Decryption: The process that is equivalent to encryption does decryption by way of converting ciphertext to plaintext with the aid of decryption keys.
Difference Between Cryptography and Cryptanalysis
Cryptography and Cryptanalysis overlap in the area of ensuring data protection. Cryptography sets up a secure communication and information protection process through the process of encryption, whereas cryptanalysis tests the strength of cryptographic algorithms and brings forward the vulnerabilities that the system might have.
In the realm of data security and information protection, two terms frequently surface cryptography and cryptanalysis, as two of its most critical components. Although these factors are designed to protect the same data confidentiality they have their attributes of encryption and decryption.
Such dissimilarity influences the manner of handling information protection and secure communication, so it is essential to keep that in mind. In the age of digital hacking sensitive information and cyber-attacks are facts, the knowledge of cryptography and cryptanalysis is essential. It is not just about applying security protocols, but it is also about regularly monitoring and improving safety features against continuously developing threats.
