How cryptography works?
1. Definition: Cryptography secures information by converting it into an unreadable form, accessible only to those with a special key. 2. Encryption : Plaintext data is transformed into ciphertext using an algorithm and a key, making the data unintelligible without the corresponding decryption key.Read more
1. Definition: Cryptography secures information by converting it into an unreadable form, accessible only to those with a special key.
2. Encryption : Plaintext data is transformed into ciphertext using an algorithm and a key, making the data unintelligible without the corresponding decryption key.
3. Transmission and Storage: The encrypted data can be safely transmitted or stored, as it remains unreadable to unauthorized parties.
4. Mathematical Principles: Modern cryptography relies on complex mathematical algorithms to ensure data security.
5. Symmetric Key Algorithms: These algorithms, such as AES, use the same key for both encryption and decryption.
6. Asymmetric Key Algorithms: These algorithms, such as RSA, use a pair of keys (public and private) for encryption and decryption.
7. Data Confidentiality: Cryptography ensures that sensitive information remains confidential and inaccessible to unauthorized users.
8. Data Integrity: It protects the data from being altered or tampered with.
9. Data Authenticity: Cryptography verifies the identity of the parties involved in communication, ensuring the data comes from a legitimate source.
10. Applications: Used in secure communication, data storage, online transactions, and many other digital security contexts.
