#snsinstitutions #snsdesginthinkers #designthinking Cryptography is the science of securing information by transforming it into an unreadable format, ensuring that only authorized parties can access the original data. It involves techniques like encryption, which converts plaintext into ciphertext, and decryption, which reverses the process. Cryptography protects data confidentiality, integrity, and authenticity, making it a vital part of secure communication in digital systems. It is widely used in applications such as online banking, secure email, digital signatures, and VPNs to safeguard sensitive information from unauthorized access or tampering. There are two main types of cryptography: symmetric key cryptography, where the same key is used for both encryption and decryption, and asymmetric key cryptography, which uses a pair of public and private keys. Modern cryptographic algorithms, such as AES, RSA, and SHA, are designed to be highly secure against various attacks. By incorporating cryptography into systems and networks, organizations can protect data privacy, verify user identities, and maintain trust in electronic transactions.
