Cryptography Encryption

Protecting data and information is very important in the digital era. Cryptography is a branch of science that focuses on techniques for protecting information and communications through the use of code so that only authorized parties can access and process the information. Cryptography ensures that data can only be read by authorized parties. Encryption techniques are used to convert data into a format that cannot be read by unauthorized parties. Cryptography helps ensure that data is not altered unlawfully during transmission. Techniques such as hashing are used to verify that data has not changed. Cryptography also provides a mechanism for verifying the identity of a user or system. This ensures that communication or data access is only carried out by authorized parties, as well as providing proof that an action or communication has been carried out. This prevents the party sending the message from denying that they sent the message. Digital signatures are one technique used for this purpose. Thus, cryptography plays an important role in ensuring that data remains secure, authentic, and cannot be accessed or changed by unauthorized parties.
