What is cryptography?

Cryptography is the practice and study of techniques used to secure communication and data from unauthorized access or alteration. It involves the use of mathematical algorithms to convert plain text into unintelligible ciphertext, which can only be understood by those who possess the appropriate key or password. Cryptography ensures the confidentiality, integrity, and authenticity of information by providing methods for encryption (converting plain text to ciphertext) and decryption (reverting ciphertext back to plain text). It plays a crucial role in areas such as online banking, secure communication, and data protection. With the rapid advancement of technology, cryptography continues to evolve to combat new threats and ensure the privacy and security of sensitive information in the digital age.
