What is Cryptography?
Cryptography is the practice of securing information through mathematical techniques such as encryption, hashing, and digital signatures. It ensures that data remains confidential, integral, and authentic during storage and transmission.
Modern cryptography underpins many security technologies, including Transport Layer Security (TLS), Virtual Private Network (VPN), and Digital Certificates. It is a foundational component of Identity and Access Management (IAM) and secure communications.
What is Cryptography used for?
Cryptography is used to protect sensitive data from unauthorized access, ensuring confidentiality and integrity. It also supports authentication mechanisms and non-repudiation through digital signatures.
Organizations rely on cryptography to secure communications, protect Personally Identifiable Information (PII), and defend against attacks such as Packet Sniffing and Spoofing. It plays a critical role in Zero Trust architectures and modern security frameworks.
