Cryptography is both the practice and study of the techniques used to communicate and/or store information or data privately and securely, without being intercepted by third parties. This can include processes such as encryption, hashing, and steganography. Cryptography is a broad field with applications in many critical areas of our lives.

Learn Cryptography is dedicated to helping people understand how and why the cryptographic systems they use everyday without realizing (such as banking transactions, website logins, etc) work to secure and protect their privacy.
