On October twenty-ninth, nineteen seventy-one, Daniel Julius Bernstein was born in East Patchogue, New York, USA. He is a mathematician, cryptographer, and programmer, and his academic field is cryptography, computer security, and algorithms.

Bernstein is one of the most influential modern contributors to practical cryptography and secure software. He is the creator of several fundamental and widely used protocols and algorithms, such as djbdns (a secure replacement for DNS servers), qmail (a secure mail server), and curve25519 (an advanced and very fast elliptic curve algorithm for encryption). Curve25519 is used today by billions of devices in protocols like Signal, WhatsApp, and SSH to secure their communication. Bernstein has also been a key figure in legal and political battles to ensure that cryptographic research and code are protected as speech under the U.S. Constitution. Through his technical work and his stance, he has set a new standard for openness, security, and reliability in software that the entire world depends on.
