👉 A cryptographer is a person who specializes in cryptography and its applications. They are responsible for designing, implementing, and maintaining cryptographic systems that protect data and information from unauthorized access or manipulation by an attacker. Cryptographers often work with a variety of algorithms and techniques to create secure encryption schemes, such as public key cryptography, hash functions, and symmetric-key cryptography. They also play a critical role in the development of new technologies in the field of cryptography.
