An Applied Cryptography Developer designs, implements, and tests cryptographic algorithms and protocols to secure data and communications. They integrate these cryptographic systems into software applications, networks, and services to protect against unauthorized access or manipulation. Their work involves complex mathematics and programming, requiring a strong understanding of encryption techniques such as symmetric/asymmetric encryption, digital signatures, and hash functions. They also monitor for any potential security breaches or vulnerabilities and update cryptographic systems as needed. In addition, they must stay updated with the latest industry trends, threats, and compliance regulations. They often work closely with other cybersecurity and IT professionals.
