Encryption Exception Handbook for Trade Compliance Professionals

Developed by the SIA Encryption Exception Task Force, this handbook demystifies encryption export controls under the Export Administration Regulations (EAR §740.17). It traces the history of encryption from ancient ciphers to modern cryptography, clarifies distinctions between symmetric, asymmetric, and emerging quantum encryption, and provides step-by-step guidance on how to apply License Exception ENC for encryption commodities, software, and technology. The handbook includes key definitions, filing and reporting procedures (classification requests, semi-annual and self-classification reports), and practical examples to support accurate compliance practices for companies managing encrypted technologies worldwide.
