A Trump administration executive order establishes binding deadlines for federal agencies and contractors to replace quantum-vulnerable cryptography: key establishment migration by December 31, 2030, and digital signature migration by December 31, 2031. The order targets the harvest-now, decrypt-later threat and mandates adoption of NIST FIPS 203 (ML-KEM), FIPS 204 (ML-DSA), and FIPS 205 (SLH-DSA). Any organization operating systems that process, store, or transmit federal data has contractual and regulatory obligations to begin cryptographic inventory and migration planning immediately.
