Cryptographic agilityGlossary · Cryptographic agility is the ability to swap algorithms and parameters without redesigning a system, a first-class requirement of the post-quantum era.
Cryptographic inventoryGlossary · Cryptographic inventory is the process of discovering and cataloging where cryptography is used in an organization, the first step of post-quantum migration.
Cryptographically relevant quantum computer (CRQC)Glossary · A cryptographically relevant quantum computer (CRQC) is a machine capable enough to break the public-key cryptography, such as RSA and ECC, in wide use today.
Harvest now, decrypt laterFoundations · Harvest now, decrypt later is an attack in which encrypted data is recorded today so it can be decrypted once quantum computers can break the encryption.
Is Bitcoin quantum safe?Blockchain · An evidence-based look at Bitcoin's quantum exposure: which coins have revealed public keys, how fast an attacker must be, and the proposed fixes.
Mosca's theoremGlossary · Mosca's theorem is an inequality that judges post-quantum migration urgency by comparing data secrecy time, migration time, and time to a quantum computer.
OpenSSL post-quantum supportMigration · OpenSSL added native ML-KEM, ML-DSA, and SLH-DSA support in version 3.5, an LTS release from April 2025 that also enabled hybrid post-quantum TLS key exchange.
Post-quantum blockchains (survey)Blockchain · A neutral survey of post-quantum signatures on blockchains, from QRL, Algorand, and BTX to Bitcoin and Ethereum research, with schemes and status compared.
Post-quantum cryptographyFoundations · Post-quantum cryptography is the field of cryptographic algorithms designed to resist attacks by both classical computers and future quantum computers.
Q-DayFoundations · Q-Day is the hypothetical future date when a cryptographically relevant quantum computer can break RSA and elliptic curve cryptography in practice.
