AI summary
A method of cryptography is provided. The method can include executing portable binary instructions within a secure virtualized environment of a user agent, such as a web browser or another client application, to perform post-quantum custom encryption and/or decryption of a user request and/or a request response. The post-quantum custom encryption and/or decryption can comprise Quantum Secure Layer (QSL), Post-Quantum Transport Layer Security (PQTLS), Kyber, SABER, Enhanced McEliece, RLCE, or a National Institute of Standards and Technology (NIST) candidate post-quantum algorithm. The portable binary instructions may comprise a bytecode. The secure virtualized environment can comprise an independent context of execution within the user agent, with an independent memory space. For example, the independent context of execution may comprise a virtual machine (VM) and/or a portable binary or bytecode interpreter. The portable binary instructions may be encapsulated within a binary instruction module, which may be exchanged with another module.
