cryptol
A domain-specific language for specifying, implementing, and verifying cryptographic algorithms with executable formal specifications.
What is cryptol?
Cryptol is a domain-specific language designed specifically for cryptography, originally created by Galois for the NSA Laboratory for Advanced Cybersecurity Research. It serves as a public standard for specifying cryptographic algorithms, providing executable formal specifications that can be used as documentation for cryptographic modules. Unlike traditional specification methods, Cryptol allows designers to test and verify their cryptographic designs incrementally as they evolve.
Cryptographers, cryptographic algorithm designers, educators, students, and developers working on cryptographic implementations who need precise, verifiable specifications. It's particularly valuable for those creating commercial or open-source cryptographic software that requires formal verification.
Cryptol offers a unique combination of executable specifications and formal verification capabilities, allowing cryptographic designs to be both tested and mathematically proven. Its integration with SMT solvers enables comprehensive verification that implementations meet their specifications, reducing errors in cryptographic software.
