MIRACL

MIRACL (formerly CertiVox) is a cryptography-focused authentication company headquartered in London, with roots in the open-source MIRACL cryptographic library originally developed in 1988 by Chief Cryptographer Dr. Michael Scott at Dublin City University. The library, which stands for Multiprecision Integer and Rational Arithmetic Cryptographic Library, is built on pairing-based and elliptic curve cryptography and is widely used by hardware manufacturers. The company's core product is a passwordless multi-factor authentication (MFA) solution based on the M-Pin Protocol — a zero-knowledge proof authentication protocol that eliminates password-based risk. This single-step passwordless MFA is designed to improve login success rates and reduce authentication friction for end users, with a particular focus on eCommerce platforms, iGaming operators, and online services where login abandonment and cart abandonment are measurable business problems. MIRACL targets organizations seeking to replace traditional password-based authentication with cryptographically strong alternatives that do not rely on Public Key Infrastructure (PKI). The company advocates for a distributed trust paradigm to replace monolithic certificate authorities, a vision partially realized through its involvement with the Apache Milagro open-source project. The company holds ISO 27001 accreditation and has partnerships with companies such as Playtech, Continent 8, and WA Technology. Historical customers have included the US Air Force, Intel, and Gemalto. MIRACL has received five rounds of investment funding from partners across North America, Asia, and Europe.
