CIPHERPLUS is a Singapore deep-tech startup pioneering NIST-validated post-quantum cryptography.
We build trusted, future-proof tools that protect data throughout its lifecycle.
First in Singapore, First in ASEAN, 14th NIST CAVP in Asia
CIPHERPLUS is the first company in Singapore and ASEAN — and the 14th company in Asia — to obtain a U.S. National Institute of Standards and Technology CAVP certificate for its post-quantum cryptography algorithms, with full IP ownership.
Products
Shipping today. Built on our NIST-validated cryptographic library.
Quantum-safe file and folder encryption and decryption for Windows. Encrypt any document or folder for a specific recipient or group entirely offline using NIST FIPS 203 (ML-KEM) with FIPS 204 (ML-DSA) sender authentication. Recipients decrypt with one click — no shared secret, no password exchange.
Quantum-safe document signing and extraction for Windows. Sign contracts and legal documents entirely offline using NIST FIPS 204 (ML-DSA), then extract the original bytes back from any validated .proof file. Verification is free forever for every recipient.
Research Capabilities
