Decapsulate Your FrodoKEM Data

Enter your FrodoKEM private key and the encapsulated data below. Paste the encapsulated data (JSON format) or upload the file you received (up to 7MB). The tool automatically detects the FrodoKEM variant (640, 976, or 1344-AES) based on the private key for secure decapsulation.

Beta Notice

This tool is in beta while awaiting official NIST FIPS standardisation.

How to Decapsulate Data with FrodoKEM

Alice receives encapsulated data from Bob, created with our FrodoKEM encapsulation tool. She uses her private key, generated via our key generation tool, to decapsulate the data here (FrodoKEM decapsulation), recovering the original message. For NIST-standardised decapsulation, explore our ML-KEM decapsulation tool.

Why Use FrodoKEM for Quantum-Safe Decapsulation?

FrodoKEM leverages the Learning With Errors (LWE) problem to provide robust quantum-safe decapsulation. It supports variants 640, 976, and 1344-AES, offering flexibility for different security needs. We recommend FrodoKEM-976-AES for balanced performance and security (Level 3+). For additional protection, pair with a quantum-safe signature like ML-DSA using our signature tool.
