Encapsulate Your Data with FrodoKEM

Enter the recipient's FrodoKEM public key and your data below. Paste text (up to 1KB) or upload a file (up to 5MB). The tool automatically detects the FrodoKEM variant (640, 976, or 1344-AES) based on the public key for secure encapsulation.

Recipient's FrodoKEM Public Key (19232, 31312, or 43040 hex characters):

Or upload public key file (max 64KB):

Data to Encapsulate (max 1KB if pasted):

Or upload data file (max 5MB, any type - images, PDFs, etc.):

Beta Notice

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

How to Encapsulate Data with FrodoKEM

Bob wants to send quantum-safe encapsulated data to Alice. Alice generates her FrodoKEM keypair using our key generation tool and shares her public key. Bob uses this tool to encapsulate his data, which Alice can decapsulate with our decapsulation tool. For NIST-standardised encapsulation, try our ML-KEM encapsulation tool.
