FormSeal — Supporting Tools
Small, purpose-built utilities for handling cryptographic material, keypairs, and encrypted payloads used by FormSeal.
Most tools run entirely locally in the browser. Some operations may require explicit backend authorization.
Available tools
Ciphertext blob decryptor
Lightweight interface for decrypting a single KV ciphertext payload using a provided X25519 keypair. Intended for testing malformed inputs, edge cases, and failure modes.
Open tool →KV exporter
Server-mediated utility for exporting multiple KV ciphertext
blobs into a .jsonl file. Export requests require
backend authorization via client-side Ed25519 signing.
KV-to-CSV converter
Local-only dashboard for decrypting KV exports (.jsonl) and converting them to CSV using X25519 private keys. Designed for processing submissions without server trust.
Open tool →Ed25519 keypair generator
Browser-based Ed25519 keypair generator for signatures and identity verification. Keys are generated locally and never persisted.
Open tool →X25519 keypair generator
Generate X25519 keypairs for public-key encryption using
libsodium sealed boxes (crypto_box_seal).
Only the public key is required for encryption; the
private key is needed solely for decryption.
Ed25519 keypair validator
Validate Ed25519 keypairs generated by any compliant tool. Base64url encoding only.
