Tools for ISO 20022 and post-quantum migration.

Structured-address checker

Paste a pacs.008 or pain.001 party element and see whether its postal address meets the CBPR+ structured-address rules: structured, hybrid or unstructured, and why.

Rules: Town name and Country required, at most two address lines in hybrid form, no address held in free-text lines alone (the structured-address requirements). Swift planned to stop accepting unstructured addresses in November 2026 and delayed that release on 27 August 2026 (Bank of England).

ISO 20022 message identifier

Paste any ISO 20022 XML and get the message, version and business area from its namespaces.

PQC sizing calculator

Compare ML-KEM and ML-DSA key, ciphertext and signature sizes with RSA, ECDSA and X25519, and estimate the extra bytes per message and per day.

Sizes in bytes from NIST FIPS 203 (ML-KEM, Table 3) and FIPS 204 (ML-DSA, Table 2); RSA and ECDSA P-256 shown as raw public keys and signatures.
