OpenPGP (EDI)
On this page
OpenPGP for EDI payloads. See official source.
Definition
OpenPGP — RFC 4880 (November 2007), asymmetric encryption and signature format widely used to protect EDI files dropped on SFTP/FTPS.
Origin
Standardised by IETF from Pretty Good Privacy (Phil Zimmermann, 1991). RFC 4880 remains the widely implemented stable version, pending the successor (Crypto Refresh, RFC 9580).
Use
When a partner does not have AS2, the classic pattern is SFTP + OpenPGP: the sender signs and encrypts the EDI file with the recipient's public key, drops it, the recipient pulls and decrypts it.
