SCP

SCP — Secure Copy Protocol. See official source.

Definition

SCP — Secure Copy Protocol, file-copy mechanism over SSH (RFC 4254). Considered legacy by the OpenSSH project, which recommends SFTP.

Origin

SCP derives from BSD rcp and was ported on top of SSH in the 1990s. Since OpenSSH 8.0 (April 2019), SCP is marked as legacy in favour of SFTP, but remains widespread in legacy EDI scripts.

Use

Legacy EDI pipelines still call scp in shell scripts to push files to a VAN; migration to SFTP/AS2 is part of common modernisation projects.
