VerifiedSecurity Fundamentals

While working on Linux, a plain-text file (text.txt) must be transferred to another location. Which of the following methods can be used to verify data integrity and detect any change to that file?

Explanation

A SHA-256 checksum is a content-derived digest. Generating it for the source file and comparing it with the digest for the transferred copy detects any content change; matching digests indicate that the file contents are intact. GNU Coreutils documents that sha256sum computes SHA-2 checksums and can determine whether a file and checksum are consistent.
