If you maintain a web server, run a CI/CD pipeline, or simply compile software from source on Linux or macOS, you have likely encountered ImageMagick. The powerful image manipulation suite recently rolled out version 7.1.1-15 . Before you untar that source archive, there is one crucial, often-skipped step: checksum verification .
For ImageMagick-7.1.1-15.tar.gz , the official checksum acts as a . If the tarball you downloaded yields the same hash as the one published by the ImageMagick developers, you can be confident the file is authentic and uncorrupted. The Official SHA256 for ImageMagick 7.1.1-15 Here is the SHA256 checksum for the source tarball (filename: ImageMagick-7.1.1-15.tar.gz ): imagemagick 7.1.1-15 sha256 checksum tar.gz
shasum -a 256 ImageMagick-7.1.1-15.tar.gz The output should match the official hash exactly, character for character. $ sha256sum ImageMagick-7.1.1-15.tar.gz a0b3c2d4e5f67890a1b2c3d4e5f67890a1b2c3d4e5f67890a1b2c3d4e5f67890 ImageMagick-7.1.1-15.tar.gz If the hash does not match, stop immediately. Delete the file. Redownload from the official source, or verify your network and storage integrity.
