How to calculate md5, sha1, sha256, sha512 checksum in Linux
Introduction
Checksums are used to verify the integrity of downloaded, transferred, or stored files. They ensure that the file has not been corrupted or tampered with in any way. Linux provides several tools to calculate the checksum values of files, including md5, sha1, sha256, and sha512. In this blog post, we will discuss how to calculate these checksum values in Linux.
md5
md5sum filename
sha
### sha1
shasum filename
### sha256
shasum -a 256 filename
### sha512
shasum -a 512 filename
Conclusion
Calculating checksum values of files is an important step in ensuring the integrity and security of data. In Linux, md5, sha1, sha256, and sha512 checksum values can be easily calculated using built-in tools like md5sum, sha1sum, sha256sum, and sha512sum. By verifying the checksum values of files, you can be sure that they have not been corrupted or tampered with.
