How to get the MD5 checksum for a file?
The HP-UX MD5 Secure Checksum A.01.01.02 bundle (bundle name MD5Checksum) provides a file integrity utility and API based on the standard Message Digest 5 (MD5) algorithm. The MD5Checksum bundle consists of the following two components that can be installed independently: – HP-UX MD5sum (md5sum checksum command)
What is the function of the md5sum command?
The md5sum command is based on the MD5 algorithm and generates 128-bit message digests. The md5sum command enables you to verify the integrity of files downloaded over a network connection. You can also use the md5sum command to compare files and verify the integrity of files.
Are there any other utilities like md5sum?
Three other utilities, sha1sum, sha256sum, and sha512sum, work the same way as md5sum. The md5sum command prints a 32-character (128-bit) checksum of the given file, using the MD5 algorithm. Following is the command syntax of this command-line tool:
When to use md5sum to warn of invalid hashes?
md5sum can let you know if you have invalid hashes when you compare files. To warn you if any hash values are incorrect, you can use the –warn option. For this last example, we will use sed to insert an extra character at the beginning of the third line. This will change the hash value in the file hashes, making it invalid.

How to compute the MD5 or SHA-1 cryptographic hash values?
You can use the File Checksum Integrity Verifier (FCIV) utility to compute the MD5 or SHA-1 cryptographic hash values of a file.
