How do I decrypt MD5?
MD5 is a hashing function. It is not encryption and there is no built-in mechanism to decrypt the information. You may use rainbow tables, if the string is not salted to attempt to get what the data could have been, except when two or more strings result in the same MD5 hash, so there is that too. 9.9K views.

Does MD5Sum output?
The md5sum command with the --status option does not produce any output but returns 0 if there are no changes and 1 if it detects changes. This argument is useful for scripting, where there is no need for standard output.
Is MD5sum safe?
Note: While md5sum is a reliable method for testing whether the file you received has been compromised, it is useful only if you know that the website you downloaded it from is secure.
