yes , it can be done by editing its configuration. but experienced custom editing has to be done .. if not so the file or folder may be corrupted depending on its type.if u still want to know the process mail me ur request to " sureshmanickam2009@gmail.com ".
hash file organisation is containing the record of the file.
MD5 is a one-way hashing algorithm. If you take plain text and run it through the hashing algorithm, it produces a hash string such as the one in the question. If you take a file and compare it to the known hash that is supposed to have been produced from that file, you can tell if the file has been tampered with. If the hash of the file matches the hash you were provided that is supposed to have come from the file, then the file has not been altered - at least in theory. In reality, researchers have demonstrated that it is possible to create another file that will yield the same hash even though the files are different. With all that in mind, you should realize that you cannot go backwards from the hash to a unique initial text. There are literally an infinite number of files that can produce the same hash so you don't "decrypt" and MD5 hash.
Hashing a file is retrieving its unique hash. Any file is different and they all have other hashes. You can compare hashes with the fingerprint of a human. These hashes serve for many purposes.Virustotal.com for example, uses hashes to identify files which have already been scanned before. Many distributors of huge files (such as game clients or operating systems such as Ubuntu) often show the MD5 hash of the file. If you hash the file and get the same MD5 hash, the file has been downloaded entirely with no errors.You can hash a file using various applications. I use HashTab for that.
To verify that a file is not corrupted, you can check its checksum or hash value using algorithms like MD5, SHA-1, or SHA-256. First, compute the hash of the file and compare it to a known good value, which should be provided by the source of the file. If the computed hash matches the original hash, the file is likely intact; if not, the file may be corrupted. Additionally, you can attempt to open or run the file to see if it functions as expected, though this method is less definitive.
A hash cannot be "decrypted". It's a hash, meaning it's a validation of a file, to ensure the file's integrity. It's also constructed in a way, so it's virtually impossible to modify a file to match a specific hash value.
The same input will always produce the same hash. It is a one-way function, meaning it is difficult to reverse the process and obtain the original input from the hash. A small change in the input will produce a significantly different hash value.
The output from a hash function is referred to as the hash value, hash code, hash sum, checksum or just plain "hash" as in "the hash of the file is...". Generally a hash function is presumed to be secure or it wouldn't be used. If a hash is not secure it could be referred to as "worthless" or "false sense of security".
Lamport's hash implements a one-time password protecting against eavesdropping and password file theft.
File Hash
MD5 check sum is unique for a file content and is used to check the integrity of the file content. If file is to be transferred using network, recipient can calculate the MD5 hash and check it with the MD5 check sum of sender, if both are same, he can be sure of non-corruption of file in transit.
Publisher, path, and File hash Rules.
Hashing is an algorithm (hash function) to convert a string of characters into a fixed sized text using mathematical functions. The file to be hashed is known as “input” the algorithm used in known as ”hash function” and output is called “Hash Value”, some people call hash value as message digest. Hash value is the value that dictates what exactly in this file and always produces hexadecimal value. more on :networkingmania
